MAHARASHTRA BOARD CHEMISTRY CHAP 10 CLASS 11 STATE OF MATTER GAS LAW STOICHIOMETRY solution

A. A balloon is inflated with helium gas at room temperature of 25°C and at I bar pressure when its initial volume is 2.27L and allowed to rise in air. As it rises in the air external pressure decreases and the volume of the gas increases till finally it bursts when external pressure is 0.3bar. What is the limit at which volume of the balloon can stay inflated ? (Ans:7.567L)

j Calculate the pressure in atm of 1.0 mole of helium in a 2.0 dm' container at 20.0°C. (Ans:12.02 atm)

k Calculate the volume of I mole of a gas at exactly 20 °C at a pressure of 101.35 kPo. (Ans: 24.055 dm')

best lyrics

Late at night, in summer heat

Expensive car, empty street

There's a wire in my jacket for this is my trade

It only takes a moment, don't be afraid

I can hotwire an ignition like some kind of star

Just a poor boy in a rich man's car

So I whisper to the engine and flick on the lights

And we drive into the night

Oh, the smell of the leather always excites my imagination

And I picture myself in this different situations

I'm a company director, two kids and a wife

I get the feelin' that there's more to this one's life

There's some kind of complication, t he tells her he's alone

Spends the night with his lover, there's a trace of her cologne

And the words of his mistress, as she whispers them so near

Start ringin' in my ear

Please, take me dancin' tonight

I've been all on my own

You promised one day we could

It's what you said on the phone

I'm just a prisoner of love

Always hid from the light

Take me dancin'

Please, take me dancin' tonight

I imagine his wife, she don't look nothing like a fool

She picks the kids up from some private school

She remembers what he told her, he was late and worked alone

But there's more than a suspicion in this lingering cologne

And the kid's just won't be quiet and she runs a traffic light

And she drives into the night

Please, take me dancin' tonight

I've been all on my own

You promised one day we could

It's what you said on the phone

I'm just a prisoner of love

Always hid from the light

Take me dancin'

Please, take me dancin' tonight

So here I am

In a stolen car at a traffic light

They go from red to green

So I just drive into the night (drive her)

Stolen Car (Take Me Dancing)

Song by Sting

---------------------

Mitchell’s poetic ode to an inescapable love, one she knows could be wrong for her, but is now in her soul, has become one of her most enduring classics. It has never gone out of style in pop culture, having appeared in films like Practical Magic and been recorded by Prince, Tori Amos, k.d. lang, Diana Krall and more. in the 1971 review of Mitchell’s Blue, where the song first appeared, Rolling Stone wrote, “She has given us some of the most beautiful moments in recent popular music.”

Just before our love got lost you said

"I am as constant as a northern star"

And I said, "Constantly in the darkness

Where's that at?

If you want me I'll be in the bar"

[Verse 2]

On the back of a cartoon coaster

In the blue TV screen light

I drew a map of Canada

Oh, Canada

With your face sketched on it twice

Oh, you are in my blood like holy wine

You taste so bitter and so sweet

Oh, I could drink a case of you, darling

And I would still be on my feet

Oh, I would still be on my feet

[Verse 3]

Oh, I am a lonely painter

I live in a box of paints

I'm frightened by the devil

And I'm drawn to those ones that ain't afraid

[Verse 4]

I remember that time you told me, you said

"Love is touching souls"

Surely you touched mine

'Cause part of you pours out of me

In these lines from time to time

[Chorus]

Oh, you are in my blood like holy wine

You taste so bitter and so sweet

Oh, I could drink a case of you, darling

Still I'd be on my feet

I would still be on my feet

Lyrics

On a dark desert highwayCool wind in my hairWarm smell of colitasRising up through the airUp ahead in the distanceI saw a shimmering lightMy head grew heavy and my sight grew dimI had to stop for the night

There she stood in the doorwayI heard the mission bellAnd I was thinking to myself"This could be Heaven or this could be Hell"Then she lit up a candleAnd she showed me the wayThere were voices down the corridorI thought I heard them say

Welcome to the Hotel CaliforniaSuch a lovely place (such a lovely place)Such a lovely facePlenty of room at the Hotel CaliforniaAny time of year (any time of year)You can find it here

Her mind is Tiffany-twistedShe got the Mercedes BenzShe got a lot of pretty, pretty boysThat she calls friendsHow they dance in the courtyardSweet summer sweatSome dance to rememberSome dance to forget

So I called up the Captain"Please bring me my wine"He said, 'We haven't had that spirit hereSince 1969"And still those voices are calling from far awayWake you up in the middle of the nightJust to hear them say

Welcome to the Hotel CaliforniaSuch a lovely place (such a lovely place)Such a lovely faceThey livin' it up at the Hotel CaliforniaWhat a nice surprise (what a nice surprise)Bring your alibis

Mirrors on the ceilingThe pink champagne on iceAnd she said, 'We are all just prisoners hereOf our own device"And in the master's chambersThey gathered for the feastThey stab it with their steely knivesBut they just can't kill the beast

Last thing I remember, I wasRunning for the doorI had to find the passage backTo the place I was before"Relax, " said the night man"We are programmed to receiveYou can check out any time you likeBut you can never leave"

Winter

Song by Tori Amos

Snow can wait, I forgot my mittens

Wipe my nose, get my new boots on

I get a little warm in my heart when I think of winter

I put my hand in my father's glove

I run off where the drifts get deeper

Sleeping Beauty trips me with a frown

I hear a voice, "You must learn to stand up

For yourself 'cause I can't always be around"

He says, when you gonna make up your mind?

When you gonna love you as much as I do?

When you gonna make up your mind?

'Cause things are gonna change so fast

All the white horses are still in bed

I tell you that I'll always want you near

You say that things change, my dear

Boys get discovered as winter melts

Flowers competing for the sun

Years go by and I'm here still waiting

Withering where some snowman was

Mirror, mirror, where's the crystal palace?

But I only can see myself

Skating around the truth who I am

But I know, Dad, the ice is getting thin

When you gonna make up your mind?

When you gonna love you as much as I do?

When you gonna make up your mind?

'Cause things are gonna change so fast

All the white horses are still in bed

I tell you that I'll always want you near

You say that things change, my dear

Hair is grey and the fires are burning

So many dreams on the shelf

You say I wanted you to be proud

I always wanted that myself

When you gonna make up your mind?

When you gonna love you as much as I do?

When you gonna make up your mind?

'Cause things are gonna change so fast

All the white horses have gone ahead

I tell you that I'll always want you near

You say that things change, my dear

Never change

All the white horses aah-aah

Mmm-mmm

On a Bus to St. Cloud

Song by Trisha Yearwood

On a bus to St. Cloud, Minnesota

I thought I saw you there

With the snow falling down

Around like a silent prayer.

And once on a street in New York City

With the jazz and the sin in the air

And once on a cold LA freeway

Going nowhere.

And it's strange but it's true

I was sure it was you

Just a face in the crowd

On a bus to St. Cloud.

In a church in downtown New Orleans

I got down on my knees and prayed

And I wept in the arms of Jesus

For the choice you made.

We were just gettin' to the good part

Just gettin' past the mystery

Oh, and it's just like you

It's just like you to disagree.

And it's strange but it's true

You just slipped out of view

Like a face in the crowd

On a bus to St. Cloud.

And you chase me like a shadow

And you haunt me like a ghost

And I hate you some and I love you some

But I miss you most.

--- Instrumental ---

On a bus to St. Cloud, Minnesota

I thought I saw you there

With the snow falling down

Around like a silent prayer...
