There's actually a question to it too

8

anonymous · Answer

wat is the question?

anonymous · Answer

A 20 liter sample of gas is kept under a constant pressure of 100 kPa. The temp is lowered from 360 K to 90 K. What is the new volume

anonymous · Answer

should've been the main question!

anonymous · Answer

Ha so would it still be 8 cubic liters?

anonymous · Answer

@agent0smith

agent0smith · Answer

Use gas laws, V1/T1 = V2/T2

anonymous · Answer

guide me through? not sure where to palce the numbers.

anonymous · Answer

this is the math part of physics where I'm bad again. :P Proves my calc too

anonymous · Answer

wait let me try

anonymous · Answer

100/20 = 360/90
5/4 = 1.25
is that it?

agent0smith · Answer

idk, i'll check in a sec, just plug the numbers in where they belong. Initial and finals

anonymous · Answer

still can't get it. wha do you think?

agent0smith · Answer

Identify what all the variables are. What is T1, V1 etc

anonymous · Answer

V1 = 100 Kpa
t1= 360k
t2 = 90k

anonymous · Answer

I don't think i'm right. ha physics.

agent0smith · Answer

KPa is a unit of pressure.

anonymous · Answer

V1 = 360k
v2 = 90k
t1 = 100 kpa?

anonymous · Answer

Is that right?

agent0smith · Answer

KPa is a unit of pressure.

agent0smith · Answer

uh wow you're all over the place :P

V1 = 360k
v2 = 90k

V1 and V2 are volumes, not temperatures.

agent0smith · Answer

A 20 liter sample of gas is kept under a constant pressure of 100 kPa. The temp is lowered from 360 K to 90 K. What is the new volume

read carefully and identify each quantity that you'll need in V1/T1 = V2/T2

anonymous · Answer

so 100 kpa is the t1?

agent0smith · Answer

Again....
KPa is a unit of ***pressure***.

T1 is initial temperature and T2 is final temperature

V1 is initial volume and V2 is final volume

anonymous · Answer

I'm confused man

agent0smith · Answer

er by what...?

anonymous · Answer

i don't know what to plug into what.

agent0smith · Answer

Don't plug ANYTHING in until you know what's what.

A 20 liter sample of gas is kept under a constant pressure of 100 kPa. The temp is lowered from 360 K to 90 K. What is the new volume

read carefully and identify each quantity that you'll need in V1/T1 = V2/T2

T1 is initial temperature and T2 is final temperature

V1 is initial volume and V2 is final volume

Identify what each one is.

anonymous · Answer

360 K v1
90k v2
100 kpa t1

agent0smith · Answer

None of those are correct.

anonymous · Answer

PLease help me now my brain is turning into liquid

agent0smith · Answer

You don't seem to know what any of these things are... you need to read your notes or book or something.

V1 or V2 is volume. Measured in litres often.
T1 or T2 is temperature. Measured in degrees Kelvin often.



And again, kPa is a unit of PRESSURE. NOT a measure of temperature or volume.

anonymous · Answer

t1 90k
t2 360k
v1 = 100 L

agent0smith · Answer

Good. Now V2 is your unknown. But make sure you study your notes/book, you can not expect to answer these questions if you have no idea what temperature/volume/pressure are.

anonymous · Answer

wait my algebra's rusty too. sorry bro im a muscles and no brain/.

anonymous · Answer

324 cubic liters?

agent0smith · Answer

$$\Large \frac{ V_1 }{ T_1 } = \frac{ V_2 }{ T2 }$$

anonymous · Answer

100/30=v2/360

anonymous · Answer

so...

anonymous · Answer

100
____  =  v2
              /360
30

anonymous · Answer

36000/30=1200!!!!!!!!!!!!!!!!!!!!!!!!!!!!

agent0smith · Answer

t1 90k
t2 360k
v1 = 100 L

Take a look at these, then your equation. I don't see a 90 in yours.

anonymous · Answer

36000/90=400!

agent0smith · Answer

wait your numbers were wrong. 

A 20 liter *********V1****** sample of gas is kept under a constant pressure of 100 kPa. The temp is lowered from 360 K *******T1******* to 90 K ********T2******. What is the new volume V2

agent0smith · Answer

lol btw when i google your profile pic (which obv isn't you haha), google says this about the pic:

"Best guess for this image: really gay" hahaha

anonymous · Answer

oh that cross the line mister!
20    v2
-       -
360   90
1800/360 = 5 cubic liters?

agent0smith · Answer

lol right click your profile pic, then click search google for this image, see for yourself! it's hilarious, the results

5 looks right

agent0smith · Answer

liters aren't cubic, though. Liters are liters.

anonymous · Answer

the shooter? what the? lololololololol

agent0smith · Answer

lol idk this is what google gives me:

Best guess for this image: really gay

Search Results
Who's Really Gay? - YouTube
