Question

The pressure of a gas at 10 degrees Celsius is greater than the pressure of the gas at 30 degrees Celsius. (Points : 2)
       True 
       False

aaronq · Answer

use this formula  $\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}$

aaronq · Answer

remember to use the absolute temperature scale

anonymous · Answer

but i don't know the pressure for both temperatures

aaronq · Answer

you could plug any arbitrarily for the first and see what you get for the second.

you should know from kinetic theory (of gases) that higher temperatures yield higher average kinetic energies of particles which exert a higher pressure on the container that they're in.

anonymous · Answer

I figured out the answer is false

anonymous · Answer

and I'm pretty sure it's because pressure rises as temperature rises

aaronq · Answer

yeah, that's exactly it. if you look at PV=nRT, you can see that P and T are directly proportional.
