Can someone asnwer these 3 questions for me?

Question

First Question: If pressure goes up, volume goes _________ while temperature is being held constant.

Second Question: If volume goes up while holding temperature constant, what happens to the pressure?

Third Question: If pressure goes up while volume is being held constant, what happens to the temperature?


I cant figure it out & I looked it but can someone please help me?

Answer 1

this can help too:
PxV=nxRxT
if P goes up with V constant, T goes up
if V goes up with P const, T goes up
if P goes up and V goes down, T is const.

Answer 2

These are all applications of gas laws. See your chem book for a discussion of gas laws.
First question, as pressure increases, volume decreases if temperature is constant . (Boyle's law)
Second question: As volume increase, pressure must decrease if temperature is constant. (Boyle's law)
Third question: As pressure increases, temperature increases if volume is constant. (Gay-Lassac law)

HOPE THIS HELPS ;>)
