Something about volume, temperature and pressure?

Question

The volume of a fixed mass of gas is affected by temperature and pressure.Which one of the following statements show the correct relationship among volume, temperature and pressure.

Change in volume Change in pressure Change in temperature

a)Decrease increase Increase

b)increase decrease Same

c)Same increase Decrease

d)Decrease same Increase

Answer 1

B.

As you increase the volume, the presure decreases with no change to the temperature.

Answer 3

PV/T = constant; P=pressure, V=volume, T=temperature

the answer is A

T is directly proportional to PV

V is directly proportional to T/P

P is directly proportional to T/V

as the V increase, the P will decrease and the T will decrease

or instead.
