The absolute temperature of a gas is increased four times while maintaining a constant volume. what happens
pressure of the gas?
it decreases by a factor of four.
it increases by a factor of four.
it decreases by a factor of eight.
o tincreases by a factor of eight.

It increases by a factor of four

Explanation:

Boyle's Law : At constant temperature , the volume of fixed mass of a gas is inversely proportional to its pressure.

pV = K.......(1)

pV = constant

Charles law : The volume of the gas is directly proportional to temperature at constant pressure.

V = KT

or V/T = K = constant ....(2)

Applying equation (1) and (2)

According to question ,

T2 = 4 (T1)

V2 = V1

Put the value of T2 and V2 , The P2 can be calculated,

V1 and V1 cancel each other

T1 and T1 cancel each other

We get,

or

P2 = 4 P1

So pressure increased by the factor of four

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
