A gas sample is held at constant temperature. What happens to the pressure of the sample if the volume is doubled and the number of molecules is doubled?
A: The pressure decreases to 25% of its initial value.
B: The pressure quadruples.
C: The pressure is unchanged.
D: The pressure doubles.

Answer 1

pV=mRT/M; p=mRT/MV;p=Nrt/v

Of molecules increased by 2 times, and also increased by a factor of 2

p in direct ratio n

p inversely V

p-Do not change

Answer C
