Question

Which of the following will cause an increase in gas pressure in a closed container? A. Lowering the temperature B. Reducing the volume C. Adding more gas D. both B. and C

Answer 1

D. both B and C will cause gas pressure to decrease because adding more gas is like adding more energy and reducing the space (volume) the atoms will move more quickly but won't have space, therefore pressure will increase.

Answer 2

Answer:

D. both B. and C

Explanation:

From the ideal gas law we have

$pV=nRT\\\Rightarrow p=\frac{nRT}{V}$

Where,

p = Pressure

V = Volume

R = Gas constant

T = Temperature

n = Number of moles

Here, it can be seen that if the volume of the container decreases then the pressure will increase.

If the volume of the gas increases without changing the dimensions of the container then the pressure will increase. More amount of gas in the same volume will increase pressure.
