The absolute temperature of a sample of monatomic ideal gas is doubled at constant volume. What effect, if any, does this have on the pressure and density of the sample of gas? Pressure Density

1. Remains the same Doubles

2. Doubles Multiplied by 4

3. Doubles Remains the same

4. Remains the same Remains the same

5. Multiplied by 4 Doubles

option (3)

Explanation:

According to the ideal gas equation

PV = nRT

where, P is pressure, V is volume, R is gas constant and T be the absolute temperature.

At constant volume,

P ∝ T

If the temperature is doubled, the pressure also doubled.

As volume is constant, so the density is also constant.

So, the pressure is doubled and the density remain constant.
