Question

The temperature of a certain mass of gas in a rigid container is doubled. If initial pressure of gas is 1atm. Find the percentage increasing in the pressure (assume that volume is constant).​

Answer 1

Answer:

The percentage change in the pressure of a given mass of a gas filled in a container at constant temperature=100%

Find the percentage change in its volume=?

According to Charles and Boyle's law

PV=constant

If pressure increases, the volume decreases

Answer 2

Answer:

100percent

Explanation:

if the volume is constant,

P is proportional to {P=pressure,t=temperature}

if the temperature is doubled,

then, the the pressure will be doubled

then the pressure will increase 100 percent
