A fixed quantity of a gas undergoes a change in temperature from 100 K to 200 K and a change in pressure from 2 atm to 1 atm. After theses changes, the volume of the gas is
Explanation
Answer: Four times the original volume
The pressure, temperature, and volume of a gas are related by the ideal gas law, PV=nRT. Solving for volume gives the equation V=(nRT/P). The molar quantity of gas (n) is constant, so the equation reduces to V=T/P. In the context of the question, temperature is doubled while pressure is halved, resulting in a four-fold increase in volume.
