Question

A gas is compressed by an isothermal process that decreases its volume by a factor of 2. In this process, the pressurea) does not changeb) increases by a factor of more than 2c) increases by a factor less than 2d) increases by a factor of 2

Answer 1

If the gas is an ideal gas, then the pressure will remain constant in an isothermal process. So the correct option is a.

In general, a gas is compressed by an isothermal process that decreases its volume by a factor of 2. In this process, the pressure will either remain constant (a) .

The behavior of the pressure in an isothermal process depends on the nature of the gas. If the gas is an ideal gas, then the pressure will remain constant since the temperature is constant and the ideal gas law states that pressure is proportional to the temperature. In this case, the answer would be (a).

Finally, if the gas is an ideal gas and the process is adiabatic, then the pressure will increase by a factor less than 2 (c). This is because adiabatic processes involve a decrease in temperature, leading to a decrease in pressure.
