12th-cet

For adiabatic expansion of a perfect monoatomic gas when volume increases by 24%, what is the percentage decrease in pressure?

12th-cet

Which of the following p-V diagrams best represents an isothermal process?

12th-cet

1 mm³ of gas is compressed at 1 atm pressure and temperature 27°C to 627°C What is the pressure under adiabatic condition?

12th-cet

In the following figure, four curves A, B, C and D are shown. The curves are

12th-cet

In an adiabatic change, the pressure and temperature of monoatomic gas are related with relation p∝T^C, where C is equal to

12th-cet

A gas is suddenly expanded such that its final volume becomes 3 times its initial volume. If the specific heat at constant volume of the gas is 2R, then the ratio of initial to final pressure is nearly equal to

12th-cet

Which property of the system does not change in an adiabatic process?

12th-cet

During an adiabatic process, the cube of the pressure is found to be inversely proportional to the fourth power of the volume. Then the ratio of specific heats is

12th-cet
