Heat And Thermodynamics Mock Tests

An ideal gas undergoes an isothermal expansion at temperature T. Which of the following is true?

An ideal gas undergoes an isothermal process from an initial state to a final state. The work done by the gas is 200 J. The change in internal energy of the gas is:

In an isothermal expansion, a gas does 200 J of work on its surroundings. The heat absorbed by the gas is:

The first law of thermodynamics is a statement of conservation of:

The Stefan-Boltzmann law states that the total energy radiated per second per unit area of a black body is proportional to:

An ideal gas undergoes an adiabatic compression such that its volume becomes half of the initial volume. If gamma = 1.4, the ratio of final pressure to initial pressure is:

The process of conduction of heat takes place in:

An adiabatic process is one in which:
