The mass and diameter of a planet are twice those of earth. The period of oscillation of pendulum on this planet will be (if it is a second’s pendulum on earth)

An asteroid of mass m is approaching earth, initially at a distance of 10 Re with speed vi It hits the earth with a speed vf (Re and Me are radius and mass of earth), then

Kepler’s second law regarding constancy of aerial velocity of a planet is a consequence of the law of conservation of

5.6 litre of helium gas at STP is adiabatically compressed to 0.7 litre. Taking the initial temperature to be T₁, the work done in the process is

In a given process for an ideal gas, dW = 0 and dQ<0 Then for the gas

A perfect gas goes from state A to another state B by absorbing 8×10^5 J of heat and doing 6.5×10^5 J of external work. It is now transferred between the same two states in another process in which it absorbs 10^5 J of heat. Then in the second process

A gas is enclosed in a cylinder with a movable frictionless piston. Its initial thermodynamic state at pressure Pi = 10^5 Pa and volume Vi = 10^-3 m3 changes to a final state at Pf = (1/32) × 10^5 Pa and Vf = 8 × 10^-3 m3 in an adiabatic quasi-static process, such that P3 V5 = constant. Consider another thermodynamic process that brings the system from the same initial state to the same final state in two steps: an isobaric expansion at Pi followed by an isochoric (isovolumetric) process at volume Vf. The amount of heat supplied to the system in the two-step process is approximately

One mole of diatomic ideal gas undergoes a cyclic process ABC as shown in figure. The process BC is adiabatic. The temperatures at A, B and C are 400 K, 800 K and 600 K respectively. Choose the correct statement

An ideal gas is taken through the cycle A→B→ C → A, as shown in the figure. If the net heat supplied to the gas in the cycle is 5 J, the work done by the gas in the process C → A is

Which of the following graphs correctly represents the variation of β= -(dV/dP)/V with P for an ideal gas at constant temperature
