The process of a gas turning into a liquid by giving out heat energy ………..

Statements given below are incorrect. Write the correct statements: The process by which a gas change to a liquid state at some fixed temperature, with the absorption of heat energy is called vaporisation.

Heat is tranmitted in liquids by the process of :

The process due to which a solid changes into liquid state at some fixed temperature by absorption of heat energy is known as

In a given process work done on a gas is 40 J and increase in its internal energy is 10J. Find heat given or taken to/from the gas in this process.

During a process ideal gas expands to compress the spring such that 10kJ energy is stored in the spring and 2kJ heat is released from gas to surrounding find the change in internal energy of gas

The process of boiling needs an external source of heat energy.

On heating the liquid, do the particles gain or lose energy.

An ideal gas is taken round a cyclic thermodynamic process ABCA as shown if Fig. If the internal energy of the gas at point A is assumed zero while at B it is 50 J. The heat absorbed by the gas in the process BC is 90 J. (a) What is the internal energy og the gas at point C ? (b) How much heat energy is absorbed by the gas in the process AB? (c ) Find the heat energy rejected or absorbed by the gas in the process CA. (d) What is the net work done by the gas in the complete cycle ABCA ?

Assetion : The temperature of a gas does not change when it undergoes on adiabatic process Reason: During adiabatic process , heat energy is exchanged between a system and surroundings.

p-V diagram of an ideal gas for a process ABC is as shown in the figure. (a) Find total heat absorbed or released by the gas during the process ABC. (b) Change in internal energy of the gas during the process ABC. (c) Plot pressure versus density graph of the gas for the process ABC.
