When heat is absorbed by the ststem, the sign of the value of `q` is taken to be………….. .

A: Total enthalpy change of a multistep process is sum of Delta H_(1) + Delta H_(2) + Delta H_(3) + .... R: When heat is absorbed by the system, the sign of q is taken to be negative.

When no heat is absorbed by the system them from the surroundings, but work (w) is done on the system, the change in internal energy of the system is given as

Express the change in internal energy of a system when (i) No heat is absorbed by the system from the surroundings, but work (w) is done on the system. What type of wall does the system have ? ii) No work is done on the system, but q amount of heat is taken out from the system and given to the surroundings. What type of wall does the system have? (iii) w amount of work is done by the system and q amount of heat is supplied to the system. What type of system would it be?

If q is the amount of heat absorbed by the system and W the amount of work done on the system (+ve) , the change in the energy of the system is given by:

If a gas is taken A to C through B then heat absorbed by the gas is 8 J. Heat absorbed by the gas in taking it from A to C directly is -

A thermodynamics system is taken through the cyclic process abca as shown in the figure. If the heat absorbed by the gas during the cycle is 5x joule then find the value of x.

Suppose 300J of work done on a system and 70cal . Of heat heat is extracted from the system. What are the values of dW , dQ and dU with proper signs?

If a gas is taken from A to C through B then heat absorbed by the gas 8 J . Heat absorbed by the gas in taking it from A to C directly is

One mole of ideal monoatomic gas is taken round the cyclic process as shown in figure. The heat rejected by the gas in the path is ………...and the heat absorbed by the gas in the path AB is ………...........
