An ideal gas goes from the state i to the state f as shown in the figure. The work done by the gas during the process. An ideal gas goes from the state i to the state f as shown in the figure. The work done by the gas during the process. September 8, 2021 [...]

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 The work done in the process [...]

A system is given 300 calories of heat and it does 600 joules of work. How much does the internal energy of the system change in this process (J=4.18 “joules”/cal) A system is given 300 calories of heat and it does 600 joules of work. How much does the internal energy of the system change [...]

In a thermodynamics process pressure of a fixed mass of a gas is changed in such a manner that the gas molecule give out 20 joule of heat and 10 joule of work is done on the gas. If the initial internal energy of the gas was 40 joule, then the final internal energy will [...]
