If the amount of heat given to a system be 35 joules and the amount of work done on the system be 15 joules , then the change in the internal energy of the system is

If amount of heat supplied is Q ,work done is W and change in internal energy is nC_(V)dT then relation among them is. (C_(V)) = gram specific heat

If the amount of heat given to a system is 3 5 J and the amount of work done on the system is 15 J, then the change in internal energy of the system is

In the figure an ideal gas changes is state from state A to state C by two paths ABC and AC. (a) Find the path along which the work done is least. (b) The internal energy of the gas at A is 10 J and the amount of heat supplied to change its state to C through the path AC is 200 J. Calculate the internal energy at C. (c) The internal energy of the gas at state B is 20 J. Fid the amount of the heat supplied to gas to go from A to B.

First law of thermodynamics is the general law of conservation of energy as applied to heat energy. According to this law, whenever heat is added to a system, it transforms to an equal amount of some other forms of energy. If dQ= a small amount of heat supplied to the system, dW= small amount of work done by the system and dU= small change in internal energy of the system, then dQ=dU+dW . Read the above passage and answer the following questions: (i) The amount of heat obsorbed by a gas is 10 cals and work done on the gas in 58J . Calculate increase in internal energy of the gas. (ii) What values of life do you learn fron this law?
