A system is changed from state `A` to state `B` by one path and from `B` to `A` by another path. If `DeltaE_(1)` and `DeltaE_(2)` are the corresponding changes in internal energy, then

A

`U_1 +U_2 =+ ve `

B

`U_1+U_2 =- ve `

C

`U_2 -U_1 =0`

D

`U_2 +U_1 = 0`

Text Solution

Verified by Experts

The correct Answer is:

In a change from state A to state B

Let Delta U_(1) and Delta U_(2) be the changes in internal energy of an ideal gas in the processes A and B then

If a system undergoes an adiabatic change from state 1 to state 2, the work done by the gas is:

An ideal gas is taken from state 1 to state 2 through optional path A, B, C and D as shown in the PV diagram. Let Q, W and U represent the heat supplied, work done and change in internal energy of the gas respectively. Then,

If DeltaH is the change in enthalpy and DeltaE the change in internal energy for a gaseous reaction then

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.

When a system goes from state A to state B, it is supplied with 400 J of heat and it does 100 J of work. (a) For this transition, what is the system's change in internal energy? (b) If the system moves from B to A, what is the change in internal energy? (c) If in moving from A to B along a different path in which W_(AB)^'=400J of work is done on the system, how much heat does it absorb?
