If `DeltaU` and `Delta W` represent the increase in internal energy and work done by the system resectively in a thermodynamical process, which of the following is true?

A

`DeltaU=-DeltaW`, in a adiabatic process

B

`DeltaU=DeltaW`, in a isothermal process

C

`DeltaU=DeltaW,` in a adiabatic process

D

We consider a thermodynamic system. If DeltaU represents the increase in its internal energy and W the work done by the system, which of the following statements is true?

What will happen to internal energy if work is done by the system?

If DeltaQ and represent the heat supplied to the system and the work done on the system respectively, then the first law of thermodynamics can be written as

The first law thermodynamics was gives as q=Delta U+(-w) , where q is heat given to a system and Delta U represent increase in internal energy and -w is work done by the system. Various process such as isothermal, adiabatic, cyclic, isobaric and isochoric process in terms to first law of thermodynamics leads for important results. The molar heat capacity for 1 mole of monoatomic gas is 3/2R at constant volume and 5/2R at constant pressure. Which of the following statements are correct:

The molar heat capacity for 1 mole of monoatomic gas is 3/2R at constant volume and 5/2R at constant pressure. A system is allowed to move from state A to B following path ACB by absorbing 80 J of heat energy. The work done by the system is 30 J. The work done by the system in reaching state B from A is 10 J through path ADB which statements are correct : 1. Increase in internal energy from state A to state B is 50 J. 2. If path ADB is followed to reach state B. Delta U = 50J 3. If work done by the system in path AB is 20 J, the heat absorbed during path AB = 70 J. 4. The value U_(C)-U_(A) is equal to U_(D)-U_(B) . 5. Heat absorbed by the system to reach B from A through path ADB is 60 J.

State true or false, internal energy of a gaseous system depends upon thermodynamic process.

The first law of thermodynamics was given as q=DeltaU+(-w) , where q is heat given to a system and DeltaU represents increase in internal energy and -w is work done by the system. Various processes such as isothermal, adiabatic, cyclic, isobaric and isochoric process in terms of I law of thermodynamics leads for important results. The molar heat capacity for 1 mole of monoatomic gas is 3/2 R at constant volume and 5/2 R at constant pressure. Which of the following statements are correct? (1) Both work and heat appears at the boundaries of system. (2) Heat given to a system is given +ve sign. (3) Heat given to a system is equal to increase in internal energy under isothermal conditions (4) Heat given to a system is used to increase internal energy under isochoric conditions (5) Both work and heat are not state functions but their sum (q+w) is state function.
