Assertion : Internal energy change in the heat evolved or absorbed at constant pressure.
Reason : Internal energy is state function.

Assertion :- Change in internal energy is zero for all gases at constant temperature. Reason :- Internal energy is function of temperature only.

Assertion (A): Internal energy change in a cyclic process is zero. Reason (R ) : Internal energy is a state funciton.

Internal Energy As A State Function And Heat

Assertion :- Internal energy of a real gas may change during expansion at const. temperature. Reason :- Internal energy of a real gas ia function of T & P .

Assertion : The internal energy of an isothermal process does not change. Reason : The internal energy of a system depends only on pressure of the system.

There is no change in internal energy for an ideal gas at constant temperature. Internal energy of an ideal gas is a function of temperature only.

When gas is given heat DeltaQ , a part of heat energy is utilized into work done W by gas and the remaining part is utilized to change in internal energy. An ideal diatomic gas is heated at constant pressure, the ratio of the internal energy change to heat energy supplied, is

Which of the following statement is correct? (A) only internal energy is a state function but not work (B) only work is a state function but not internal energy (C) Both internal energy and work are state functions (D) Neither internal energy nor work is state function

Assertion : Internal energy is an extensive property. Reason : Internal energy depends upon the amount of the system.
