Thermodynamics

Question 1

The graphical representation of the change in state of a gas by thermodynamic process is called

Answer 1

Indicator diagram

Question 2

Enthalpy is

Answer 2

Measure of total heat content of the system

Question 3

Entropy is

Answer 3

Measure of disorderness in the system.

Question 4

The parameters which determines the state or condition of a system are called

Answer 4

Thermodynamic state variable or thermodynamic coordinates

Question 5

Isotherm

Answer 5

The pressure volume curve for a fixed temperature

Question 6

The state of thermodynamics system is characterised by its

Answer 6

Internal energy

Question 7

Internal energy can change through two modes

Answer 7

Work and heat

Question 8

First law of thermodynamics

Answer 8

dQ= dU+dW

Question 9

Molar specific heat capacity of the substance

Answer 9

C = S/n = dQ/ndT
C depends on the nature of the substance, its temperature and the conditions under which heat is supplied

Question 10

For a mole of solid the total energy is

Answer 10

U = 3kbT x na
=3RT

Question 11

kbT X na

Answer 11

R

Question 12

Which does not agree with predicted values 3R

Answer 12

Carbon

Question 13

Thermodynamics is a

Answer 13

Macroscopic science

Question 14

Internal energy equals to

Answer 14

The algebraic sum of kinetic and potential energy

Question 15

Zeroth law of thermodynamics

Answer 15

Two systems in thermal equilibrium with a third system separately are in thermal equilibrium with each other
