Which of the following parameters does not characterize the thermodynamic state of matter?
1 Temperature
2 Pressure
3 Work
4 Volume
Explanation:
C Those physical quantities whose value depend only upon the state of the system and does not depend upon the path by which this state has been attained are said to be state function. Here, work is depending upon the path of the system. Thus, work is not a thermodynamic state of function.

Liquid is filled in a flask upto a certain point. When, the flask is heated, the level of the liquid
1 immediately starts increasing
2 initially falls and then rises
3 rises abruptly
4 falls abruptly
Explanation:
B The liquid and the flask undergoes volume expansion and the flask expands first therefore the level of the liquid initially falls and then rises.

A cycle tyre bursts suddenly. What is the type of this process?
1 Isothermal
2 Adiabatic
3 Isochoric
4 Isobaric
Explanation:
B When a tyre bursts suddenly energy is not immediately transferred between the system and the surrounding. So, the process is adiabatic. There sudden expansion of its air into the atmosphere is adiabatic and the tyre is cooled. In adiabatic process, heat neither enters the system nor leaves the system.

When the temperature of a gas is increased
1 its molecular kinetic energy increases
2 molecular potential energy decreases and molecular kinetic energy also decreases; total energy remaining constant
3 molecular potential energy increases and molecular kinetic energy decreases; total energy remaining constant
4 its molecular potential energy increases
Explanation:
A When the temperature of gas increased its molecular kinetic energy increases. Because a gas molecules are in a state of constant random motion. They posses kinetic energy. When a gas is heated, the average kinetic energy per molecule of the gas increases. As a result, its temperature rises. The average kinetic energy per molecule is proportional to the absolute temperature of the gas.
