Case Study 2: States of matter viz: solid, liquid, and gas are functions of temperature and heat content. During the change of state of a substance, the exchange of heat takes place between the substance and its surrounding. In this process temperature of the substance remains constant. At a certain temperature known as the melting point. Both the solid and liquid states of the substance coexist in thermal equilibrium. Similarly, at boiling point both the liquid and vapor states of the substance co-exist in the thermal equilibrium. There are certain substances which on heating directly pass from solid to vapor state without passing through the liquid state. This is a sublimation process in which the solid changes to the vapor state of the substance. The process of change of state depends on pressure and temperature.
The states of matter, such as solid, liquid, and gas, are dependent on what factors?
a) Density and Mass
b) Temperature and Heat Content
c) Volume and Weight
d) Pressure and Density
Answer: b) Temperature and Heat Content
What happens to the temperature of a substance during its state change?
a) It increases continuously
b) It decreases continuously
c) It fluctuates randomly
d) It remains constant
Answer: d) It remains constant
At the melting point, which states of a substance coexist in thermal equilibrium?
a) Solid and Liquid
b) Liquid and Gas
c) Solid and Gas
d) All states
Answer: a) Solid and Liquid
At the boiling point, which states of a substance coexist in thermal equilibrium?
a) Solid and Liquid
b) Liquid and Gas
c) Solid and Gas

Answer: b) Liquid and Gas
What is the process called when a substance changes directly from a solid to a gas without passing through the liquid state?
a) Condensation
b) Evaporation
c) Sublimation
d) Vaporization
Answer: c) Sublimation
What factors does the process of change of state depend upon?
a) Density and volume
b) Pressure and temperature
c) Mass and weight
