Question 1.
Fill in the blanks and rewrite the sentence.
a. The amount of water vapor in air is determined in terms of its …………
b. If objects of equal masses are given equal heat, their final temperature will be different. This is due to difference in their ……………...
c. During transformation of liquid phase to solid phase, the latent heat is ………….
Answer:
(a) The amount of water vapor in air is determined in terms of its temperature.
Explanation:
The amount of vapor needed to saturate the air depends on temperature of the air.
⇒ If the temperature is low, less vapor is needed to saturate the air.
⇒ If the temperature is high, additional vapor will condense.
(b) If objects of equal masses are given equal heat, their final temperature will be different. This is due to difference in their specific heat capacity.
Explanation:
The amount of heat energy required to raise the temperature of a unit mass of an object by 1°C is called the specific heat capacity of that object.
(c) During transformation of liquid phase to solid phase, the latent heat is absorbed.
Explanation:
During transition of solid phase to liquid phase, the objects absorbs heat energy. This heat energy is used for breaking the bonds between the atoms or molecules in the solid and transform it into solid phase.
