We understand 'temperature' as a measure of the 'hotness' or 'coldness' of a body. Which of these properties do you think explicitly depend on the temperature?

The correct options are
A Density of a liquid
B Length of a metal rod
C Pressure exerted by a gas inside a closed chamber
Let us look at some real-life examples.
(1)The density of water is seen to be 1 kg/m3 only at 40C. At 800C, it is seen to get reduced to 0.971 kg/m3.
(2)A plastic bottle half-filled with water often shrinks when kept inside the refrigerator.
(3)If you keep heating a car tyre, which is made of a certain sturdy rubber, it will explode at some point.
Although it is unscientific to make general statements based on singular observations, we are inclined, at this point, to make the following guesses -
(1) The density of water decreases with increasing temperature
(2) Decreasing temperature shrinks a plastic bottle
(3) Since we can assume the tyre is sturdy and will not leak easily, an explosion will only be due to an increase in the pressure of air inside.
Thus, all the properties listed from (a) to (c) seem to explicitly depend on temperature. Mass does not change with a change in temperature.
