How is the air pressure of a tire on a cold day different from the air

pressure of the same tire on a hot day? (Assume that the volume of air
is the same and that there are no leaks in the tire.)

Answer:

The air pressure on a hot day is higher than on a cold day

Step-by-step explanation:

In tire having constant volume, the air pressure on hot day is greater compared to that on a cold day.

From the combined gas law, at constant volume, it can be deduced that the pressure of a given mass of gas varies directly with the absolute temperature.

Mathematically;


(P_(1) )/(T_(1) ) =
(P_(2) )/(T_(2) )

So, it can be inferred that the higher the temperature of the tire, the more the pressure on the air inside and vice versa.
