To determine what will happen to the pressure in your tires if the temperature drops 40 degrees over the night, you need to understand the relationship between temperature and pressure in a closed system.
According to Charles's Law, the volume of a gas is directly proportional to its temperature (assuming constant pressure), while according to Boyle's Law, the pressure of a gas is inversely proportional to its volume (assuming constant temperature).
In this case, since the tires are a closed system, the volume remains constant. However, due to the decrease in temperature, according to Charles's Law, the pressure will also decrease.
Therefore, the answer is b) Pressure will decrease.
