What involves extensive in depth studies of an individual?

b) Pressure and internal energy increases.

Explanation: According to the temperature and pressure law, also known as Gay-Lussac's Law, pressure and temperature are directly proportional, which means that when temperature increases so does pressure and vice-versa, so, since temperature increased, pressure will also increase.

Internal Energy (Thermal Energy) is the total amount of energy associated with the motion of the atoms or molecules in the system. Temperature and Internal Energy are also directly proportional, because, as temperature increases, the movement of the particles increases and so do its internal energy. So, as temperature rises internal energy also rises.

For this bottle, as temperature rises, both pressure and internal energy also rises, so the right alternative is "Pressure and internal energy increases."
