While researching scuba diving, pablo reads how hot a tank should get while being filled with air. which law  best  explains why the scuba tank would heat up?

gay-lussac’s law, because as the pressure decreases, the temperature increases

gay-lussac’s law, because as the pressure increases, the temperature increases

boyle’s law, because as the volume decreases, the temperature increases

boyle’s law, because as the pressure increases, the temperature increases

Gay-Lussac’s law, because as the pressure increases, the temperature increases

Explanation:

First of all, we can notice that the volume of the tank is fixed: this means that the volume of the air inside is also fixed.

This means that in this situation we can apply Gay-Lussac's law, which states that:

"for a gas kept at constant volume, the pressure of the gas is proportional to the absolute temperature of the gas".

Mathematically:

where p is the pressure in Pascal and T is the temperature in Kelvin.

In this case, the tank is filled with air: this means that the pressure of the gas inside the tank increases. And therefore, according to Gay-Lussac's law, the temperature will increase proportionally, and this explains why the tank gets hot.
