The increase of pressure on a gas decrease of its volume.    This also increases its temperature. In naturally temperature or heat is nothing or nor less than speed of molecular motion. The object or substance is hot when the molecules   move   fast. The object is cold when molecules move slowly. In a piece of ice molecules are motion slowly they all more or less hang together. When the ice remains is solid. If the ice is heated it melts. Then molecules begin to move faster and they can no longer hang together to from a solid. And the ice convert to water. When the water is heated its boiled   and create vapor where all molecules move so faster and jump clear to liquid. When a cubic volume pressure increase that’s time heat increase. It has been seen that gaseous molecules are move so fast than other molecules.
