If a gas is heated up, its particles move around more quickly. They hit the walls of their container harder and more often. This increases the pressure. Sometimes the pressure gets so great that the container bursts.

 Heat is caused by a Mechanical energy is produced as a heat  whenever you bounce a ball. Each time the ball hits the ground, some of the energy of the ball's motion is converted into heating up the ball. That's why it slows down at each bounce.

Thermal energy can be produced to other objects causing them to heat up.Just like when u heat up a pot of water.The heat from the stove causes the molecules in the pan to vibrate faster making  the pot to heat up quicker.
