it is converted into other forms of energy....
It is given off as heat.
The energy not used to make ATP molecules generates heat.
You then have a source of heat that can be used to warm a room or make coffee.
When a heat source loses energy, the energy is transferred to the surroundings in the form of heat.
Yes. This happens, for example, when steam is used to raise something like a balloon.
what happened to the energy that is not stored in your body
Energy that cannot be used to do work is typically converted into heat. This is known as waste energy. In most systems, waste energy is dissipated into the environment, contributing to increasing overall entropy.
Basically the same that happens to heat energy left anywhere else. It can stay warm for a while, but eventually, the heat will dissipate.
It may - this usually happens when you burn it.
The 62 percent of the total energy of glucose that is not used to make ATP is released as heat during cellular respiration. This excess energy is a byproduct of the energy conversion processes that occur in the cell.
When you burn oil to heat your house, the potential energy stored in the oil is converted into heat energy. This heat energy is then used to warm up the air inside your house, providing you with a source of warmth.
Chemical energy can be "used" (ie changed from one form to another) through a chemical reaction. Energy may be released in many forms, including heat.
