When people run quickly, they can sweat profusely. Their muscles undergo movement, and the loss of energy takes place. Based on this description, in which two ways is energy conserved when people run?
Heat energy is released from the body to the surroundings.
Heat energy is taken from the surroundings to the body.
Chemical energy is converted to mechanical energy that’s used for muscle movements.
Radiant energy is converted to mechanical energy that’s used for muscle movements.
Heat energy is converted to mechanical energy that’s used for muscle movements.

Answer: Chemical energy is converted to mechanical energy that’s used for muscle movements.

Heat energy is converted to mechanical energy that’s used for muscle movements.

Step-by-step explanation:

According to the I law of thermodynamics, energy can neither be created cannot be destroyed but it can only change its form. In the given situation, the energy can only be conserved when it is not lost to the environment. The chemical energy is produced in the body in the form of ATP which is converted into mechanical energy to allow the movement of the muscles during running. So, chemical energy is converted into mechanical energy by this way. The heat energy when directly converted into mechanical energy to induce the movement of muscles the energy will remain conserved and will not lost to the environment.
