Our body contains ______________ potential energy from food we have eaten.
Alisiya [41]

Answer: Our body contains chemical potential energy from food we have eaten.

This chemical potential energy is transformed into the kinetic energy of our hands and arms as we rub our hands together.

As our hands move past each other and rub against each other, friction allows the kinetic energy to be transformed into thermal energy on the surface of our hands.

Explanation:

It is true that our food contains chemical bonds and these bonds have potential energy stored. So, when we eat food then our body acquires chemical potential energy.

When we rub our hands and arms then they form kinetic energy as atoms present within the skin of our hands come into motion. This rubbing of hands leads to the formation of heat which means thermal energy is being generated.

Thus, we can conclude that our body contains chemical potential energy from food we have eaten.

This chemical potential energy is transformed into the kinetic energy of our hands and arms as we rub our hands together.

As our hands move past each other and rub against each other, friction allows the kinetic energy to be transformed into thermal energy on the surface of our hands.

Which would you expect to freeze faster pure water or salt solution why?
krek1111 [17]
Pure water.

A salt solution contains impurities whereas pure water will not contain any impurities.

Impurities increase the boiling point (freezing point) of a substance.

Thus, I would expect the pure water solution to freeze faster than the salt solution.
