Astudent rapidly rubs the palms of both hands

together, after eating lunch. which sequence

correctly describes the energy transformations that

occur?

a. chemical mechanical heat

b. mechanical heat chemical

c. heat mechanical chemical

d. mechanical nuclear heat

Option a

Explanation:

The action of the rapid rubbing of the hands are a result of chemical reaction and responses that takes place inside our body.

When we rub our hands together, that shows the mechanical motion of the body or we can say that while rubbing hands chemical energy gets converted to mechanical energy (here, Kinetic energy).

While rubbing, due to friction, heat is produced and hence we can say that this mechanical energy has transformed to heat energy.

Thus the conversion here is from chemical to mechanical to heat energy.

answer would be d.) i hope this
