Question

Explain the energy transformations that make this possible. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. Our body contains (a) potential energy from food. We have (b) 1 of 5. This (c) potential energy is transformed into the (d) kinetic energy of our hands and arms as we rub our hands (e) 2 of 5. As our hands move past each other and rub against each other, friction allows the (f) kinetic energy to be transformed into (g) thermal energy on the surface of our hands. (h) 3 of 5.

Answer 1

(a) Potential energy from food

(b) Chemical energy

(c) Chemical energy

(d) Mechanical energy

(e) Through the process of rubbing

(f) Mechanical energy

(g) Thermal energy

(h) 4 of 5.

Step-by-step explanation:

1. Potential Energy from Food (a): The energy transformations begin with the potential energy stored in the food we consume. This potential energy is primarily in the form of chemical energy.

2. Chemical Energy (b): The chemical energy from our food is a type of potential energy that can be released during metabolic processes. This energy is the source of power for various physiological functions.

3. Transformation to Mechanical Energy (c, d, e): When we rub our hands together (e), the potential energy stored in our muscles is converted into kinetic energy, specifically mechanical energy. This energy allows the movement of our hands and arms, transforming the stored potential energy into the kinetic energy of motion.

4. Friction and Thermal Energy (f, g): As our hands move past each other, friction comes into play. Friction transforms the mechanical energy into thermal energy (heat) on the surface of our hands. This transformation is a result of the resistance encountered during rubbing.

5. 4 of 5 (h): The phrase "4 of 5" suggests that this step is one of the five recognized forms of energy transformations. In this context, it refers to the transformation of mechanical energy into thermal energy through the process of friction.
