Question

question 12 of 25
you have two pieces of metal. metal a has a higher temperature than metal b. what does this tell you about them?
a. the molecules in metal a are vibrating faster.
b. metal b has more heat energy.
c. metal a has more gravitational potential energy.
d. there is more light energy in metal b.

Explanation:

Temperature is related to the average kinetic energy of molecules. Higher - temperature substances have faster - vibrating molecules. Heat energy depends on mass and specific heat capacity in addition to temperature. Gravitational potential energy depends on height and mass, not temperature. Light energy is not related to the temperature of the metals in this context.

Answer:

A. The molecules in metal A are vibrating faster.
