Question

Match each energy transformation scenario with the correct description of energy change at the molecular or atomic level: Melting ice
Burning methane Exciting neon atoms Compressing a spring
(2 points)
Burning methane
Compressing a spring
Exciting neon atoms
Melting ice
:: Potential energy of molecules increases as their relative positions change from solid to liquid.
:: Elastic potential energy is stored due to the change in the relative positions of the spring's parts.
:: Chemical energy stored in bonds is converted into thermal and light energy.
:: Electrons absorb electrical energy and move to higher energy levels.

Answer 1

Melting ice -> Potential energy of molecules increases as their relative positions change from solid to liquid.

Burning methane -> Chemical energy stored in bonds is converted into thermal and light energy.

Exciting neon atoms -> Electrons absorb electrical energy and move to higher energy levels.

Compressing a spring -> Elastic potential energy is stored due to the change in the relative positions of the spring's parts.
