melting wax\n evaporating gasoline\n freezing water\n these changes are all examples of\n a nuclear changes.\n b physical changes.\n c chemical changes.\n d energy consumption.

Answer

Brief Explanations:

Melting wax, evaporating gasoline, and freezing water are changes in state (solid - liquid - gas) without altering the chemical composition of the substances. Physical changes involve changes in physical properties like state, shape, or size, but not in chemical identity. Nuclear changes involve changes in the nucleus of an atom, chemical changes result in new substances being formed, and energy consumption is a more general concept not specific to these types of state - change processes.

Answer:

B. physical changes
