Which of the following illustrates a phase change? a. gasoline evaporating into the air b. a helium balloon rising into the sky c. air leaking from a tire d. plasma erupting from the sun

A. Gasoline evaporating into the air

Explanation:

The matter can exists in any of the three forms that are solid, liquid and gas. Phase change may occur in different forms such as solid, liquid and gas. The gasoline is a volatile liquid which when exposed to the air can change it's phase from liquid to vapors on evaporation.
