Question

Meredith takes a glass of water outside on a hot summer day and leaves it there for several hours. When she returns, part of the water has evaporated and there is less water in the glass. What kind of state change did some of the water go through to make it disappear?
A. It changed from a solid to a gas.
B. It changed from a gas to a liquid.
C. It changed from a liquid to a solid.
D. It changed from a liquid to a gas.

Answer 1

d. it changed from a liquid to a gas.

Answer 2

Answer:

D. It changed from a liquid to a gas.

Explanation:

The water in the glass experiences a phenomenon called Evaporation, resulting from the heat of the atmosphere (as it is a hot summer day). The surface layer of the water in the glass will experience a change in state from liquid to gas and the layer beneath it will follow until a noticeable decrease in the water height in glass is present. This state change makes some of the water 'disappear'
