Robert leaves a chocolate bar in his car while attending school all day. When he goes to his car in the afternoon, the bar has changed into a gooey liquid. Which statement BEST explains what happened to Robert's chocolate bar?

• The energy from the sun caused the chocolate to melt.

• The chocolate in the bar spread out due to entropy loss.

• The energy holding the solid bar together was lost over time and it became liquid.

• The liquid was the original state of the chocolate and over time it returned to this state.

Whenever there is a change of state, such as a solid to liquid or liquid to gas, heat energy can be added without a temperature change because

• the added energy is not needed.

• the energy is lost to the system.

• the change of state requires energy.

• the energy is lost to the atmosphere.
