3. The combustion of a fuel is generally favored because of the large increase in entropy due to
A. the formation of a smaller amount of product molecules.
B. the formation of a larger number of product molecules.
C. the distillution of the products in the air.
D. the exothermic reaction.

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
