As the temperature of a gas is increased,
is a reversible physical change that occurs when a substance changes from one state of matter to another
all particles of matter are in constant motion
zero (flat)
Because freezing is an exothermic reaction, the water gives off heat to its surroundings, thereby warming up the oranges.
the kinetic energy of its particles increases.
is the energy an object has due to its motion
occurs when a substance absorbs energy during a phase change
frost on a windshield is an example of this phase change
Phase change
is a reversible physical change that occurs when a substance changes from one state of matter to another
all particles of matter are in constant motion
zero (flat)

When the cold threatens the oranges in Florida, growers spray the oranges with water so the water freezes. How does this save the oranges?
