Exothermic change
all particles of matter are in constant motion
Because freezing is an exothermic reaction, the water gives off heat to its surroundings, thereby warming up the oranges.
occurs when a substance releases energy to its surroundings during a phase change
is a reversible physical change that occurs when a substance changes from one state of matter to another
the kinetic energy of its particles increases.
is the energy an object has due to its motion
he freezing point of nitrogen is lower than the freezing point of carbon dioxide.
frost on a windshield is an example of this phase change
