Water can exist in three states: solid Ice, liquid water, and
gaseous water vapor. It takes a
certain amount of heat before
water can change state. Use the
following information to sketch the
graph of the function representing
the temperature of water as a
function of the amount of total
heat added in Joules (1). Explain
why this situation involves
piecewise function.
