Question

heating and cooling curves
heating curves
a heating curve shows how the
(y - axis) changes as a substance is heated up at a
constant rate over (x - axis)
point a - substance exists at a
state. as time passes, is added
to the substance. this causes the molecules of the
substance to more rapidly which
we detect by an increase in in the
substance.

Explanation:

A heating curve is a graphical representation. The y - axis represents temperature as it is the property that changes when a substance is heated. The x - axis represents time as heating is done at a constant rate over time. At point A, the substance is in a solid state. Heat is added over time. When heat is added, the molecules of the substance vibrate (for solids) or move more rapidly (in general). An increase in the kinetic energy of the molecules (which is related to molecular motion) is detected as an increase in temperature.

Answer:

Temperature; Time; solid; heat; move (or vibrate); temperature
