Heating and Cooling Curve

• A change of state can be brought about by putting heat into a system or removing it from the system.
• The temperature of a system will not change if the substance is undergoing a change from solid to liquid to gas, as well as the reverse.
• Freezing is the opposite of melting.
• Evaporation occurs when a liquid turns to a gas.
• Condensation is the opposite of vaporization.
• Deposition is the opposite of sublimation
• Freezing. Opposite of melting, and both represent the equilibrium between the solid and liquid states.
• Evaporation. Occurs when a liquid turns to a gas.
• Condensation. Opposite of vaporization, and both represent the equilibrium between the liquid and gas states.
• Deposition. Opposite of sublimation, and both represent the equilibrium between the solid and gas states.
