Thermal expansion
________: the property of many materials to increase in volume when heated and contract when cooled.
Convection
________: movement of thermal energy as fluids move.
Calorimeter
________: a device that enables scientists to measure the thermal energy transferred in reactions and between systems.
Radiation
movement o energy in the form of electromagnetic waves.
Temperature
the measure of the hotness or coldness of a substance; proportional to the average kinetic energy of the particles within the substance.
Caloric theory
________: the now- obsolete theory that stated that heat was an invisible self- repelling fluid.
Thermodynamics
________: the study of thermal energy and heat and how they relate to work and other forms of energy.
Specific heat
________: the energy required to raise the temperature of 1 g of a substance 1 degree Celsius.

first law of thermodynamics
the law that states that energy cannot be created or destroyed but only transferred between objects or transformed; also known as law of conservation of energy
second law of thermodynamics
the law that states that energy can flow from a colder object to a warmer object only if something does work
third law of thermodynamics
the law that states that entropy would be at its minimum value at absolute zero

second law of thermodynamics
the law that states that energy can flow from a colder object to a warmer object only if something does work
third law of thermodynamics
the law that states that entropy would be at its minimum value at absolute zero. Therefore, absolute zero can never be achieved
