a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object
an instrument that measures and indicates temperature
the temperature at which molecular energy is at a minimum
the energy transferred between objects that are at different temperatures
Thermometer
the temperature at which molecular energy is at a minimum
an instrument that measures and indicates temperature
a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object

Absolute Zero
the height at which molecular energy is at a minimum
the rate at which molecular energy is at a max
the temperature at which molecular energy is at a minimum
the temperature at which molecular energy is at a max
Heat
the energy that is transferred as electromagnetic waves, such as visible light and infrared waves
the movement of matter due to differences in density that are caused by temperature variations
the transfer of energy as heat through a material
the energy transferred between objects that are at different temperatures
Thermal conduction
the transfer of energy as heat through a material
a machine that transforms heat into mechanical energy, or work
the energy transferred between objects that are at different temperatures
Heat transfer always occurs from the object to the object.
