Thermal Energy

QuestionAnswer
Thermal energy The total kinetic and potential energy of all the particles in an object.
The amount of thermal energy depends on the.... Amount of substance. (the more substance the more thermal energy)
Thermal equilibrium The transfer of energy from high to low until they reach the same point.
Heat Energy transferred between 2 objects. (joules)
Temperature The average amount of kinetic energy in the particles of an object.
The more kinetic energy... The higher the temperature.
The less kinetic energy... The lower the temperature.
Temperature is not determined by the... Amount of substance.
Thermometer Measures temp.
Heat transfer Transfer of energy between objects that are different temperatures.
Conduction Transfer of energy from one substance to another. (through direct contact)
Conduction can... occur within a substance.
Convection Transfer of thermal energy by the movement of a liquid or gas.
Convection current Circular movement or liquids or gasses.
Radiation Transfer of energy through matter or space as electromagnetic waves.
All objects... Radiate electromagnetic waves.
Conductors Materials that conduct heat well. (ex. metals)
Insulators Materials that don't conduct heat well. (ex. air wool)
Thermal expansion is another word for... Contraction.
During thermal expansion, The substances volume increases due to the increase in temperature.
Expansion joints Parts of bridges or roads that allow the road to expand due to temperature increase.
During actual change of state, Temperature doesn't increase of decrease. (looks flat on a graph)
