Thermal Energy and heat Flashcards
What is conduction?
Conduction is when thermal energy is transferred from one object to another through direct contact.
What is convection?
Convection is the transfer of thermal energy by the movement of liquid or gas.
What is radiation?
Radiation is the transfer of thermal energy by electromagnetic waves.
What is heat?
Heat is the energy that is transferred between objects at different temperatures.
What is thermal energy?
Thermal Energy is the total kinetic energy of all the particles that make up a substance.
What is temperature?
Temperature is the average kinetic energy of the particles in an object.
What is a insulator?
Insulators are poor conductors of heat.
What is a conductor?
Conductors are materials that transfer heat well.
What is thermal equilibrium?
Thermal equilibrium is when two objects that are connected and have different temperatures , eventually they will end up at the same temperature.
What is expansion?
Expansion is an increase in the volume of a substance while its mass remains the same.
What is contraction?
Contraction is the decrease in size of an object thats cooling.
