When touching objects have the same temperature, or when the molecules are moving at the same rate - Thermal equilibrium, The transfer of thermal energy between two regions that are different temperatures - Heat, Heat flows from _____ to _____ - Hot to cold, What are two factors that affect the rate of heat - Temperature and material, The total kinetic energy and potential energy in a system - Thermal energy, What units is thermal energy measured in - Joules, The measurement of kinetic energy in a particle, how fast the particles are moving - Temperature, What are three scales used to measure temperature - Celsius, Kelvin, Fahrenheit, This needs less energy to raise temperature - Low heat capacity, This needs more energy to raise temperature - High heat capacity, The transfer of heat by light waves - Radiation, The transfer of heat by direct contact - Conduction, The transfer of heat by circulation of matter due to density - Convection, Where thermal energy spreads fast - Conductor, This slows down the transfer of thermal energy - Insulator, In every energy transformation, some energy is always released as _____ energy - Ke, What are four factors that affect thermal energy - Temperature, state of matter, Mass, material, What formula do we use to calculate thermal energy - Q = MC deltaT, What does each letter represent in the formula Q = MC deltaT - Q=thermal energy released, m = mass, c = heat of water (1), deltaT = change in temperature (the difference),
