Thermal Energy Heat

Thermal Energy

Thermal Energy The total energy of all the particles in an object Depends on…… temperature of the object # of particles in the object the arrangement of the particles in the object

Temperature Measure of average kinetic energy of the particles F- boiling = 212 - freezing = 32 C- boiling = 100 -freezing = 0 Kelvin- boiling = 373 - freezing = 273 Absolute zero = -273 Celsius

Heat The transfer of thermal energy is heat. Moves from a warmer object to a cooler object Specific Heat – the amount of energy required to raise the temperature of 1 kilogram of a material by 1 Kelvin. (in Joules)

Heat always flows from warmer to cooler objects. Cup gets cooler while hand gets warmer Heat The flow of thermal energy from one object to another. Heat always flows from warmer to cooler objects. Ice gets warmer while hand gets cooler

Specific Heat Materials with high Specific Heat can absorb a great deal of energy without a great change in temperature. Ex: Water requires 4,180 joules to raise the temperature 1 degree Kelvin.

Land heats up and cools down faster than water Specific Heat Some things heat up or cool down faster than others. Land heats up and cools down faster than water

Why does water have such a high specific heat? water metal Water molecules form strong bonds with each other; therefore it takes more heat energy to break them. Metals have weak bonds and do not need as much energy to break them.

Heat Transfers Conduction- heat transferred through direct touch Convection- heat transferred through the movement of currents in a fluid Radiation- heat transferred through electromagnetic waves

Heat Transfers

Conductors and Insulators Conductor- transfers thermal energy well Ex: metals Insulators- transfers thermal energy very poorly Ex: Wood, paper, plastic, gases in the air

Changes in State of Matter Depends on how much thermal energy Vaporization- matter changes from liquid to a gas Evaporation- vaporization at the surface Boiling- vaporization below the surface Melting- solid to liquid Freezing- liquid to solid Condensation- gas to liquid
