Thermal Energy and Heat Temperature, Thermal Energy, and Heat The Transfer of Heat Thermal Energy and States of Matter Uses of Heat Table of Contents

Thermal Energy and Heat Temperature, Thermal Energy and Heat Temperature Temperature is a measure of the average kinetic energy of the individual particles in matter.

Thermal Energy and Heat Temperature, Thermal Energy and Heat Temperature Temperature changes cause the level of the liquid inside a thermometer to rise and fall.

Thermal Energy and Heat Temperature, Thermal Energy and Heat The three common scales for measuring temperature are the Fahrenheit, Celsius, and Kelvin scales. Temperature Scales

Thermal Energy and Heat Specific Heat The specific heat of three different materials was measured. These data are shown in the graph. Temperature, Thermal Energy and Heat

Specific Heat Water, sand, and iron Reading Graphs: What three materials are compared in the graph? Temperature, Thermal Energy and Heat

Specific Heat About 4,200 J would be required Interpreting Data: About how much heat is required to raise 1 kg of water by 1 K? Temperature, Thermal Energy and Heat

Specific Heat Sand Drawing Conclusions: According to the graph, which material requires more heat to raise its temperature by 1 K, iron or sand? Temperature, Thermal Energy and Heat

Temperature, Thermal Energy and Heat Specific Heat A material with a high specific heat can absorb a great deal of thermal energy without a great change in temperature.

Thermal Energy and Heat Energy Measured Units Comparing and Contrasting As you read, compare and contrast temperature, thermal energy, and heat by completing a table like the one below. Temperature Average kinetic energy of particles Fahrenheit or Celsius degrees, kelvins Thermal Energy Total energy of all particles in an object Joules HeatEnergy transferredJoules Temperature, Thermal Energy and Heat

Thermal Energy and Heat - The Transfer of Heat Heat Moves One Way If two objects have different temperatures, heat will flow from the warmer object to the colder one.

Thermal Energy and Heat - The Transfer of Heat Insulators Air between the panes of this window acts as an insulator to slow the transfer of heat.

Thermal Energy and Heat Main Idea Detail Identifying Main Ideas As you read the section “How Is Heat Transferred?,” write the main idea in a graphic organizer like the one below. Then write three supporting details that further explain the main idea. Heat can be transferred in three ways. Conduction– transfer of heat between particles without the movement of matter Convection– transfer of heat by the movement of currents in a fluid Radiation– transfer of energy by electromagnetic waves - The Transfer of Heat
