Chapter 6: Thermal Energy

Section 1: Temperature and Heat

Temperature Effect on Atomic Movement What happens to the speed of atoms and molecules when temperature is increased or decreased? At this site, you command the temperature and the computer shows you the rest. 

Defining Temperature (02:01) Heat and temperature are related, but don't mean the same thing; temperature is used to measure how hot or cold an object is; Heat is energy and is determined by the temperature and amount of a substance; a thermometer measures temperature by the fluid inside it either expanding or contracting according to the energy of its molecules.

Thermal Equilibrium (02:16) The transfer of heat energy at the molecular level is discussed using cold water added to hot tea; thermal equilibrium is discussed; heat involves the transfer of thermal energy-due to temperature difference-between objects.

Chemistry Connections: Specific Heat Capacity and Calorimetry (29:06)Specific heat capacity is explained and Joule's experiment is duplicated to show how he determined the Specific heat capacity of water. Experiments demonstrate that the heat released by one substance equals the heat absorbed by another. Students see that when this applied to calorimetry, the Specific heat of different substances can be determined.

Section 2: Transferring Thermal Energy

Thermal Conductance (01:37) Conduction is the only way thermal energy transfers in a solid. Conduction properties of solids vary; properties of conductors and insulators are presented.

Transferring Thermal Energy: Radiation (00:52) The transfer of heat by radiation does not require particles for energy transfer. Greenhouses trap radiant heat.

Transferring Thermal Energy: Conduction (00:55) The transfer of heat by conduction occurs in solids, liquids, and gases.

Transferring Thermal Energy: Convection (01:03) The transfer of heat by convection occurs only in liquids and gases. Convection currents are responsible for weather.
