11.1 What is heat? Heat is thermal energy that is moving. Heat flows any time there is a difference in temperature. Because your hand has more thermal energy than chocolate, thermal energy flows from your hand to the chocolate and the chocolate begins to melt.

11.1 What is heat? Heat and temperature are related, but are not the same thing. HEAT is thermal energy that is moving or is capable of moving TEMPERATURE is how much kinetic energy the molecules have due to random motion The amount of thermal energy depends on the temperature but it also depends on the amount of matter you have. The metric unit for measuring heat is the joule. This is the same joule used to measure all forms of energy, not just heat.

11.1 Specific heat The specific heat is a property of a substance that tells us how much heat is needed to raise the temperature of one kilogram of a material by one degree Celsius. Knowing the specific heat of a material tells you how quickly the temperature will change as it gains or loses energy.

11.1 Why is specific heat different for different materials? Temperature measures the average kinetic energy per particle. Energy that is divided between fewer particles means more energy per particle, and therefore more temperature change. In general, materials made up of heavy atoms or molecules have low specific heat compared with materials made up of lighter ones.

Simulation – specific heat Select show energy Drag and drop Drag and hold heat or cool

11.2 Heat transfer Heat conduction is the transfer of heat by the direct contact of particles of matter. Conduction occurs between two materials at different temperatures when they are touching each other. Where is the heat energy conducted to and from in this system?

11.2 Convection Convection is the transfer of heat through the motion of matter such as air and water. The hot water at the bottom of the pot rises to the top and replaces the cold water.

11.2 Thermal radiation Heat from the Sun is transferred to Earth by thermal radiation. All the energy the Earth receives from the Sun comes from thermal radiation. The higher the temperature of an object, the more thermal radiation it emits.

11.2 Thermal radiation Thermal radiation is also absorbed by objects. The amount of thermal radiation absorbed depends on the surface of a material. Dark surfaces absorb most of the thermal radiation they receive. Silver or mirrored surfaces reflect thermal radiation.

11.2 Heat transfer, winds, and currents A thermal is a convection current in the atmosphere. When a surface, like a road absorbs solar radiation, it emits energy as heat. The warmed air molecules gain kinetic energy and rise. Colder air is forced aside and sinks.
