Topic: Electricity, Heat and Matter
This topic focuses on the conservation of matter and the processes of energy transfer and transformation, especially as they relate to heat and electrical energy.
This topic focuses on the conservation of matter and the processes of energy transfer and transformation, especially as they relate to heat and electrical energy.
- The total amount of matter is conserved when it undergoes a change.
- Energy can be transformed from one form to another or can be transferred from one location to another.
1. Define temperature as the measure of thermal energy and describe the way it is measured.
|
Thermal energy, or heat, is the energy of moving particles in an object. Temperature is the measure of thermal energy. It measures how fast particles are moving in matter.
Know the difference: - heat is energy - temperature is a measure of thermal energy The more heat, the faster the particles move. Cold things have slow-moving molecules, while hot things have fast-moving molecules. The most common tool for measuring thermal energy (heat) is a thermometer.
|
2. Trace how thermal energy can transfer from one object to another by conduction.
|
Heat always flows from a warmer object to a cooler one. When things that are at different temperatures touch each other, heat energy moves from the hotter thing to the colder thing. Conduction is when thermal energy is transferred from one solid object to another solid object through direct touching. An example is the heat in a cookie sheet moving up through the pan into the cookies.

3. Describe that electrical current in a circuit can produce thermal energy, light, sound and/or magnetic forces.
|
Electrical current in a circuit can produce thermal energy, light, sound, and/or magnetic forces. These energies can transform from one form of energy into another.
|
4. Trace how electrical current travels by creating a simple electric circuit that will light a bulb.
|
Electric current is the movement of electrons through a conducting material. For an electric current to happen, there must be a circuit. A circuit is a closed path or loop around which an electric current flows.
