Term | Definition |
---|---|
heat | The movement of thermal energy from the area of higher temperature form an area of lower temperature. |
thermal energy | Both the potential and kinetic energy of particles |
temperature | Temperature is defined as a measure of the average kinetic energy of all of the particles in a substance |
conductor | Materials that allow thermal energy to flow easily through it. |
insulator | Materials that slow down the flow of thermal energy transfer through it. |
thermal expansion | As the thermal energy of a substance increases, its particles spread out and the substance expands. The expanding of matter when it is heated. |
thermal equilibrium | when the temperatures of materials that are in contact are the same. Objects become the same temperature. |
The difference between a conductor and an insulator | Conductors allow thermal energy to flow easily. Insulators slow down the flow of thermal energy. |
Examples of conductors and insulators | A few examples of a conductor are silver, aluminium, and iron. A few examples of an insulator are paper, wood, and rubber. Electrons move freely within the conductor. Electrons do not move freely within the insulator. |
How does thermal energy affect particle motion? (solid, liquid, gasses) | A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. |
What is dependent variable vs independent variable? | Dependent variable is the y axis which is going up and the independent variable is the x axis going across. |
