Temperature
Heat
If you heat a solid, the particles in the solid vibrate more
-
-
Temperature is a measure of how hot something is, measured in degrees Celsius.
-
Energy
cannot appear or disappear, but can be rransferred ( law of conservation of energy)
-
Conduction
Metals like copper are verry good thermal conductors, transfer energy through solids
conductor and insulator
energy transfer good-conductor(metal-copper) , bad-insulator(paper, cloth, wood)
-
The left end ofthe bar is hot and the right end ofthe bar is cold, so energy is transferred from the left to the right. Electrons also transfer energy in metals.
radiation
Radiation, including light and infrared, is emitted by the Sun.

-
Convection
Energy is transferred through the pan to the water at the bottom of the pan by conduction. This is because the bottom of the pan is solid.

• Cooler, denser water moves down to take its place.
water in the pan is circulating up and down. The circulation
of water that is set up in this way is called a convection current
