An example of Convection
If two glasses of water are at the same temperature,
the average KINETIC energy of the particles of water in each glass is the same.
When THERMAL energy is transferred from one object to another...
the temperature of the object giving off heat decreases
How does a thermometer work?
A liquid, often mercury or alcohol, is sealed in a long, thin glass tube. As the liquid is heated, the particles speed up and spread out. When the particles spread out, the liquid takes up more volume, and so it expands and rises in the tube. When the liquid cools, the particles come closer together, causing the liqid to contract and flow down the tube.
The reason that placing a jar under warm running water helps to loosen the lid on the jar?
An example of conduction
When one end of an iron nail is held in a flame, the energy is transmitted along the nail
