... a difference in temperature between two places then heat will flow between them. Also, heat energy causes the molecules to move faster. But there are three ways that the beaker can be affected by heat. CONDUCTION of heat is a process where vibrating particles pass on their extra vibration energy to the particles near them. Metals are good conductors because they have free electrons that will pass the heat on and diffuse quickly through the metal. Non metals are good insulators. CONVECTION only happens in liquids and gases. This is because the particles in solids do not move. Convection happens when more energetic particles move from the hotter area to the cooler part and take their energy with them. RADIATION is electromagnetic waves of a certain frequency. An object will emit or /and absorb radiation. The hotter they are the more heat radiation they emit. Cooler objects around them absorb the emissions. Another way ...
