Lesson details
Key learning points
- The higher the temperature of a hot drink, the faster its particles are moving.
- A hot drink makes the particles in the air around it move more quickly.
- The particles of a hot drink begin to move less quickly as they transfer energy to the air particles.
- The greater the temperature difference between a hot drink and the air, the faster it cools down.
Keywords
Surroundings - the space around an object
Cooling rate - how quickly the temperature of an object falls
Cooling curve - a line graph that shows how a cooling object’s temperature changes with time
Energy - a solid object has energy in its thermal store because its particles are vibrating
Dissipate - to spread out
Common misconception
The energy of hot objects disappears (is destroyed) as they cool.
Placing a cup of hot water into a surrounding bowl of cold water that is warmed without the waters mixing demonstrates how surroundings are heated as energy is dissipated.
