Answer:
Convection
Explanation:
Hot water will rise due to heat transfer by convection occurring in the heating system.
- When a fluid is heated, the molecules will gain thermal energy.
- As the thermal energy of the liquid increases, the molecules will have heat which is average kinetic energy in the system.
- This causes them to be less denser and they rise in the cooking medium.
- As they rise, the colder part of the water sinks down to replace them in the pot.
- This exchange sets up convection cells in the heating medium.
