Fun Facts on Heat Energy

Fun Facts For Kids

Did You Know?
Did you know that Heat Energy produced by the Sun is transferred to Earth by radiation? Did you know that Heat Energy causes water to evaporate, condense, melt and freeze? Our fun facts sheets provide definitions and examples of processes and occurrences caused by heat.

Fun Fact 1: The Earth absorbs heat energy which is transferred from the Sun through radiation. The Sun might be millions of kilometres from the Earth but it does control the temperature of our planet.

Fun Fact 2: Our entire universe is made up from tiny particles known as atoms. Kinetic energy is produced when an object moves (when the atoms move). The atoms transfer heat when they move.

Fun Fact 3: Heat Energy is also known as thermal energy. This type of energy is transferred from particle to particle which move quicker with the production of more energy. The quick movement causes bonds to break and heat energy to transfer from one atom to another.

Fun Fact 4: Heat Energy is transferred in three main ways: conduction, convection and radiation.

Fun Fact 5: Definition of radiation: radiation from the Sun travels through electromagnetic waves and produces radiant energy. The Earth absorbs the radiant energy which increased its temperature.

Fun Fact 6: Definition of convection: when Heat Energy is transferred between moving gas or liquid particles.

Fun Fact 7: Definition of conduction: when Heat Energy is transferred between particles which are different in temperature. E.g. if you place a cold and warm object together, heat will pass from the warm object to the cold object through conduction. Conduction will continue until both objects achieve the same temperature.

Fun Fact 8: Example: If you pour cold milk into a bowl of steaming hot porridge, the porridge will cool down. This is because thermal heat is transferred from the hot liquid to the cool liquid.

Fun Fact 9: Example: If you try to pick up something which is hot, such as a metal spoon which has been left in a cup of boiling water, it can be so hot that it burns your fingers - this is because thermal heat is transferred from the metal spoon to your fingers.

Fun Fact 10: Heat energy can transform particles from gas, liquid to solid form. Various occurrences take place when temperatures go up and down. E.g. water will freeze at 0 degrees Celsius and it will boil at 100 degrees Celsius.

Fun Fact 11: Example: It takes a longer amount of time to heat a swimming pool of water than kettle of water. The more liquid there is, the longer it will take to heat.

Fun Fact 12: Heat Energy can transform liquid into gas state. This is known as evaporation or vaporization. Water can evaporate with heat.

Fun Fact 13: Heat Energy can transform gas state to liquid forming condensation - e.g. in the bathroom, vapour can change to liquid.

Fun Fact 14: Heat Energy can transform liquid into a solid when it is reduced. For example, when water reaches freezing point it turns into ice.

Fun Fact 15: Heat Energy causes melting. A solid such as ice will begin the melting process when it starts to absorb heat energy; the ice reacts by changing to a liquid (water).
