Fun Fact 2: Everything in our universe is made up of tiny atoms. So many
that just one pin head is made up of millions of atoms. When an object
moves it produces kinetic energy as the atoms are moving. Kinetic energy
is required for heat to be produced; the atoms must be in motion to
transfer the heat from one particle to another.
Fun Fact 3: Thermal energy is also known as heat energy. Thermal heat is
transferred between particles. When particles begin to heat up, they
start to move more quickly making them vibrate and break bonds between
particles. This is when thermal energy is transferred from one atom to
Fun Fact 4: There are three main ways in which thermal energy is
transferred: conduction, convection and radiation. As you have so far
discovered; the Sun is a good example of radiation.
Fun Fact 5: The Earth absorbs thermal heat from the Sun as radiation
travels through electromagnetic waves and produces radiant energy.
Fun Fact 6: What is Convection? The definition or description of
convection can be explained in this simple way; when thermal energy is
transferred between moving gas or liquid particles.
Fun Fact 7: What is Conduction? The definition or description of
conduction can be explained in this simple way; the transfer of thermal
energy between matters of different temperature. For example, if you put
a cold object with a warm object. The warmth will be passed to the cold
object through conduction. Conduction continues until both objects reach
the same temperature.
Fun Fact 8: If you pick up something hot, such as a hot potato, it might
be so hot that it scalds you - this is because thermal heat is
transferred from the potato to your skin
Fun Fact 9: If you make a cup of hot chocolate and pour cold milk into
it. The hot chocolate will cool down because thermal heat is transferred
from the hot liquid to the cool liquid.
Fun Fact 10: Thermal heat can change the state of particles - changing
them to gas, liquid or solid form. Different things happen when
temperature increases or decreases (goes up and down). For example,
water freezes at 0 degrees Celsius and it boils at 100 degrees Celsius.
Fun Fact 11: The amount of time it takes to heat something (e.g. water)
depends on how much water there is. It takes much longer to heat a whole
swimming pool of water than it does to heat a kettle of water.
Fun Fact 12: Thermal energy can cause liquid to change to gas. This is
known as vaporization. A good example of this is when thermal energy
causes droplets of water to evaporate/vaporize across the sea to form
Fun Fact 13: Thermal energy can cause gas to liquefy. Condensation is a
good example of this. Sometimes condensation can appear on windows,
especially in the bathroom when vapour changes to liquid water.
Fun Fact 14: Thermal energy can cause liquid to solidify; this happen
when water reaches freezing point and turns to ice.
Fun Fact 15: Thermal energy can cause a solid to melt. The melting
process occurs when a solid (such as ice), changes to a liquid (water).
