heat energy

convection conduction

transfer of heat by direct contact between particles conduction
transfer of heat into liquids and gasses through currents convection
transfer of heat by electromagnetic waves radiation
a metal spoon gets hot in boiling water conduction
a egg on a frying pan sizzles when it cooks conduction
a ice cube in a hand begins to melt conduction
a metal cup gets hot when boiling water is poured in it conduction
cool air sinks to the ground on a warm night convection
air is warmer near the cielling than the floor convection
toes are warmer in front of a space heater radiation
the sun melts a icey lawn radiation
is the sun the source of all of our energy yes
what are the three types of heat transfers conduction,convection and radiation
radiation is the heat transfer by... electromagnetic waves
conduction transfers heat by... direct contact
convection transfers heat by... lquids and gasses through currents
conduction is the direct transfer of heat when molecuels... bump into each other
as cold air becomes more dense itpushes up warmer air creating a... convection current
most radiation from earths surface is assorbed and... heats up our atmaspheree
the sun is the source of... all our energy in our atmasphere
