Grade 6 - Heat Conduction

AB
heatthe motion of atoms and molecules, also called kinetic energy
more heat energy in a solid, liquid or gas is produced byincreased motion of atoms and molecules
energy transferwhen molecules come in contact
conductiona kind of energy transfer that happens when atoms come in contact
heat conductionoccurs when two materials touch each other. The motion of the atoms and molecules in the warmer material is transferred to atoms and molecules in the cooler material, making those atoms and molecules move faster.
how heat transfers from one material to another (conduction)Material can absorbs radiant energy (light, infrared, ultraviolet) from a radiant source, such as the Sun.This absorbed energy increases the molecular activity in that material. The motion of the atoms and molecules in a warmer material is transferred to atoms and molecules in the cooler material it touches.
heat transfer by conduction from atom to atom in a material can only happenwhen their atoms and molecules make contact
why a canned beverage from a refrigerator feel coldThe atoms and moleclules in the can and in the beverage have less energy (motion) than the atoms and molecules in your hand. Heat transfers from your hand to the soda can by conduction. The molecules in your hand lose energy and move slower. Your hand senses the loss of heat as cold
