Thermal Energy and Heat test
conduction- is the transfer of energy as heat from one substance to another through direct contact
occurs any time that objects with different temperatures come in contact with each other
hot tea to hands
ice cube in a glass of water
Teperature- is the average kinetic energy particles
Themal energy- is the total kinetic energy of all particles in a substance
is measured in joules
heat- is the energy transferred from an object at a higher temperature to an object with a lower temperature
heat is measured in calorie and joules
conductors-is a material that transfers heat very well
wood
plastic
paper
insulators- is a material that is a poor conductor of heat
pots with metal handles
metal
convection- Is the transfer of energy as heat by the movement of a liquid or gas
occurs when a cooler, denser mass of a gas or liquid replaces a warmer, less dense mass of a gas or liquid by pushing it upward
particles move closer together, making the water denser
pot of boiling water
tea pot heating up
radiation- Is the transfer of energy by electromagnetic waves
emitted from one object and then absorbed by another
can travel through empty space
sun
light
fire
