Understand heat transfer through conduction, convection, and radiation, and how temperature differs from heat.
Heat is a form of energy that flows from hot to cold objects. Temperature measures how hot or cold something is.
Why can a small cup of boiling water have less total heat than a large tub of warm water, even though it's hotter?
Heat depends on both temperature and the amount of matter, so a larger mass at a lower temperature can still contain more total heat energy
What instrument measures temperature?
A thermometer
Conduction transfers heat through direct contact (mostly in solids). Convection transfers heat through fluid movement (liquids/gases). Radiation transfers heat through electromagnetic waves, even through a vacuum.
How does heat travel from the sun to Earth through the vacuum of space?
By radiation, which doesn't require a medium
Why does a metal spoon in hot soup become warm at the handle end?
Heat travels through the metal by conduction, transferring energy from particle to particle
