Heating And Cooling Flashcards
Is heat measured in joules or *c ?
Joules
What ins the difference between heat and tempature ?
Heat is a form of energy and tempature is the energy per particle
What is conduction ?
How energy is transferred through a solid
What is a conductor ?
A material that let’s heat pass through
What is an insulator ?
A material that slows down the rate at which heat passes through it .
What are convection currents ?
A circular movement of hot gases and fluids rising and cold gases and fluids falling
What happens when solid reaches boiling point ?
Energy is used to break particles bonds
What is radiation ?
How energy travels without particles
What is infrared radiation ?
Carries thermal energy from a hotter object to a cooler one
Why do marathon runners wrap themselves in foil ?
Because the foil reflects their body heat so they don’t cool down too quickly
What is evaporation ?
