Essential Questions What is the difference between heat

Essential Questions: • • What is the difference between heat and temperature? What happens to thermal energy of a substance during a physical change of state?

• Heat is the total energy of molecular motion in a substance. Heat energy depends on the speed of the particles, the number of particles (the size or mass), and the type of particles in an object. What is the difference between heat and temperature?

• Temperature is a measure of the average energy of molecular motion in a substance. Temperature does not depend on the size or type of object. What is the difference between heat and temperature?

Temperature is not energy, but a measure of it. Heat is energy. What is the difference between heat and temperature?

Which object contains the most heat, a boiling pot of water or a gigantic iceberg? What is the difference between heat and temperature?

Temp Heat • Although the boiling water has a relatively high temperature, it contains relatively little heat energy. • While the iceberg is relatively cold (low temperature) it contains an enormous amount of heat energy relative to the boiling water in the tea pot. What is the difference between heat and temperature? Temp Heat
