Differentiating Temperature and Heat

This video tutorial by Mr. Millings explains the differences between temperature and heat. Temperature is defined as a measure of the average kinetic energy of particles in a substance, indicating how fast they move. The video uses simulations to show how temperature changes affect particle motion and kinetic energy. It also clarifies that heat is the flow of energy due to temperature differences between objects, always moving from hot to cold. The tutorial includes practical examples and simulations to illustrate these concepts, emphasizing the distinction between temperature and heat.

What does temperature measure in a substance?

• The mass of the substance

• The average kinetic energy of particles

• The total energy of all particles

• The potential energy of particles

In the Styrofoam container example, what happens to the temperatures of the hot and cold water over time?

• The hot water gets hotter and the cold water gets colder

• Both temperatures remain the same

• The temperatures level off and become equal

• The hot water evaporates and the cold water freezes

What is the final outcome when two objects of different temperatures are left to interact over time?

• No change in temperatures

• Both objects reach the same temperature

• The colder object gets colder

• The hotter object gets hotter
