Front

What is the unit heat is measured in?

Back

Calorie

Front

Which particle has more kinetic energy before collision: Fast Particle A or Slow Particle B?

Back

Fast Particle A

Front

If a student heated 50mL of water from 0℃ to 60℃, how much energy did she use? (Use the formula: cal = mass (times) △T)

Back

3000 calories

Front

What happens to kinetic energy when Fast Particle A and Slow Particle B collide?

Back

Energy transfers to B

Front

What is energy transfer by collision called?

Back

Conduction

Front

Define kinetic energy.

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is the formula for calculating heat energy?

Back

cal = mass (times) △T

Front

What does △T represent in the heat energy formula?

Back

△T represents the change in temperature.

Front

What is conduction?

Back

Conduction is the transfer of heat energy through collisions between particles.

Front

How does temperature affect kinetic energy?

Back

As temperature increases, the kinetic energy of particles also increases.
