Front

Temperature is _________________

Back

a measure of the average kinetic energy of all the particles in an object/substance.

Front

What is the formula for density?

Back

density = mass / volume

Front

Explain the heat transfer when holding hands with a friend whose hands are warmer than yours.

Back

The heat energy from your friend's hand transferred to your hand through conduction.

Front

What is used to measure (but not precise), heat, and mix large amounts of liquids?

Back

beaker

Front

The temperature and phase can change at the same time. True or False?

Back

False

Front

What is the definition of density?

Back

Density is the mass of an object divided by its volume.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is the relationship between temperature and kinetic energy?

Back

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

Front

What is the unit of measurement for temperature?

Back

Celsius (°C) or Kelvin (K).
