HW 1: Temperature and Heat

What happens to the temperature of water when it has less volume and is heated?

• It heats up slower than more voluminous water.

• It does not change temperature.

• It heats up faster than more voluminous water.

• It cools down.

Solids contain no kinetic energy.

• True

• False

What is thermal energy?

• The average kinetic energy of particles.

• The total kinetic energy of all particles in a substance.

• The potential energy in a substance.

• The heat transferred from one object to another.

How is temperature different from thermal energy?

• Temperature is the total kinetic energy, while thermal energy is the average.

• Temperature and thermal energy are the same.

• Temperature is the average kinetic energy, while thermal energy is the total.

• Temperature is only relevant in gases.

Which method of thermal energy transfer involves movement of the matter itself?

• Convection

• Radiation

• None of the above

• Conduction

What is the primary way that heat from the Sun reaches the Earth?

• Radiation

• It does not reach Earth

• Convection

• Conduction
