Thermal Energy and Specific Heat

Mr. Anderson's video on heat exchange explains how energy is transferred as heat between objects of different temperatures. The video covers the concept of kinetic energy, the role of molecular motion, and how different materials transfer heat. A simulation demonstrates these principles, highlighting the differences in heat transfer among iron, brick, and water. The concept of specific heat capacity is introduced, explaining how it affects the rate of temperature change in various substances.

What happens when a warmer body comes into contact with a colder body?

• No energy transfer occurs.

• The colder body transfers energy to the warmer body.

• The warmer body transfers energy to the colder body.

• Both bodies lose energy to the environment.

Why is heat not found on the periodic table?

• Because it is a type of metal.

• Because it is a type of liquid.

• Because it is a type of gas.

• Because it is not a substance, but a transfer of energy.

Which material is likely to transfer heat more readily?

• Plastic

• Iron

• Brick

• Wood

What is observed when energy is added to a substance in the simulation?

• The substance changes state.

• The substance's temperature decreases.

• The substance's temperature remains constant.

• The substance's temperature increases.

What is the result when a hot object is placed in water?

• The hot object transfers energy to the water.

• The hot object absorbs energy from the water.

• No energy transfer occurs.

• The water's temperature decreases.

What does the Maxwell-Boltzmann distribution illustrate?

• The distribution of temperature in a room.

• The distribution of kinetic energy among particles in a substance.

• The distribution of mass in a substance.

• The distribution of energy in a single molecule.

What happens when two bodies reach thermal equilibrium?

• They have the same average kinetic energy.

• The warmer body continues to transfer energy.

• The colder body starts transferring energy.

• They have different average kinetic energies.

What does specific heat capacity measure?

• The amount of energy a substance can release before changing temperature.

• The amount of energy a substance can release before changing state.

• The amount of energy a substance can absorb before changing temperature.

• The amount of energy a substance can absorb before changing state.

Which substance has a higher specific heat capacity?

• Iron

• Water

• Aluminum

• Gold

What is the unit of specific heat capacity?

• Joules per liter per Kelvin

• Joules per kilogram per Kelvin

• Joules per mole per Kelvin

• Joules per gram per Kelvin
