How Does Mass Affect Temperature Change?

What happens to the temperature of a substance when heat is added?

• It decreases

• It stays the same

• It increases

• It turns into mass

Which factor affects how quickly a substance changes temperature?

• Mass

• Color

• Shape

• Smell

What type of heat transfer occurs when a metal spoon gets hot after being left in a pot of boiling soup?

• Conduction

• Convection

• Radiation

• Evaporation

If you heat 100g of water and 500g of water for the same time, which will have the smallest temperature change?

• 100g of water

• 500g of water

• Both will have the same temperature change

• It depends on the shape of the container

Which of the following best describes convection?

• Heat transfer through direct contact

• Heat transfer through movement of fluids or gases

• Heat transfer through electromagnetic waves

• Heat transfer without energy

What is an example of radiation heat transfer?

• A metal rod heating up when placed in fire

• Boiling water circulating in a pot

• The Sun warming your skin

• A hot air balloon rising

A swimming pool takes longer to warm up than a small bucket of water because:

• The bucket absorbs more sunlight

• The pool has a greater mass and needs more heat energy

• The bucket reflects heat

• The pool's water is already cold

Which material is the best conductor of heat?

• Plastic

• Wood

• Copper

• Air

Why do dark-colored objects heat up faster in sunlight?

• They conduct heat better

• They reflect most of the radiation

• They absorb more radiation energy

• They contain more mass

If a pot of water is heated from below, what happens to the warmer water?

• It stays at the bottom

• It rises while cooler water sinks

• It mixes evenly without movement

• It disappears
