Bill Nye Heat

What is the primary way heat is transferred from the griddle to the pancake batter?

• Convection

• Conduction

• Radiation

• Insulation

Which method of heat transfer involves the movement of heat through fluids?

• Compression

• Conduction

• Radiation

• Convection

What does the experiment with a metal knife, a plastic knife, and a Popsicle stick demonstrate?

• Insulation properties

• Conduction efficiency

• Radiation effects

• Convection currents

What natural phenomenon was demonstrated using a glider flight?

• Natural convection currents

• Insulation by the atmosphere

• Conduction of heat from land

• Radiation from the sun

How does a thermos prevent heat transfer?

• By conduction

• Using radiation

• Through convection

• Using a vacuum

Why does hot tea in a thermos stay hot?

• Due to the vacuum preventing heat loss through conduction

• Because the thermos is always sealed tightly

• Because the tea generates more heat over time

• The thermos material heats up the tea

What demonstrates the concept of heat radiation?

• A plastic bottle cap

• A cold tea bottle warming up

• A metal pan baking brownies

• A fire radiating heat

Why do brownies in a glass pan cook differently than in a metal pan?

• Glass pans cook brownies faster

• Metal pans reflect infrared light, affecting cooking time

• Metal pans are better conductors of heat

• Glass pans are usually thicker

How do clothes help to keep us warm?

• By absorbing sunlight

• By increasing body temperature

• By trapping air which acts as an insulator

• By generating heat

What is the role of a heat pump in a building?

• To insulate the building from cold

• To pump water through the heating system

• To generate heat by burning fuel

• To transfer heat from inside to outside or vice versa
