Exploring Heat Transfer Concepts

What prevents the paper cup filled with water from burning?

• The water absorbs and distributes the heat.

• The cup is double-layered.

• The cup is made of a special material.

• The cup is treated with a flame retardant.

What happens to the thermal energy in the copper rod experiment?

• It only affects the rod and not the chocolate.

• It remains constant throughout the rod.

• It causes the chocolate to melt as it transfers.

• It decreases as it moves along the rod.

Why does the thinner copper rod melt the chocolate faster?

• It is less dense than the thicker rod.

• It conducts heat more efficiently due to fewer atoms.

• It has a higher melting point.

• It absorbs less heat from the environment.

How does radiation differ from conduction and convection?

• It requires physical contact to transfer heat.

• It cannot transfer energy through empty space.

• It transfers energy through waves.

• It involves the circulation of fluids.

What is the role of emergency blankets in thermal energy management?

• They reflect radiation back to the body.

• They absorb external heat sources.

• They prevent convection currents.

• They conduct heat away from the body.

How does a solar cooker use radiation to heat food?

• By increasing the food's density

• By conducting heat from the sun

• By circulating hot air around the food

• By reflecting radiation onto the food

What effect does the water have inside the balloon in the final demonstration?

• It absorbs heat, preventing the latex from melting.

• It increases the internal pressure of the balloon.

• It reacts chemically with the latex.

• It causes the balloon to float.
