Cooling Methods for Chocolate Drink

What is the primary goal when trying to cool a hot chocolate drink?

• To maintain its current temperature

• To gain heat from the surrounding air

• To increase its temperature

• To lose heat to the cooler surrounding air

Why is covering the glass with a metal lid not effective in cooling the drink quickly?

• The metal lid absorbs heat

• The lid allows heat to escape too quickly

• The trapped air under the lid is a poor conductor of heat

• The lid increases the drink's temperature

How does replacing the glass with a metal cup help in cooling the drink faster?

• Metal is a poorer conductor of heat than glass

• Metal is a better conductor of heat than glass

• Metal prevents heat from escaping

• Metal absorbs the drink's heat

What effect does wrapping a dry towel around the glass have on the cooling process?

• It slows down the cooling process due to trapped air

• It makes the drink hotter

• It has no effect on the cooling process

• It speeds up the cooling process

Why does stirring the drink with a wooden spoon help it cool faster?

• It prevents the drink from losing heat

• It decreases the exposed surface area

• It increases the exposed surface area and allows hot liquid to rise

• It traps heat inside the drink
