1. MCQ: How does heat move in liquids and gases? a) Through conduction b) Through radiation c) Through convection d) Through evaporation

Correct answer: c) Through convection

1. True or False: Heat can only move in one direction in liquids and gases. Correct answer: False

2. Fill in the blank: Heat moves from areas of ____ temperature to areas of ____ temperature. Correct answer: higher, lower

3. Short answer: Explain how heat moves in liquids and gases. Correct answer: Heat moves in liquids and gases through convection. This means that when a liquid or gas is heated, the particles gain energy and move faster. The faster-moving particles then spread the heat to other particles by colliding with them. This process continues, creating a flow of heat throughout the liquid or gas.

4. Multiple response: Which of the following are examples of convection? a) Boiling water in a pot b) Warm air rising and cool air sinking c) Heat transfer through a metal spoon d) Steam rising from a cup of hot tea

Correct answers: a) Boiling water in a pot and b) Warm air rising and cool air sinking

Correct answer: c) Convection

1. True or False: Heat can only move in liquids and gases when they are in motion. Correct answer: True

2. Fill in the blank: In convection, heat is transferred through the movement of ____. Correct answer: fluids
