Question

part a - vocabulary
term definition

1. heat a. heat transfer by electromagnetic waves
2. temperature b. heat transfer by movement of fluids (liquids/gases)
3. conduction c. the transfer of thermal energy from warmer to cooler objects
4. convection d. heat transfer through direct contact
5. radiation e. the average kinetic energy of particles in a substance

part b - multiple choice
circle the correct answer.

1. which type of heat transfer occurs when you touch a hot metal pan?

a) conduction b) convection c) radiation d) evaporation

1. when boiling water, heat moves throughout the pot mainly by:

a) radiation b) convection c) conduction d) reflection

1. the sun warms the earth through:

a) convection b) conduction c) radiation d) conduction an

Explanation:

• For Part A:
• Heat: Heat is the transfer of thermal energy from warmer to cooler objects. So, 1 - c.
• Temperature: Temperature is the average kinetic energy of particles in a substance. So, 2 - e.
• Conduction: Conduction is heat transfer through direct contact. So, 3 - d.
• Convection: Convection is heat transfer by movement of fluids (liquids/gases). So, 4 - b.
• Radiation: Radiation is heat transfer by electromagnetic waves. So, 5 - a.
• For Part B:
• Question 1: When you touch a hot metal pan, heat transfer occurs through direct contact (conduction).
• Question 2: When boiling water, heat moves throughout the pot mainly by the movement of the fluid (water), which is convection.
• Question 3: The Sun warms the Earth through electromagnetic waves (radiation) as there is no direct contact (conduction is out) and no fluid movement (convection is out) in the vacuum - like space between the Sun and the Earth.

5. a

Part B
