temperature

Question 1

conduction

Answer 1

heat transfer through direct contact (e.g., metal rod)

Question 2

convection

Answer 2

heat transfer through fluid (e.g., boiling water)

Question 3

radiation

Answer 3

heat transfer through electromagnetic waves (e.g., sunlight

Question 4

thermal equilibrium

Answer 4

• two objects in contact can no longer transfer heat between them
• same temperature
