Question 1 (5 points) Explain how equilibrium is reached between 2 objects of different temperatures. Question 2 (5 points) What happens to an object when it gains heat energy? What happens to an object when it loses heat energy? Question 3 (5 points) Conduction: Explain the difference between the two types of conduction Question 4 (5 points) Convection: Why are solids not able to transfer heat through convection? Question 5 (5 points) Radiation: Explain why every object radiates heat energy (both a fire and an ice cube radiate heat energy!)
