Explanation:

1. When hot coffee is stirred with a spoon, heat transfer from the hot coffee to the spoon occurs through direct contact, which is conduction.
2. A chair placed several feet from a fire in a fireplace with a glass - screen gets warm on the side facing the fire because heat is transferred in the form of electromagnetic waves (infra - red radiation) from the fire to the chair, which is radiation.
3. In a decorative lamp with colored liquids, the globes rise because the heated liquid at the bottom becomes less dense than the cooler liquid above it, causing it to rise, which is convection.

Answer:

Question 1: Conduction
Question 2: Radiation
Question 3: Convection
