Question 1 · 1 mark · Difficulty 1/3

In an exothermic reaction, energy is:

  1. Transferred to the surroundings
  2. Taken in from the surroundings
  3. Destroyed
  4. Created
Show answer & explanation
✓ Answer: ATransferred to the surroundings
Exothermic reactions transfer energy to the surroundings, usually as heat, so the temperature of the surroundings rises.
Question 2 · 1 mark · Difficulty 1/3

In an endothermic reaction, the temperature of the surroundings:

  1. Decreases
  2. Increases
  3. Stays exactly the same
  4. Doubles
Show answer & explanation
✓ Answer: ADecreases
Endothermic reactions take in energy from the surroundings, so the surrounding temperature decreases.
