Question

A 1 kg block of ice at −10°C is heated uniformly. The temperature-time graph shows:
  1. A
    Straight line throughout
  2. B
    Flat segment at 0°C, slope segments elsewhere
    Correct
  3. C
    Exponential rise
  4. D
    Flat at −10°C then linear

Correct answer

Flat segment at 0°C, slope segments elsewhere

Explanation

Ice heats to 0°C (slope), melts at 0°C (flat), water heats (slope), boils at 100°C (flat), steam heats (slope).
