An electric heater is used to heat two identical beakers, one containing liquid A and the other containing an equal mass of liquid B. Both are heated for 3 minutes.
The temperature of both liquids increases steadily. However, the temperature rise of liquid A is much less than the temperature rise of liquid B.
Why is this?
Liquid A has a higher boiling point than liquid B.
Liquid A has a lower boiling point than liquid B.
Liquid A has a larger thermal capacity than liquid B.
Liquid A has a smaller thermal capacity than liquid B.
