Question 4

Water takes a shorter time to boil on the mountain top compared to in the valley although the same electric kettle is used. This is because of

1. the air on the mountain top is less damp
2. the mountain top is cooler than the valley
3. the atmospheric pressure is higher in the valley
4. the rate of heat loss is faster on the mountain top
5. None of the above.
