Question

Suppose you heat an oven to 400°F (about 200°C) and boil a pot of water. Which of the following explains why you would be burned by sticking your hand briefly in the pot but not by sticking your hand briefly in the oven? A.The water has a higher temperature than the oven. B.The water can transfer heat to your arm more quickly than the air. C.The oven has a higher temperature than the water. D.The molecules in the water are moving faster than the molecules in the oven.

Answer 1

B

Step-by-step explanation:

Temperature of air in the oven (about 200°C) is higher than the water in the pot (100°C) → Option A is wrong

When the temperature is higher, the particles (molecules) also move faster → Option D is wrong

The reason is water's molecule density (liquid) is much higher than air's molecule density (gas) → water can transfer energy much faster than air → Option B is correct

Option C is correct too but doesn't related to the question
