A student puts equal volumes of water into two identical metal cups. One cup is wrapped with a thick cloth, the other is left bare. Both are left in a cold room. Which statement predicts what happens after 20 minutes?
- Water in the wrapped cup is warmer because the cloth reduces heat loss.
- Water in the bare cup is warmer because it can lose heat faster.
- Both cups have the same temperature because they started the same.
- Water in the wrapped cup is cooler because the cloth absorbs its heat.
