Which would keep you warmer through the cold night-a 10-kg iron brick or a 10-kg jug of hot water at the same temperature?

The 10 kg of water. This is because the Specific Heat Capacity for water is 9x larger than Iron. The SHC for water is that it takes 1 calorie of water to raise 1 gram by 1 degrees celsius (1C/1gram X 1 degrees celsius) for Iron it takes 0.11 Calories to raise 1 gram by 1 degrees celsius. Therefore meaning since Water has a higher Specific Heat Capacity, it'll take longer to cool down. Just as it requires a large amount of heat to raise the temperature by 1 degrees Celsius, it requires a large amount of heat to drop the temperature by 1 degrres Celsius.
