Answer: 1. Water would be more likely to maintain its heat through a cold night.

Since water has a greater heat capacity than copper, lead and glass it is more likely to heat up and cool slowly

Explanation:

heat capacity is the energy requires to raise one gram of a substance by one degree Celsius (the specific heat capacity). Heat capacity relates to a substance's ability to retain heat and its rate to heat up and cool. A substance with a low heat capacity will cool quickly while a substance with a high heat capacity such as water will cool slowly.
