Consider the following specific heats: copper, 0.384 J/g· °C; lead, 0.159 J/g· °C; water, 4.18 J/g· °C; glass, 0.502 J/g· °C. Which substance, once warmed, would be more likely to maintain its heat and keep you warm through a long football game on a cold night? 1. glass 2. lead 3. water 4. copper

3. water

Explanation:

Specific Heat: Specific heat of a substance is the energy required to increase temperature of 1 gram of substance by 1°C

Here water has the highest specific heat in the list,so it emit largest amount of heat with lose of small amount of temperature.

So,water can warmed body until its temperature becomes below the body temperature.
