Question

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. copper 

4. water

Answer 1

Correct option (4) water
