23. Why does water heat up and cool it has a higher specific heat
down slower than land?
it has a higher specific heat

24. the lead because it has a lower specific heat
If you heated equal masses of
basalt and lead, which one would
record a faster increase in
temperature? Explain how you know.
the lead
because it has a lower specific heat
