Two blocks
Two large blocks of the same mass and approximately the same volume are
originally both at room temperature. They are placed on a hot plate set
at 90C. One is made of silver and the other is made of copper. A group of
students observe that the copper block takes nearly twice as long to
reach a temperature of 90!C as the silver block. Given that copper and
silver conduct heat at approximately the same rate, the best explanation
the students could give for this observation would be that
A. The copper block needs to absorb more heat than the silver block
for its temperature to increase by the same amount.
B. Silver has a higher specific heat capacity than copper.
C. Copper has a higher specific heat capacity than silver.
D. Copper has a higher thermal conductivity than silver.
E. Both A and C are true.
F. Both A and B are true.
