Question 157

Two identical electric heaters are used to heat two metal blocks, Block A and Block B, of equal mass. Both heaters are turned on for three minutes. It is observed that the temperature rise of Block A is much less than the temperature rise of Block B.

Why is this?

A

Block A has a higher melting point than Block B.

B

Block A has a lower melting point than Block B.

C

Block A has a larger thermal capacity than Block B.

D

Block A has a smaller thermal capacity than Block B.
