Question

What is true about a block of ice at -10 degrees celsius as you continue to apply heat...

more than one can be correct.

a, its temperature will rise continuously until it completely melts
b, its temperature will rise until reaching 0 degrees
c, its temperature will not rise above -10 degrees until it melts
d, its temperature will remain at 0 degrees until all the ice melts

Answer 1

A. Its temperature will rise continuously until it completely melts

I don't believe that any of the other answers are correct because the ice cannot stay at a certain temperature if it is melting.
