You have a block of ice at 32 degrees F, and a block of copper at some other temperature. The blocks have equal mass. Exactly the same amount of heat is added to each block. This causes the ice to melt completely, but not to warm up past 32 degrees F. The copper stays well below its melting point.

How much does the copper expand?

(Express your answer as a percentage, e.g. "the length of the copper increases by 1%.")

Helpful values:

  • the specific heat of copper is 386 J / (kg*K)
  • the coefficient of thermal expansion of copper is 1.65 x 10-5 per Kelvin
  • the latent heat of water is 334 kJ/kg
