Problem
The latent heat of fusion (solid become liquid) for ice is 79.8 cal/gram. How much ice can we melt with 1000 calories of heat?

Problem
Which would require more heat, melting 500 g of 0 C ice or turning 500 g of 100 C water into steam?
Problem
A 500 g sample of an unknown material requires 750 calories of heat to raise its temperature by 50 C. Use Equation (1) and Table 6.1 to identify the material.

  • math -

    Heat=Lf*mass
    solve for mass.

    In the second, compare the heats of fusion/vaporization. One is about six times as great as the other.

    You will have to do it yourself. Find the heat capacity, and look in the table.
