A problem with a phase change
Here's a problem involving phase change:
How much heat is required to melt a 13.9 g ice cube at 0oC? (The heat of fusion (ΔHfus) of ice is 79.7 cal/g)
This problem involves a change of state, so the formula needed is
So, what do we know?
We're missing the value for heat, so we don't need to rearrange the formula. We can just substitute in our numbers and do the math.
\cdot(79.7~cal/g)=1108~cal "q = m \cdot \Delta H_{fus} = (13.9~g)\cdot(79.7~cal/g)=1108~cal")
Let's try one more.
