Melting Ice Cubes aka. Thermodynamics and Heat Transfer HIGH ASPIRATIONS Created by: Dave Johnson Kathy Holliday-Darr Miracle Thaw Is it really a miracle? Let’s check it out… Melting Ice Cubes: “Icebreaker” J First experiment objective:
First experiment objective:
Determine how fast each different test material melts an ice cube AND how the melting of the ice cube effects the test material’s temperature.
Some important material properties:
(Tfinal - Tinitial)
= (0.5 kg)(434 Joules/kg-oC)(22-7 oC)
= 3255 Joules
Better yet, we can solve for the final temperature of the steel to melt the ice:
How do you make the ice cubes melt faster ?
What do the terms in Fourier’s Law show us ?
Which variables can you control ?
The rate of heat flow is:
