You have a block of ice with dimensions 30cm30cm30cm. The properties of ice are available in the Level 3 database of the Granta software, but are included here for your convenience: - =910kg/m3 - =2.1WmK/ - cP=2100JkgK/ - Latent Heat of Fusion, Hf=340kJkg/ 1. How much energy is required to melt the entire block of ice, initially at a temperature TO=10 C ? a. First, describe in words the procedure you would follow to solve the problem. b. Perform the calculation. 2. The same block of ice is placed in a tight-fitting box made of low-density, rigid polymer foam (Granta, Level 1 database). Assuming the initial temperature of the ice, TO=0C, and an exterior temperature of 30C, how long do you predict it will take to melt the entire block of ice if the wall thickness of the box is 2.0cm. a. Again, first describe in words the steps you would follow to solve the problem. Include any assumptions you would make, and whether the assumption(s) would lead to an over-, or under-estimate of the actual time taken to melt the ice. b. Perform the calculation
