Some Thermal Dynamic help.

[derfrok]

Ok, I don't quite understand the concept of thermal dynamics. So, I need some help here.

When ice melts it takes 333,465 Joules of energy to convert one 1KG of solid ice into liquid water at 0 degrees celsius. Suppose that you have a one cubic foot block of ice.

I need to find the MASS. Can someone please point me in the right direction? :biggrin:

Here's what i got so far:

333,465j=M*2000j/kg-celsius(0-20)?????

I presume the question is to find out how much energy is needed to melt that much ice at 0 degrees? If so, look up the density of ice in order to find the mass of this block. (I think it's something like 917 kg/m^3.)
