I'm trying to find possible errors in this lab experiment that I did, and one question I am thinking about is "Does ice melt linearly?" I assumed that it does so in my calculations, but now I'm not so sure. I measured the mass of melted ice (water) over a period of time and assumed that it melted at a constant rate. Since the density of ice is intrinsic (ρ = m/V) and would be constant, it made sense that the volume would change at the same rate as the mass. So that led me to believe that volume decreased at a constant rate too. Were these valid assumptions to make? Does ice melt linearly or by some other function of time?
