How do i find how long it takes to melt an ice cube? can i use this heat transfer equation below i took the weight of the ice cube and was gonna melt the ice cube in a controlled environment (microwave) and find the rate the heat is transferred from the wattage of the microwave. and i think i can find the time it takes for the ice cube to melt from that heat transfer equation Q = mC(deltaT) but im not too sure. please help me.

Even if you knew these you couldn't know .... do an experiment to find the answer ...that's what science is about experiment topsquark likes this.
