How many grams of water at 55 °c is needed to melt 2000 g of ice at 0 °c?

2903 g

Explanation:

Given:

The final equilibrium temperature of this system should be 0 degrees Celsius, as we only melt the ice, so all of the heat lost by the water at 55 degrees Celsius will be used to melt ice. Heat given off by the water is described by:

Heat gained by the ice:

Heat gained should be equal to the heat lost:

Solve for the mass of water:

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

um i think it might be a car?
