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:

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
