1.00 kg of solid Hg at its melting point of -39∘C is placed in a 0.620-kg aluminum calorimeter with 0.400 kg of water at 12.80 ∘C; the resulting equilibrium temperature is 5.06 ∘C. The specific heat of aluminium is 900 J/kg⋅C∘, specific heat of water is 4186 J/kg⋅C∘, specific heat of mercury is 138 J/kg⋅C∘. Determine the latent heat of fusion of mercury using the given data?

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy. work depends on the square of the change in potential energy. work is equal to the negative of the change in kinetic energy. work is equal to the square of the change in kinetic energy
