Explanation As the amount of heat H required to melt ice is directly proportional to the mass m of ice that is needed, the equation for this direct proportion is given by, H = k m ( ∵ H denotes the amount of heat and m denotes the mass of ice and k is the constant of proportionality . ) ... ( 1 ) It is given that it takes 2.93 × 10 5 J of heat to melt 875 g of ice. Therefore, the value of k is obtained by substituting the known values of amount of heat and mass of ice in the equation (1) as follows. 2.93 × 10 5 J = k × 875 g k = 2
