Determine the quantity of ice required to absorb exactly 50 kJ of energy when the ice warms from -50.0°C to -10.0°C (specific heat of ice = 2.06 J g^-1 °C^-1).

Question

Quizplus · Accepted Answer

To find the mass of ice, use the formula q = mcΔT, where q is the energy absorbed (50,000 J), c is the specific heat capacity (2.06 J/g°C), and ΔT is the temperature change (40°C). Solving for m gives m = q / (cΔT) = 50,000 / (2.06 * 40) = 607 g.
