Problem data: m (mass of heated glycerin) = 2 kg; Δt (temperature change) = 1 ºС; Q (heat consumption for heating glycerin) = 4800 J.

To determine the specific heat of glycerin, we use the formula: Q = Cg * m * Δt, whence Cr = Q / (m * Δt).

Let’s calculate: Q = 4800 / (2 * 1) = 2400 J / (kg * K).

Answer: The specific heat capacity of glycerin, according to the calculation, is equal to 2400 J / (kg * K).
