Initial data: t1 (initial temperature of glycerin) = 10 ºС; t2 (final temperature of glycerin) = 15 ºС; Q (the amount of heat that glycerin absorbed when heated) = 12 kJ = 12 * 10 ^ 3 J.
Constants: C (specific heat capacity of glycerin) = 2350 J / (kg * K).
The mass of glycerin can be expressed from the following formula:
Q = C * m * (t2 – t1) and m = Q / (C * (t2 – t1)).
Let’s perform the calculation:
m = 12 * 10 ^ 3 / (2350 * (15 – 10)) = 1.02 kg.
Answer: The mass of glycerin is 1.02 kg.
