# For heating 200 g of transformer oil from 24 to 40 degrees. celsius required the amount

For heating 200 g of transformer oil from 24 to 40 degrees. celsius required the amount of heat 5.4 kJ. What is the specific heat of transformer oil?

Initial data: m (mass of transformer oil) = 200 g (0.2 kg); tн (initial temperature of transformer oil) = 24 ºС; tк (final temperature) = 40 ºС; Q (required amount of heat) = 5.4 kJ (5400 J).

We express the specific heat capacity of the transformer oil from the formula: Q = C * m * (tк – tн); C = Q / (m * (tк – tн)).

Calculation: C = 5400 / (0.2 * (40 – 24)) = 1687.5 J / (kg * ºС).

Answer: According to the calculation, transformer oil has a specific heat capacity of 1687.5 J / (kg * ºС).
