These tasks: Q (released thermal energy from the combustion of the consumed mass of peat) = 700 MJ (700 * 10 ^ 6 J).

Reference values: qt (specific heat of combustion of peat) = 1.4 * 10 ^ 7 J / kg.

To determine the consumed mass of burnt peat, we will use the formula: m = Q / qt.

Calculation: m = 700 * 10 ^ 6 / (1.4 * 10 ^ 7) = 50 kg.

Answer: 50 kilograms of peat burned out.
