Calculate the amount of heat required to heat 1 m3 of sand to 60 degrees C.

Task data: m (mass of taken sand) = 1 m3; Δt (required change in sand temperature) = 60 ºС.

Reference values: ρ (bulk density of sand) = 1500 kg / m3; Cn (specific heat capacity of sand) = 0.835 kJ / (kg * K) = 835 J / (kg * K).

The required amount of heat for heating 1 m3 of sand is determined by the formula: Q = Cp * m * Δt = Cp * ρ * V * Δt.

Calculation: Q = 835 * 1500 * 1 * 60 = 75.15 * 10 ^ 6 J (75.15 MJ).

Answer: To heat 1 m3 of sand, 75.15 MJ of heat is required.
