Heat energy gained formula
WebSolved Examples for Heat Loss Formula. Q.1: Determine the total heat loss from the building whose area is 60 sq. m, the coefficient of heat transfer is 0.7 and the temperature difference is 25 ∘ C. Solution: Given, U = 0.7. A = 60. Substitute these values in the given formula, q = 0.7 x 60 x 25. Therefore, q = 1050 watts. WebGiven heat q = 134 J. Given mass m = 15.0 g. Change in temperature: Δ T = 62.7 – 24.0 = 38.7. To find specific heat put the values in above specific heat equation: q m × Δ T = 134 15 × 38.7 = 0.231. However, a specific heat calculator can assist you in finding the values without any hustle of manual calculations.
