| June 19, 2021 | education
These tasks: m (mass of heated water) = 5 g (0.005 kg); Δt (required change in water temperature) = 10 ºС.
Reference data: C (specific heat capacity of water) = 4200 J / (kg * K).
The required amount of heat to change the temperature of 5 g of water is calculated by the formula: Q = C * m * Δt.
Calculation: Q = 4200 * 0.005 * 10 = 210 J.
Answer: You need 210 Joules of heat.
