How much heat is required to heat 5 liters of water from 10 degrees to 15 degrees.

In order to calculate how much heat the water must receive in order to heat up from a temperature of 10 degrees to a temperature of 15 degrees, we will use the formula: Q = m • c • Δt. The mass of water can be found through the formula: m = ρV, where the density of water is ρ = 1000 kg / cubic meter, and the volume is V = 5 l = 5 cubic dm = 0.005 cubic meters. We get the mass m = 5 kg (1 kg of water takes up a volume of 1 liter). Specific heat capacity of water c = 4200 J / (kg • deg), temperature change Δt = 15 – 10; Δt = 5 degrees. We get Q = 5 kg • 4200 J / (kg • deg) • 5 deg = 105000 J.
Answer: required for heating 105,000 J.
