Answer to Question #150492 in Molecular Physics | Thermodynamics for Banda

Question

The temperature of 4.5 kg of water is raised from 15 °C to 100 °C at constant atmospheric pressure. Determine the heat transfer required

Answer 1

Solution to question #150492

Heat transferred formula is Q = m × c × Δ T where Q is heat transferred, m is mass, c is specific heat and Δ T is the change in temperature. Specific heat of water is 4.2j/g°C.

So, Q=4500g*4.2j/g°C*85°C

Q=1,606,500 joules or 1,606.5Kilojoules

Heat transfer required(Q) is 1,606,500 joules
