SUMMARY
The heat required to evaporate 1 kg of water at temperatures below 100 degrees Celsius can be calculated using the latent heat of vaporization specific to the desired temperature. The heat transfer equation Q = mcΔt is typically used for raising temperature, but for evaporation at constant temperatures, the latent heat values must be referenced. For example, at 50 degrees Celsius, the latent heat of vaporization differs from that at 100 degrees Celsius, necessitating the use of resources like the Engineering Toolbox for accurate values.
