SUMMARY
The discussion centers on calculating the heat required to convert 1.0 kg of water at 85°C to steam at 118°C. The relevant formula used is Q = mcΔT, where m is mass, c is specific heat capacity, and ΔT is the change in temperature. The specific heat capacity of water is 4186 J/kg°C. The total heat required includes both the heat needed to raise the temperature of the water to 100°C and the heat required for the phase change from water to steam, followed by heating the steam to 118°C.
PREREQUISITES
- Understanding of thermodynamics principles, specifically heat transfer.
- Familiarity with the specific heat capacity of water (4186 J/kg°C).
- Knowledge of phase changes and latent heat of vaporization (2.26 x 10³ kJ/kg).
- Ability to apply the formula Q = mcΔT in practical scenarios.
NEXT STEPS
- Calculate the heat required to raise the temperature of water from 85°C to 100°C using Q = mcΔT.
- Determine the latent heat required for the phase change from water to steam at 100°C.
- Calculate the heat needed to raise the temperature of steam from 100°C to 118°C.
- Combine all calculated heat values to find the total heat required for the conversion.
