From: | To: |
The ice to water heating calculation determines the total energy required to melt ice and then heat the resulting water to a desired temperature. It combines the latent heat of fusion and sensible heat components.
The calculator uses the energy calculation formula:
Where:
Explanation: The first term calculates energy for phase change (melting), the second term calculates energy for temperature change.
Details: Accurate energy calculation is crucial for thermal system design, climate studies, and understanding phase change processes in various applications.
Tips: Enter mass in kg, latent heat in J/kg (default 334,000 J/kg for water), specific heat in J/kg·K (default 4,186 J/kg·K for water), and temperature change in Kelvin. All values must be positive.
Q1: Why is latent heat needed in the calculation?
A: Latent heat accounts for the energy required to change the phase from solid to liquid without temperature change.
Q2: What are typical values for water?
A: For water, latent heat of fusion is 334,000 J/kg and specific heat capacity is about 4,186 J/kg·K.
Q3: Does this account for heating the ice before melting?
A: No, this calculator assumes ice is already at 0°C. For ice below 0°C, an additional term would be needed.
Q4: Can this be used for other substances?
A: Yes, with appropriate values for latent heat and specific heat of the substance in question.
Q5: How does pressure affect the calculation?
A: At standard pressures, these values are accurate. For extreme pressures, different values may be needed.
