Heat required to Melt Joint Solution

STEP 0: Pre-Calculation Summary
Formula Used
Heat Required = Mass*((Specific Heat Capacity at Constant Pressure*Rise in Temperature)+Latent Heat of Fusion)
Hreq = Massflight path*((Cp*ΔTrise)+Lfusion)
This formula uses 5 Variables
Variables Used
Heat Required - (Measured in Joule) - Heat Required is the amount of energy that is required for a particular process.
Mass - (Measured in Kilogram) - Mass is the quantity of matter in a body regardless of its volume or of any forces acting on it.
Specific Heat Capacity at Constant Pressure - (Measured in Joule per Kilogram per K) - Specific Heat Capacity at Constant Pressure means the amount of heat that is required to raise the temperature of a unit mass of gas by 1 degree at constant pressure.
Rise in Temperature - (Measured in Kelvin) - Rise in Temperature is the increment in temperature of a unit mass when the heat is applied.
Latent Heat of Fusion - (Measured in Joule per Kilogram) - The Latent Heat of Fusion is the amount of heat required to convert one unit amount of substance from the solid phase to the liquid phase — leaving the temperature of the system unaltered.
STEP 1: Convert Input(s) to Base Unit
Mass: 0.5 Kilogram --> 0.5 Kilogram No Conversion Required
Specific Heat Capacity at Constant Pressure: 1.005 Kilojoule per Kilogram per K --> 1005 Joule per Kilogram per K (Check conversion here)
Rise in Temperature: 16 Kelvin --> 16 Kelvin No Conversion Required
Latent Heat of Fusion: 15 Joule per Kilogram --> 15 Joule per Kilogram No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Hreq = Massflight path*((Cp*ΔTrise)+Lfusion) --> 0.5*((1005*16)+15)
Evaluating ... ...
Hreq = 8047.5
STEP 3: Convert Result to Output's Unit
8047.5 Joule -->8.0475 Kilojoule (Check conversion here)
FINAL ANSWER
8.0475 Kilojoule <-- Heat Required
(Calculation completed in 00.004 seconds)

Hreq = Massflight path*((Cp*ΔTrise)+Lfusion)

What is latent heat of fusion?

During the process of melting, the solid and liquid phases of a pure substance are in equilibrium with each other. The amount of heat required to convert one unit amount of substance from the solid phase to the liquid phase — leaving the temperature of the system unaltered — is known as the latent heat of fusion. It is also equal to the enthalpy difference between the solid and liquid phases.
