Heat required to Melt Joint Solution

STEP 0: Pre-Calculation Summary

Formula Used

Heat Required = Mass in Flight Path*((Specific Heat Capacity at Constant Pressure*Rise in Temperature)+Latent Heat of Fusion)
H_req = M_fp*((C_p*ΔT_rise)+L_f)
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 in Flight Path - (Measured in Kilogram) - Mass in Flight Path 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 one 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 in Flight Path: 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

H_req = M_fp*((C_p*ΔT_rise)+L_f) --> 0.5*((1005*16)+15)

Evaluating ... ...

H_req = 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

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.
