Respuesta :
A 7.25 kg lead brick with a starting temperature of 18.0 °C needs a minimum of 4.56 x 105 J to melt fully. 328 °C is the melting temperature of lead. Lead has a latent heat of fusion of 23,200 J/kg and a specific heat capacity of 128 J/(kg C).
Here, the formula is: Q = mc (T2 -T1) = mL
what is Specific heat capacity ?
"The amount of heat required to change the temperature of a unit mass of the substance by one degree" is the definition of specific heat capacity for any substance.
Specific heat capacity is a sort of thermal inertia since it shows how resistant a substance is to changes in temperature. In connection with this formula, specific heat capacity information.
What precisely is latent heat of fusion?
The amount of energy that must be added to a solid substance (usually in the form of heat) to cause a change in its physical state and transform it into a liquid is known as the latent heat of fusion, also known as the enthalpy of fusion (when the pressure of the environment is kept constant). For instance, the latent heat of fusion of one kilogram of water is 333.55 kilojoules, which is the amount of heat energy required to transform one kilogram of ice while maintaining a temperature of zero degrees Celsius in the surrounding space.
