The specific heat of tungsten
The specific heat of tungsten.
The specific heat of tungsten:
Heat capacity is the quantity of heat absorbed (emitted) whole body in the process of heating (cooling) by 1 Kelvin.
Specific heat is a physical quantity, numerically equal to the quantity of heat which must be transferred to a body with mass of 1 kg in order that its temperature has changed by 1 Kelvin.
Specific heat capacity is denoted by c and is measured in j/(kg·K).
C = Q / (m·ΔT),
where Q is the quantity of heat received by the substance when heated (or precipitated during cooling),
m is the mass of the heated (cooled) material,
ΔT – difference between the final and initial temperatures of the substance.
The specific heat of tungsten (C) is 0,134 kJ/(kg·K).
The specific heat of tungsten is given at a temperature of 0 °C.
You must keep in mind that the specific heat capacity of a substance is affected by the temperature and other thermodynamic parameters (volume, pressure, etc.) and how did the changes of these thermodynamic parameters (for example, at constant pressure or at constant volume).
The exact value of the specific heat capacity of metals depending on the thermodynamic conditions (temperature, volume, pressure, etc.) need to look in directories.
