How do you find the specific heat capacity of methanol?
At ambient pressure and temperature the isobaric specific heat, CP, of liquid methanol is 2.53 [kJ/kg K] or 0.605 [Btu/lb °F] = [cal/g K], while the isochoric specific heat, CV, is 2.12 [kJ/kg K] or 0.506 [Btu/lb °F] = [cal/g K].
How would you find the specific heat of a solid?
The heat capacity C of an object is defined as C = ∆Q/∆T, where ∆Q is the amount of heat required to change the temperature of the object by ∆T. The specific heat c of a substance is the heat capacity per unit mass. The specific heat is measured in J/kg℃ or cal/g℃ or kcal/kg℃.
What is the specific heat of solid ethanol?
The specific heats of solid and liquid ethanol are 0.97 J/g•K and 2.3 J/g•K, respectively.
What is Einstein theory of specific heat?
A theory of the specific heat of solids proposed by Albert Einstein in 1906. In this theory, Einstein attributed the specific heat of solids to the vibrations of the solid and made the simplifying assumption that all the vibrations have the same frequency.
What is specific heat of a solid?
The amount of heat required to increase the temperature of a unit mass of a solid by a unit amount. The term “specific heat” is short for “specific heat capacity” of a solid. It is determined by the vibrations of the solid’s atoms or excitations of its electrons, and also by a variety of phase transitions.
What is the specific heat of alcohol?
Specific heats and molar heat capacities for various substances at 20 C
