What is the heat capacity of a mixture?
The mass of each individual component is equivalent to the total mass of the mixture, which can theoretically be broken down into separate parts. Heat capacity is a measurable physical quantity equal to the ratio of the heat added to (or removed from) an object to the resulting temperature change.

Why specific heat capacity of water is so high?
Water’s high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.
What is the specific heat value 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]. However, the specific heat – CP and CV – will vary with temperature.
How do you find heat capacity from specific heat capacity?
The specific heat capacity is the heat or energy required to change one unit mass of a substance of a constant volume by 1 °C. The formula is Cv = Q / (ΔT ⨉ m) .

How do you find the specific heat capacity of water experiment?
1. Given that the specific heat capacity of the calorimeter ccal is known, the specific heat capacity of water cw can be calculated from the following equation: Electrical energy supplied = energy gained by water + energy gained by calorimeter Q = mwcw + mcalccal .
