What is Heat Capacity?
- A physical feature of matter known as heat capacity or thermal capacity is the quantity of heat that must be applied to an object in order to cause a unit change in temperature.
- Heat capacity is measured in joules per kelvin (J/K), the SI unit.
- A broad property is heat capacity. The specific heat capacity, which can be calculated by dividing an object's heat capacity by its mass, is the comparable intense attribute.
- The molar heat capacity is obtained by dividing the heat capacity by the molecular weight of the substance.
- The heat capacity per volume is gauged by the volumetric heat capacity. The term "thermal mass" is frequently used in architecture and civil engineering to describe a building's ability to hold heat.
<u>solution:</u>
According to the data given in the question, we have
The heat of combustion for the acetone = -11.63 kJ/g (Here the negative sign depicts the release of heat and only magnitude is considered for the heat capacity)
The given mass of acetone = 2.53g
The change in temperature due to the combustion = Δt = 3.03 °C
Now, using formula for the heat capacity is given as:
Heat capacity (C) =
or , C =
or, C = 9.71 kJ/ °C
