when specific heat capacity of gas be positive
Answers
Explanation:
Heat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to a given mass of a material to produce a unit change in its temperature.[1] The SI unit of heat capacity is joule per kelvin (J/K).
Heat capacity is an extensive property. The corresponding intensive property is the specific heat capacity. Dividing the heat capacity by the amount of substance in moles yields its molar heat capacity. The volumetric heat capacity measures the heat capacity per volume. Heat capacity is often referred to as thermal mass in architecture and civil engineering to refer to the heat capacity of a building .
hope it helps you!!
mark as brain list!!
Answer:
In the chapter on temperature and heat, we defined the specific heat capacity with the equation Q=mcΔT, or c=(1/m)Q/ΔT. However, the properties of an ideal gas depend directly on the number of moles in a sample, so here we define specific heat capacity in terms of the number of moles, not the mass.
