How do you calculate CP of a gas? cp = cv + R The specific heat constants for constant pressure and constant volume processes are related to the gas constant for a given gas. How do you calculate the gamma of CO2? Calculate the values of γ=Cp/Cv for a gaseous mixture consisting of v1=2.0 moles […]

What is the dimensional formula for gas constant? Or, G = [M1 L-1 T-2] × [L3] × [K1]-1 = [M1 L2 T-2 K-1]. Therefore, the gas constant is dimensionally represented as [M1 L2 T-2 K-1]. What is the dimensional formula of Boltzmann constant? Or, k = [M1 L2 T-2] × [M0 L0 T0 K1]-1 = […]

How can you tell the difference between feldspar and quartz? Explain Since both quartz and feldspar are considered hard and would scratch glass after a hardness test, you can tell the difference by the mineral’s cleavage. Quartz has poor or absent cleavage, while feldspar has excellent or good cleavage. Which is harder quartz or feldspar? […]
