WebThe dimensions of the universal gas constant R are energy per degree per mole. In the metre-kilogram-second system, the value of R is 8.31446261815324 joules per kelvin (K) per mole. The universal gas constant is defined as Avogadro’s number NA times the Boltzmann constant k. Britannica Quiz Science: Fact or Fiction? WebThe volume of a cone of radius r and height h is given by V = 1/3 pi r^2 h. If the radius and the height both increase at a constant rate of 1/2 cm per second, at what rate in cubic cm per sec, is the volume increasing when the height is 9 cm and the radius is 6 cm. I tried letting r = 2/3 h and doing a substitution.

As of 2006, the most precise measurement of R had been obtained by measuring the speed of sound ca(P, T) in argon at the temperature T of the triple point of water at different pressures P, and extrapolating to the zero-pressure limit ca(0, T). The value of R is then obtained from the relation where: • γ0 is the heat capacity ratio (5/3 for monatomic gases such as argon);
