The hot glowing surfaces of stars emit energy in the form of electromagnetic radiation. It is a good approximation to assume that the Emissivity e is equal to 1 for these surfaces. Find the radius RRigel of the star Rigel, the bright blue star in the constellation Orion that radiates energy at a rate of 2.7 x 1031 W and has a surface temperature of 11,000 K. Assume that the star is spherical Use σ = 5.67 × 10-8 w/m2-K4...

Problem 2: In a given lab session a group of students performed a sequence of thermodynamic processes to a given gas. Before performing the process the studenta recorded the initial pressure of the gas as being 101.5 kPa and its temperature equal to 2000 The sequence can be described as firstly isochoric heating in which the gas temperature is increased by 25% of its initial temperature, followed by an isothermal compression in which the volume of the gas is reduced...
