Explanation Given: Temperature at the center of the sun, Tsun = 2 x 107 K Formula used: (i) εavg = (3/2)kT (ii) vrms = √ (3kT/m) Calculation: a) The relation between average kinetic energy and temperature states that, avg = (3/2)kT Therefore, average kinetic energy for a proton at the center of the sun, εavg sun = (3/2)kTsun = (3/2)(1 .38 x 10-23 J/K)(2 x 107 K) = 4 .14 x 10-16 J b) The relation between rms speed and temperature states that, vrms = √ (3kT/m), where m is the mass of a molecule m for a proton, mp = 1

Kinetic Theory of Gas

The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all dire…

P-V Diagram

A P-V diagram is a very important tool of the branch of physics known as thermodynamics, which is used to analyze the working and hence the efficiency of thermodynamic engines. As the name suggests, it is used to measure the changes in pressure (P) and v…
