(c) The Orion nebula is one of the brightest diffuse nebulae in the sky (look for it in the winter, just below the three bright stars in Orion's belt). is a very complicated mess of gas, dust, young star systems, and brown dwarfs, but let's estimate its temperature if we assume it is a uniform ideal gas. ssume it is a sphere of radius r = 4.1 × 1015 m (around 6 light years) with a total mass 4000 times the mass of the Sun.

Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.

(c) The Orion nebula is one of the brightest diffuse nebulae in the sky (look for it in the winter, just below the three bright stars in Orion's belt).
It is a very complicated mess of gas, dust, young star systems, and brown dwarfs, but let's estimate its temperature if we assume it is a uniform ideal gas.
Assume it is a sphere of radius r = 4.1 × 1015m (around 6 light years) with a total mass 4000 times the mass of the Sun. If the gas is all diatomic hydrogen and
the pressure in the nebula is P,= 6.3 × 10-9 Pa, what is the average temperature (in K) of the nebula? Assume the mass of the sun is M, = 1.989 × 1030 kg and
the mass of a hydrogen atom is my= 1.67 × 10-27 kg.
