1. What two forces are balanced in gravitational equilibrium? Describe how gravitational equilibrium makes the Sun hot and dense in its core. The two forces that are balanced in gravitational equilibrium are outward pressure and gravity. The outward pressure tries to make an object, like the earth, expand…

Introduction

In the Sun’s core, the weight of the layers above is very large so that the pressure needed to balance it is also large. Pressure is the product of temperature and density, so high pressure means high densities and high temperatures in the core. The energy released by nuclear fusion heats the gas and maintains the pressure that is needed to cause the nuclear fusion. 2. What is the difference between nuclear fission and nuclear fusion? Which one is used in nuclear power plants? Which one is used by the Sun? Nuclear fusion is the combination of two or more nuclei to form a new element with higher atomic number. The amount of energy released in the fusion reaction is equal to E = mc 2. Nuclear fission is splitting of massive nucleus into photos in the form of free neutrons, other subatomic particles, and gamma rays. The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one. Nuclear fission is the process used in the production of nuclear power. Fission involves splitting the nucleus of a heavy atom, such as uranium. This yields two or more lighter nuclei and a large amount of energy. ...

It all starts with a cloud of gas. Due to gravity the cloud will start to shrink. This collapse is usually triggered by a shockwave from a nearby supernova or expanding planetary nebulae.  As the cloud contracts the rotation will become faster and it will break up into individual clumps. If these masses are big enough the density and temperature in the core will become high enough so…
