Saturated and Unsaturated Vapour Pressure

Saturated and Unsaturated Vapour Pressure What is a saturated solution? If in a water sugar solution, the amount of dissolved sugar is equal to the maximum amount that a given amount of water can dissolve at a certain temperature, then that solution is called a saturated solution. What is an unsaturated solution? If in a water sugar solution, the amount of dissolved sugar is less than that amount that a given amount of water can dissolve at a certain temperature, then that solution is called a saturated solution. What is saturated vapour? At a certain temperature in an enclosed space, if the amount of vapour present is equal to the maximum vapour capacity of that space, then that vapour is called saturated vapour. What is unsaturated vapour? At a certain temperature in an enclosed space, if the amount of vapour present is less than the maximum vapour capacity of that space, then that vapour is called unsaturated vapour. What is vapour pressure? Vapour enclosed in a container behaves

When a shot is fired from a gun, the gun pushes backward why?

When a shot is fired from a gun, the gun pushes backward why?

When a shot is fired from a gun the gun is pushed backward at the time. In this case, the action and reaction force off the bullet and the gun exist at the same time. 

According to Newton's second law of motion, the bullet and the gun equal and opposite momentum. As a result, the bullet moves forward with a particular momentum and the gun moves backward with a momentum of the same magnitude but opposite in direction. Due to this, the person will feel a backward thrust. The backward velocity of the gun will be smaller in compression to that of the bullet is the mass of the gun is large.
