Question

Can you use the following information to explain the launch of a rocket?: Hot gasses that escape from a rocket have a very small mass but a high velocity. As fuel is used up, the mass of teh rocke decreases.

Answer 1

True, the rapid burning of fuel cause a HIGH VELOCITY of gases to leave the nozzle, there they expand geometrically to cause a huge difference is pressue at the nozzles end to that of the surround atmosphere . This difference is pressure causes the rocket to accelerate rapidly . The loss of fuel during consumption allows the rocket to maintain its high acceleration that was achieved by the loss of mass (or weight) couple that with a increasing distance from the earth (where a=32 fps squared originally and fast decreasing) and you have a speed up of the rocket or its accelerated, to the point at which the rocket is turned to an eliptical orbit around the earth. The eliptical orbit then cause the rockes acceleration to diminish and a constant velocity is then maintained around the earth as the forces then become balanced all developed thur careful calculations of the rockes loss in original mass, and a calculated loss in acceleration as it makes a turn to an eliptical orbit pattern.

Answer 2

"As fuel is used up, the mass of the rocket decreases. "This is true and relevant to explaining the way the rocket accelerates over the time that the fuel is burning.
"Hot gasses that escape from a rocket have a very small mass but a high velocity". This is not quite true, the fuel, which turns into the hot gas, is often a large fraction of the total rocket mass (so the mass of gas is not small). The velocity is generally high though.
Between them these do not explain the launch of a rocket. You need to add something to link the emission of the gasses to the force that propels the rocket forwards.

Answer 3

The answer lies in combustion thermodynamics. Any thrust producing engine is a heat engine and therefore follows the Carnot cycle. A rocket is no exception.

The performance of rocket engines can be calculated from motor geometry and measurements of thermodynamic quantities such as temperature and pressure. The combustion of the fuel-oxidizer mixture, a chemical reaction, increases the pressure and temperature of the gaseous products of the reaction. The gas is accelerated by the converging part of the nozzle until it reaches sonic speed at the throat. At supersonic speeds, the divergent section further accelerates the gas as it expands to atmospheric pressure and temperature. As it expands, its heat content is converted to thrust (kinetic energy).

Combustion thermodynamics explains these processes. Thermodynamics and combustion chemistry (chemical reaction kinetics and equilibrium) combine to provide the theory required to calculate performance behavior of engine designs and to analyze rocket test data. Rocket propulsion is mainly about combustion thermodynamics and is the basis for rocket engine design and analysis.
