There are two main types of rockets: liquid-fuel and solid-fuel. Liquid-fuel rockets consist of a fuel and oxygen (or other oxidizer) in liquid state. They are combined in a combustion chamber and ignited. The fuel flow to the engine can be controlled, the amount of thrust produced can be regulated and the engine can be turned off or on as needed. Solid-fuel rockets consist of a fuel and oxidizer that are pre-mixed in a solid form. Once the solid fuel is ignited, the resulting thrust cannot be regulated or turned off. This fuel system is simpler, safer, and cheaper-but less efficient-than that of a liquid-fuel rocket.
solid rockets use blackpowder to propel the rocket, while water (and pressure) propels liquid rockets
Liquid fueled rockets get it from liquid oxygen, and solid fueled rockets get it from and oxidized metal.
The two main types of rockets are, Solid Fuel and Liquid Fuel
The three kinds of rockets are solid fuel rockets, liquid fuel rockets, and ion powered rockets.
unlike solid fuel, liquid fueled rockets are capable of being throttled, shut down, and restarted.
Liquidcan be throttled. Solids can't. Liquid can be restarted (turned off and on again). Solids can't.
The Shuttle uses both. The outer rockets on the main body are aluminum oxide. Once lit you are on. In the big container sits a lot of separated liquid Oxygen and liquid Hydrogen. When mixed at the output nozzles, a steerable, controllable jet of very hot water is let go. The difference being solid rockets go on then off. The liquid ones are controllable.
is there a chemical difference between the solid and liquid states of nitrogen
Liquid fueled rockets get it from liquid oxygen, and solid fueled rockets get it from and oxidized metal.
What is the difference between solid and gas in terms of their fluidity
A solid and liquid have the same mass if the amount is the same.
it's the comparison between the fuels used, solid / liquid
temperature
A solid fuel rocket engine is just what it sounds like. The fuel inside the rocket is completely solid. In a liquid fuel rocket the fuel is a liquid. Bottle Rockets that you can buy in many stores are fueled with Solid Fuel. Most liquid fuel rockets contain 2 different types of fuel. Once that fuel is mixed and ignited you get your thrust.
the only difference is the energy of the atoms
The atoms in a solid are in a tighter formation that as they are in a liquid. In a liquid, They are loose and have the ability to pour.
The molecules in a solid vibrate in place. The molecules of a liquid are moving about.
The earliest rockets--i.e., those built by the Chinese as early as the 14 century--used solid fuel.
