Depending on how high the pressure is, they both can have the same maximum temperature. After a while, they become a different type of phase called a supercritical fluid.

biofuels
Solid fuel: coal, wood Liquid fuel: kerosine, gasoline Gas fuel: methane, hydrogen
A fuel with an ignition temperature less than the room temperature would spontaneously ignite - it would not be suitable for fuel because it would burn itself up before it could be used to power an engine.
Rockets typically use Liquid oxygen and liquid hydrogen for fuel. I suspect this is what you are asking. I know of no rocket that uses liquid nitrogen.
Petrol, or gasoline, at standard temperature and pressure is a liquid.
200 degrees
the fuel produces has higher ignition temperature and produces more heat
90 degrees is the maximum velocity for diesel. Diesel is generally any liquid fuel used in diesel engines within vehicles.
For one, they have a higher BTU output and higher constant flame temperature than unleaded fuels. In liquid form, they're less volatile and less flammable than unleaded fuels, but ignite easily when vaporized.
Diesel fuel has different chemical and physical characteristics than regular petrol. It is fractioned at a higher temperature and has a higher flashpoint.
The highest heat release of any fuel is that of hydrogen at 62,000 btu / lb. or ~34,445 calories/gram.
I would think not. The temperature differential could fracture the fuel rods, and you don't want that.
All substances have a liquid form, but may not be present in nature. Under extreme pressure and temperature circumstances, liquid oxygen can be created, in fact, it is used to fuel space rockets.
liquid Hydrogen + liquid Oxygen
liquid fuel
All of them. Heat and/or oxygen are removed by the water on the surface of the burning fuel. Water also raises the ignition temperature of the fuel, thus breaking the chain reaction when there is no longer enough heat to continue burning the wet fuel.
