stars generally use hydrogen as fuel during the most part of their lifetimes. The hydrogen atom fuse together under the immense temperatures and pressures to produce helium atoms. This is a nuclear fusion reaction that in itself produces vast amounts of energy.

Which spectral type of star spends the least amount of time on the main sequence?

O, because O stars are the hottest, so they use their energy faster than the lower stars.


Which type of stars will most likely use up its nuclear fuel soonest?

Massive stars are more likely to use up their nuclear fuel the soonest. They burn fuel at a much faster rate due to their higher temperatures and pressures, resulting in shorter lifespans compared to smaller stars like our Sun.


What is the main fuel in stars if any?

In our solar system both the gas giants Jupiter and Saturn, and the ice giants Uranus and Neptune (sometimes also called gas giants) are believed to have rocky cores, likely composed of silicates, ice, and possibly heavier elements like metals such as nickel/iron although their true composition is not well known. Above that are deep layers of metallic hydrogen. Their atmospheres are predominatly molecular hydrogen and some helium, with other compounds such as ammonia present in small amounts on Saturn. The ice giants Uranus and Neptune are so named for having much more icy compounds such as water, ammonia, and methane, and some nitrogen and hydrocarbons. The presence of methane in outer layers is thought to give Neptune its blue color.


What are the two main types of rockets?

The two main types of rockets are liquid fuel rockets, which use liquid propellants like liquid oxygen and kerosene, and solid fuel rockets, which use a solid mixture of fuel and oxidizer. Liquid fuel rockets offer more control and efficiency, while solid fuel rockets are simpler in design and more reliable.


Do space shuttles use fuel?

Space shuttles use fuel when taking off and for control while in orbit, deorbiting, and landing. The main takeoff engines use liquid hydrogen and liquid oxygen, and there are two solid-fuel rocket boosters. In orbit, the shuttle uses thrusters that burn hydrazine and nitrogen tetroxide.

What is one main use for natural gas?

One main use for natural gas is as a fuel for heating homes and buildings. Natural gas is burned in furnaces or boilers to generate heat and provide warmth during cold weather.


Fuel-cell automobiles use gas as a fuel?

No, fuel-cell automobiles do not use gas as a fuel. They use hydrogen gas as a fuel source, which is converted into electricity to power the vehicle.


What is the primary use of natural gas?

The primary use of natural gas is for generating electricity. It is also used as a heating fuel for homes and businesses, as a fuel for industrial processes, and as a feedstock for the production of chemicals and fertilizers. Additionally, natural gas is increasingly being used as a transportation fuel in the form of compressed or liquefied natural gas.


Why do the most massive stars on the HR diagrahm have the shortest lifespans on the main sequence?

Because they use up more fuel faster


What is the main function of methane gas?

The main function of use of methane gas is that it is the main constituent of the natural gas which is used as a fuel in automobiles and for domestic uses as well. It is very clean and also provides a high calorific value.


What is the main use of natural gas?

Can you replace the solid fuel with gas fuel?

i think that we can use gas fuel instead of solid fuel to save money.


What are the main differences between a propane stove and a natural gas stove?

The main differences between a propane stove and a natural gas stove are the type of fuel they use and the pressure at which the fuel is delivered. Propane stoves use propane gas stored in tanks, while natural gas stoves are connected to a gas line in the home. Propane is delivered at a higher pressure than natural gas, which affects the size of the burner flames and the heat output of the stove.


Did the b-36 jet engines use jet fuel or the same gas as the 4360 engines?

Why do you use methine?

Methane is the main component of natural gas. Methane in its natural state is found under the sea floor and below the ground.Some of its uses are: cooking fuel, rocket fuel, and to convert water and carbon dioxide into gas.


What are the main differences between a propane and gas stove?

The main differences between a propane and gas stove are the type of fuel they use and the way they are connected. Propane stoves use propane gas stored in tanks, while gas stoves are connected to a natural gas line. Additionally, propane stoves tend to be more portable and can be used in areas without a natural gas supply.
