Is a glowing neon sign a physical change?
Yes, a glowing neon sign represents a physical change because the neon gas inside the sign undergoes a change in energy state to emit light. This change is reversible and does not alter the chemical composition of the neon gas.
How does the Jeans mass determine the formation of a star when a sound wave travels through a gas cloud?
The Jeans mass is the minimum amount of mass needed for a gas cloud to collapse and form a star. When a sound wave travels through a gas cloud, it can cause the cloud to become unstable and collapse if its mass exceeds the Jeans mass. This collapse leads to the formation of a star.
What A nebula is a cloud of dust and gas loosely held together by gravity?
A nebula IS a cloud of dust and gas loosely held together by gravity.
What is a cloud a solid a liquid or a gas?
A cloud is a form of gas it is made of small particles which are quite far apart you can turn liquids into gasses buy heating them (condensation)
How does the density of a spherical gas cloud of 105 solar masses and 10 parsecs in radius compare to the density of water?
The density of water, at one atmospheric pressure, is approx 1000 kg/m3. The density of the gas cloud is 1.89*10-22 kg/m3 which means the cloud is approx 1.9*10-25 times (190 octillionths) as dense.
What do you call a glowing cloud of gas?
Nebula
What is the name of a glowing cloud of gas that starts with n and ends with a?
Nebula
What is a cloud of gas that is known as the birthplace of stars?
A nebula is a cloud of gas and dust in space where new stars are formed. These regions are often characterized by the presence of young, hot stars surrounded by glowing gas and dark dust.
What is a spinning cloud of gases?
A spinning cloud of gases typically refers to a phenomenon in space where gases, such as hydrogen and helium, are coalescing due to gravitational forces. This process can lead to the formation of stars or planets as the spinning cloud of gases slowly collapses and heats up.
What are the glowing clouds in space?
The glowing clouds that you see in pictures from space are called emission nebulas. A emission nebula is a cloud of hot, glowing cloud of gas and dust in space. These nebulas absorb the light of nearby stars and reach very high temperatures. The high temperature causes them to glow. Emission nebulas are often found in regions of space where new stars are forming.
Is a star a glowing sphere of hot gas?
Yes, a star is a glowing sphere of hot gas.
What gas re lights a glowing splint?
OXYGEN RELIGHTS A GLOWING SPLINT Oxygen.
What is a large cloud of gas and dust from which stars are formed?
A large cloud of gas and dust from which stars are formed is called a nebula. Within a nebula, gravity causes the gas and dust to come together, forming clumps that eventually collapse to create new stars. Nebulae are often seen as glowing or dark patches in the night sky.
What is a nuees ardantes?
A superheated incandescent cloud of gas and ash that swiftly travel down the volcano like an avalanche (also known as "the glowing cloud"). Scientifically, they are called pyroclastic flows or pyroclastic density currents.
Oxygen gas will what a glowing splint?
Oxygen will rekindle or relight a glowing splint.
What is produced when the outer parts of a star explodes after the core collapses?
The explosion (a supernova) produces a glowing cloud of gas (called a nebula) that slowly expands and dissipates (eg the crab nebula).
What is the difference between a planetery nebula and a nebula?
A cloud in outer space consisting of gas or dust and planetry nebula is one of the types also called ring nebula or A planetary nebula is an emission nebula consisting of a glowing shell of gas
