Do fusion reactions occur at a slower rate?

Do fusion reactions occur at a slower rate?

Fusion reactions happen at a slower rate: in smaller stars than in bigger ones. A stellar wind consists of the debris that is exploded out of a star as it “dies.”

Which of the following can be said about large stars?

Which of the following can be said about large stars? Large stars have a shorter lifetime than smaller stars. helium isotopes, protons, and gamma rays. Approximately how long does it take the energy of the Sun to be transferred from the stellar core to the photosphere?

Do all stars explode cataclysmically?

Stars: all explode cataclysmically when they die and contribute their matter to future star generations. that are the size of our Sun will burn for about 10 billion years. begin as protostars, which fire up when they collapse and become denser and hotter.

Which of the following methods of heat transfer occurs when an increase in temperature creates a decrease in density?

Convection
Convection is driven by the large scale flow of matter in fluids. Solids cannot transport heat through convection. Natural convection is driven by buoyant forces: hot air rises because density decreases as temperature increases.

Do fusion reactions occur at a slower rate in hotter stars?

Fusion reactions happen at a slower rate in bigger stars than in smaller ones. False: Large stars, because of their greater mass, become denser and therefore hotter than small stars; fusion reactions are accelerated, and the large stars burn out faster.

Why do massive stars have shorter life spans than average stars?

A star’s life expectancy depends on its mass. Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years.

Why do some stars appear brighter than others?

A star’s brightness also depends on its proximity to us. The more distant an object is, the dimmer it appears. Therefore, if two stars have the same level of brightness, but one is farther away, the closer star will appear brighter than the more distant star – even though they are equally bright!

When an increase in temperature creates a decrease in density?

When temperatures increase, objects expand and become larger and therefore the density decreases. When temperatures decrease, objects condense and become smaller so density increases.

Why do larger stars burn out faster than smaller stars?

Fusion reactions happen at a slower rate in bigger stars than in smaller ones. False: Large stars, because of their greater mass, become denser and therefore hotter than small stars; fusion reactions are accelerated, and the large stars burn out faster.

Which is the process by which stars produce heavier elements?

Stellar nucleosynthesis: A. is the term for the process by which stars create the heavier elements. B. produces elements up to atomic number 26 (iron) in low-mass stars like our Sun. C. is a normal process that happens during the life cycle of stars. D. reactions vary and are dependent on the mass of the star.

How often does carbon production take place in stars?

Carbon production required the temperatures and subsequent particle velocities of stellar nucleosynthesis in at least first-generation stars. completes one rotation around the center of the Milky Way every 250 million years. create elements by fusing the nuclei of small atoms into the nuclei of larger atoms.

What kind of stars form in a supernova?

Very large atoms, with atomic numbers greater than iron, generally form in a high-mass star and are disbursed by its “death” as a supernova explosion. Only high mass-stars consist of atoms large enough to combine and produce very large atoms, and they are the only stars to supernova at their “deaths.” (Section refs: 1.5, p.
