Fusion reactions decrease the overall number of particles in the core, causing the core to shrink, converting gravitational potential energy into thermal energy, and increasing the rate of fusion.

What is the critical temperature the core must reach for a star to shine by fusion?

The critical temperature for nuclear fusion in a star's core is around 10 million degrees Celsius. At this temperature, hydrogen nuclei can overcome their mutual repulsion and fuse to form helium, releasing energy in the process. This energy production is what causes a star to shine.


How does the sun produce heat and light energy?

Stars must be formed by the agglomeration of material under gravitational forces. When the mass of material is high enough the pressure in the mass will get to the point where it causes enough heat to start a nuclear fusion reaction, which then goes on producing heat for billions of years.


How do you list the life cycle of a star with the same mass as your sun is in order?

First you have the birth , childhood , midlife and then death our sun is beleived to be in the process of just starting midlife so we got a couple million years left to enjoy it and then we must flee .


What is the worlds oldest thing?

The oldest thing in the world is considered to be the universe itself, estimated to be about 13.8 billion years old according to current scientific theories. Other ancient things include certain rocks and minerals on Earth that date back billions of years.


Can a star have less than half the mass of the sun?

No, a star must have a minimum mass of about 0.08 times the mass of the Sun in order to sustain nuclear fusion in its core and qualify as a star. Stars with less mass are known as brown dwarfs and do not undergo the same fusion processes as stars.

Can you summon a elemental hero neos fusion by sending cards from your hand?

No, the 'Neos' fusion monsters state how they must be summoned on their cards. The monsters must be returned from field to deck, you can't summon them like regular Fusion monsters using a fusion card and components in hand.

If nuclear fusion is so effective for powering stars why isn't it pratical for generating electricity in power plants?

Nuclear fusion in stars is quite slow; typically the star exhausts its entire fuel supply in millions, billions, or even trillions of years. To make it practical on Earth, temperatures and pressures must be achieved that are quite a bit higher than those in the cores of stars. But even the pressures and temperatures in the cores of stars are hard to achieve - we are talking about temperatures of several million degrees, as well as very high pressures. For example, no regular container can withstand such a temperature.


Can you fuse gladiator beast from your hand?

No. Gladiator Beasts must be on the field to Contact Fuse. When the appropriate Fusion Materials are on the field, you can return them to your Deck to Fusion Summon the appropriate Gladiator Beast Fusion Monster.


Can you fuse monsters and summon the Fusion to the field in Yu-Gi-Oh?

If you activate polymorization, then yes you may fuse monsters in your hand, or on the field. You must also have the correct fusion monster in your fusion deck.

Can you use polymerization to create a NEW fusion monster or not?

Polymerization is used to Fusion Summon Fusion Monsters from your Extra Deck in Yu-Gi-Oh!. You do not create a "new" monster out of thin air. You must have included the Fusion Monster you are trying to Summon in your Extra Deck. You must also fuse the monsters that are listed on the Fusion Monster.To Fusion Summon a Fusion Monster, you activate Polymerization (unless specifically stated otherwise, such as on XYZ-Dragon Cannon) and send the appropriate Fusion Material Monsters to the Graveyard (from your Hand or your side of the field). Once this criteria is met, place the appropriate Fusion Monster on the field in face-up Attack or Defense Position. Note that this is treated as a Fusion Summon.PolymerizationSPELL/NormalSend Fusion Material Monsters that are listed on a Fusion Monster Card from your Hand or your side of the field to the Graveyard, and Special Summon that Fusion Monster from your Extra Deck.
