At 15.6 million degrees Celsius the temperature of the Suns core is high enough for nuclear what to occur?
For nuclear fusion.
How hot is a nova?
The corresponding white dwarf needs to reach a temperature for nuclear fusion to occur, which is about 20 million degrees kelvin.
What is the average temperature of the sun?
The temperature varies on different parts of the Sun. For rexample, the visible part (photosphere) has a temperature of almost 6000 degrees Celsius, while the nucleus is estimated to be 15 or 16 million degrees.
A fragment of a collapsing gas cloud that comes to equilibrium with a central temperature of 4 million k becomes what?
The gas cloud will become a brown dwarf because it did not make the 10 million kelvin in order to start nuclear fusion. :)
What is the critical temperature the core must reach for a star to shine by fusion?
about 10500-11000k is when fusion commences which creates the shining of the star
What is the temperature which fusion of hydrogen into helium begins?
Fusion requires temperatures about 100 million Kelvin
What temperature is required for fusion to happen?
In tokamak reactors, approx 300 million degC
At what temperature do star begin the process of nuclear fusion?
Between 10 and 15 million degrees.
At 15.6 million degrees Celsius the temperature of the suns core is high enough for nuclear to occur?
fusion
At 15.6 million degrees Celsius the temperature of the Suns core is high enough for nuclear what to occur?
For nuclear fusion.
How can temperature either help fusion to occur or prevent fusion from occurring?
How can temperature either help fusion to occur or prevent fusion from occurring?
Nuclear reactions at very high temperature is known as?
You probably mean nuclear fusion
How hot is a nova?
The corresponding white dwarf needs to reach a temperature for nuclear fusion to occur, which is about 20 million degrees kelvin.
How do scientists hope to use lasers in nuclear fusion?
TO initiate fusion process very high temperature of the order of 100 million kelvin is needed. Such a high temperature could be produced by laser beam if it is used in a different technique. That is why sciectists rely on laser.
What is meant by nuclear reaction at very temperature?
there is no end-scale "highest" temperature, to put this in easy terms : the bigger the bang the higher the temperature, to answer the Question: the highest temperature would probably be the temperature created when the big-bang occurred.
How hot does a fusion reaction have to be?
The basic answer is that nuclear fusion can only occur at VERY high temperatures like MILLIONS of degrees. You can relate it to the sun where the sun is around 10mil degrees and bonds hydrogen atoms to form helium.
What is the average temperature of the sun?
The temperature varies on different parts of the Sun. For rexample, the visible part (photosphere) has a temperature of almost 6000 degrees Celsius, while the nucleus is estimated to be 15 or 16 million degrees.
