Can gas giants turn into stars?
Can gas giants turn into stars? Stellification is a theoretical process by which a brown dwarf star or Jovian-class planet is turned into a star, or by which the luminosity of dim stars is greatly magnified. What happens when two gas giants collide? The pieces would tend to either fall back down, or remain in […]
Do solid metals conduct electricity?
Do solid metals conduct electricity? Metals conduct electricity both when solid and when molten. This is because the delocalised electrons are mobile. Covalently bonded substances with a simple molecular structure do not conduct electricity. This is because they have neither ions nor electrons that are mobile. How do you know if a solid will conduct […]

What is the evidence of nebular theory?
What is the evidence of nebular theory? What Evidence do we have of a Nebular Theory-type development? We have observed discs of gas and dust around other stars. We can also see evidence of stars and planets forming in clouds of gas and dust; young planet systems in the making are called Proplyds. What is […]

What is constant acceleration equal to?
What is constant acceleration equal to? If the velocity of the particle changes at a constant rate, then this rate is called the constant acceleration. For example, if the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 2 m/s to 5 m/s over one second, […]
Is color blindness a single gene disorder?
Is color blindness a single gene disorder? Colour blindness is a usually a genetic (hereditary) condition (you are born with it). Red/green and blue colour blindness is usually passed down from your parents. The gene which is responsible for the condition is carried on the X chromosome and this is the reason why many more […]
