What process does stars convert mass in to great amounts of energy?
gravitational pull
What star is densest?
The densest stars are neutron stars; these are "dead stars", in the sense that they ran out of fuel and no longer convert energy. However, they still have a large amount of energy left over from the collapse, which they gradually emit.
Why are lower-mass stars unable to ignite more massive nuclear fuels such as carbon?
Low-mass stars have little gravitational energy, so when they contract, they don't get very hot.
A star generates energy by?
Nuclear fusion. Most stars (the so-called "main sequence" stars) convert hydrogen-1 into helium-4.Nuclear fusion.

What do high mass stars and low mass stars have in common?
They produce light.
What process does stars convert mass in to great amounts of energy?
gravitational pull
Can you convert energy into mass?
No. Mass and kinetic energy are not the same thing.
How do you convert Mass into thermal energy?
You generally need a catalyst or a mechanism to convert the energy. For example to convert fuel (a mass) into thermal energy, oxidizer and a spark are needed.
What did Einstein propose about stars?
its not about stars its about mass and he proposed that mass can be converted into energy
Does burning wood violate the law of conservation of energy?
No, nothing can violate the law of conservation of energy, it's a law! Energy can convert to mass, and mass can convert to energy, but the overall total of mass and energy in the universe is constant.
How fast is the sun making nuclear fusions?
Fast enough to convert 4 million tons of mass to energy, every second.Fast enough to convert 4 million tons of mass to energy, every second.Fast enough to convert 4 million tons of mass to energy, every second.Fast enough to convert 4 million tons of mass to energy, every second.
How do you convert energy transferred per gram into energy transferred per mole?
Convert grams into moles. To do so, you divide mass by the molar mass of the substance.
How does the CNO cycle differ from the proton-proton chain?
The CNO cycle, which stands for carbon-nitrogen, is one of the processes b which stars convert hydrogen to helium. This is the dominant source of energy for stars with larger mass.
Can you convert energy in to mass or mass into energy?
No. Nor can you convert mass into energy. In any reaction - including nuclear reactions - both the amount of mass and the amount of energy remain the same, before and after the reaction. For example, the energy that escapes from a nuclear reaction also has a corresponding mass. On the other hand, the energy existed before the reaction as well, in the form of (nuclear) potential energy.
Which device transforms mechanical energy into electrical energy and why a. generator b. motor c. transformer mass spectrometer d. d. mass spectrometer?
generators which convert mechanical energy to electrical energy and motors which convert electrical energy to mechanical energy
What do atoms convert mass in to?
The mass can be converted in energy: the equation of Einstein is: E= mc2.
Why can't a star last forever?
Because they convert their materials into energy and energy = mass.
