Why will a star with a large mass radiate more energy into space and appear hotter and brighter than a star with a smaller mass?

Because the larger mass means more core pressure, making fuel (hydrogen turning into helium) burn faster and more frequently, resulting in a hotter, brigher star. A small mass star has less fuel and internal pressure, so it generates less light and is red in color. A medium star like our sun burns moderately, and is yellow.
The H-R Diagram places these stars in spectral classes, from biggest and hottest to smallest and dimmest, and the orders are O, B, A, F, G, K and M. We are a type G star.
Think of a fire; the more fuel you put on it, the hotter and brighter it blazes and it can become white-hot if it is a very intense fire. As the ashes burn down, the fire is smaller, dimmer and the coals appear red, which is cooler.
The principle is the same with stars; the bigger and hotter they are, the brighter they burn but they have shorter lives than do moderate and small stars.

Why electrons does not radiate energy?
It cannot radiate because it cannot remain single but joins with a positive ion or proton.
Do hotter stars radiate more energy at higher frequencies?
yes, they do!
According to Bohr's theory what would an excited atom do?
radiate energy
What will cause magnesium to glow brighter?
Increasing the temperature of magnesium will cause it to glow brighter. Heating magnesium to a high temperature excites the electrons in the atoms, causing them to jump to higher energy levels. As the electrons return to their lower energy levels, they release energy in the form of light, resulting in a brighter glow.
If you double the Kelvin temperature of a hot piece of steel how much more energy will it radiate per second?
twice as much
What objects can radiate energy?
All objects radiate energy at a rate depending on their temperature.
Does a drum set radiate sound energy?
Yes, a drum set can radiate sound energy when the surface of the drum vibrates on striking it to set particle molecules in air to transfer energy in a wave form and radiate out.
What is the meaning of pulsar?
radiate energy
Does the sun radiate both visible energy and invisible energy?
yes.
Why electrons does not radiate energy?
It cannot radiate because it cannot remain single but joins with a positive ion or proton.
Does the sun radiate visible and invisible energy?
Yes.
Radiation transfers thermal energy by?
thermal energy will always radiate to lower energy matter.
What is the definition of the word 'radiate'?
The definition of 'radiate' is to emit energy in the form of waves or rays. More specifically, 'radiate' also refers to energy being released in heat, gas or light form. Synonyms of the word include 'beam' and 'emit'.
When excited electrons radiate energy the amount of energy given off is equal to?
Photons
What is the connection between a star's surface temperature and its color?
Stars that are cool normally radiate ther energy in the electromagnetic spectrum as red. Even though all the sky appear to be white, Hot stars radiate much longer wave lengths, causing an almost blue color to be emitted.
In polar regions ions radiate radiate energy as shimmering lights called?
Aurora borealis; the Northern Lights.
What energy source radiates energy on and off?
like a blinking stop light these enormous energy sources radiate energy on and off
