What happens to the temperature of main sequence stars as the brightness increased?
Wiki User
∙ 8y ago
Brightness is a value of luminosity verses distance as viewed from a point.
From Earth, the luminosity of a star is it's apparent magnitude, whereas absolute magnitude is it luminosity as viewed from a set point (for stars this value is about 32 light years).
Because of this a star can loose temperature but gain in diameter and appear brighter, in contrast a star can contract and thus shrink, but heat up and appear brighter.
Brightness is related to temperature, not the other way around.

What happens to temperature if albedo is increased?
A decrease in radiative equilibrium temperature
What happens to the temperature and humidity in a cold front?
Temperature is lowered. Humidity is increased in a cold front.
What happens to the rate of dissolution as the temperature is increased in a gas solution?
The rate decreases.
What happens to the movement molecules when their temperature is raised?
They begin to move faster. The increased temperature increases the energy of the molecule.
What happens when the temperature of a gas increased?
If you increase the temperature of a gas, its particles (atoms or molecules) will speed up. If it is in a closed container, the pressure will also increase.
What happens to brightness as surface temperature of the main sequence stars increase?
The hotter the star, the brighter. Ex: A stove
What happens to the brightness of main sequence stars as they get hotter?
As they get hotter, they usually get brighter.
What happens when the temperature of a forward biased diode is increased?
What happens depends on the temperature coefficient of the diode. If that diode has a positive temperature coefficient, it resistance increases with increased temperature. A diode with a negative temperature coefficient does the opposite.
What happens to temperature if albedo is increased?
A decrease in radiative equilibrium temperature
What happens of the speed of the particles if the temperature is increased?
It increases.
What happens when the temperature of substance is increased?
The solubility of solids in water increases with the increasing temperature.
What happens to an objects temperature when you add heat?
its temperature is increased and if temperature supplied continously phase change can be changed
What happens to the pressure of gas if the temperature of the gas is increased?
The pressure of a gas increases with an increase in temperature.
What happens to the pressure of the gas if the temperature of the gas is increased?
The pressure of a gas increases with an increase in temperature.
What happens to the temperature and humidity in a cold front?
Temperature is lowered. Humidity is increased in a cold front.
What happens to a gas when the temperature of the gas is increased?
The volume increases Source:
What happens to temperature if the average motion of particles is increased?
It goes up.
