Colder. Currently there is a background radiation, a residue from the Big Bang, at a temperature of about 3 Kelvin; that radiation used to be much hotter in the early Universe.

What happens to the luminosity of stars in the main sequence as temperature decreases?

In the main sequence, as the temperature of a star decreases, its luminosity also decreases. This relationship is explained by the Stefan-Boltzmann Law, which states that a star's luminosity is proportional to the fourth power of its temperature. Therefore, cooler stars emit less energy and light compared to their hotter counterparts. As a result, lower temperature main sequence stars, such as red dwarfs, are significantly less luminous than hotter stars like blue giants.


Why do crystals of snow formed from a snow making maching even though the temperature of the mixture of water and air may be well above the freezing temperature of water?

The water molecules expand when they are blown out. When this happens, the mixture turns into snow.


Which are more common low or high temperature stars?

Low-temperature stars, such as red dwarfs, are more common in the universe than high-temperature stars. They constitute the majority of stars in our galaxy, primarily due to their long lifespans and the fact that they form more frequently. High-temperature stars, like O and B types, are relatively rare and have shorter lifespans, which contributes to their lower abundance. Overall, the prevalence of low-temperature stars significantly outweighs that of high-temperature stars.


Do liquids expand uniformly with rise in temperature?

No, liquids do not always expand uniformly with temperature. Generally, liquids expand as they are heated, but the expansion may not be uniform due to factors such as the specific properties of the liquid and the conditions under which it is heated.

What happens when a door expands?

A door expand when the wood absorb water and during variations of the temperature.


What happens as stars die?

Exactly what happens depends on the mass of the star. Low mass stars first expand into giants, then shrink to white dwarfs. Stars with a little more mass than the Sun end up as neutron stars; stars with considerably more mass with the sun end up as black holes.


Do stars expand in size?

Stars expand in size to become red giants, when they start running low on Hydrogen fuel.

The hotter the star, the brighter. Ex: A stove


What happens to the molecules of water when the temperature of the water increases?

When the temperature of water increases, the molecules of water move faster and farther apart, causing the water to expand and eventually turn into steam.


What happens to the ball as column A gets heated?

As column A gets heated, the ball will likely expand or increase in size due to the increase in temperature.


What happens to the volume of Balloon left on a sunny windowsill?

It would increase. The balloon would expand because when temperature increases, volume increases as well.


Do solids expand at the same rate?

No all solids do not expand at same rate because some solid expand at less temperature and some solids expand at less temperature. For example if we take iron and plastic iron expands at high temperature and plastic melt at less temperature(at candle light also).
