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 a stars nuclear energy generation change if the core decreases in temperature?
What happens to a stars nuclear energy generation change if the core decreases in temperature?
Describe what happens to air temperature when work is done on the air to compress it?
Yes. As the molecules become closer, the collisions increase, increasing temperature.
What do blue stars expand to become?
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.
Will an inert gas expand and contract with temperature?
It will contract.
What happens to a stars nuclear energy generation change if the core decreases in temperature?
What happens to a stars nuclear energy generation change if the core decreases in temperature?
What happens to air temperature when it is compressed or allowed to expand?
Heats with compression, cools with expansion.
What happens when a door expands?
A door expand when the wood absorb water and during variations of the temperature.
What is it when something absorbs heat?
What happens is that the molecules will move faster causing the object's temperature to increase and expand.
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.
What happens to brightness as surface temperature of the main sequence stars increase?
The hotter the star, the brighter. Ex: A stove
Describe what happens to air temperature when work is done on the air to compress it?
Yes. As the molecules become closer, the collisions increase, increasing temperature.
What causes a substance to expand?
An increase in temperature of the substance causes it to expand.
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).
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.
What do blue stars expand to become?
Blue giants.
