When a Star is is undergoing nuclear Fusion, for example our Sun, at this moment it is Fusing Hydrogen to Helium, this creates outward thermal energy, but the gravity at the core stops the Sun from expanding, this is called equilibrium, where gravity is equal to outward force. However when the Sun runs out of Hydrogen, Nuclear Fusion will cease and the gravitational pull of the core will lessen, allowing for the sun to expand. Eventually the core will contract under its own gravitational pull and Bamb fusion will take place again. This time converting helium to carbon. Gravity will again be maintained and again equilibrium will be restored, though this time our sun will be Slightly bigger and cooler. This will go on and on over many cycles. Each time getting larger and cooler until fusion can no longer take place.
A subgiant star is bigger than a neutron star. Neutron stars are incredibly dense and compact, with a radius of about 10-15 kilometers, while subgiant stars have a larger radius of several million kilometers.
A subgiant star is larger than a neutron star. Neutron stars are incredibly dense and compact remnants of massive stars, while subgiant stars are in a transitional phase between main sequence and red giant stages, typically larger and more diffuse than neutron stars.
It can break the glassware, especially if it expands while being heated.
When air expands, its pressure decreases while its temperature decreases simultaneously. This is due to the decrease in density as the air molecules move further apart, resulting in lower pressure. The decrease in pressure causes the air to do work on its surroundings, leading to a drop in temperature through the expansion cooling effect.
Venus Venus is called the Evening Star and it happens in the couple of months before inferior conjunction. Venus's orbit is inside ours so it goes quicker and while it is catching us up it appears in the evening sky before and after sunset. While that is happening it's getting closer to us all the time, becoming brighter and brighter. Eventually it moves quickly in front of the Sun and disappears. A few weeks later it reappears the other side as the Morning Star before and after dawn. You can see all this happening if you wait until the autumn of 2013.

The internal pressure of the gasses inside a balloon remains constant while external air pressure decreases as the balloon ascends. As the balance between the two changes, the pressure inside becomes progressively greater than the pressure outside, so the balloon expands. If it expands beyond the ability of the balloon material to contain it, the balloon will burst.
Rastaban is a binary star system in the constellation of Draco. The primary star is a yellow-white subgiant, while the secondary star is most likely a red dwarf.
On 13 January 2010, while the floods are happening in Queensland, it is indeed raining in Melbourne.

while means when it is happening. repeat means to do again

When a balloon is pierced with a pin, the sudden pressure from the sharp object creates a small tear in the balloon's thin material. This tear rapidly expands due to the high pressure inside the balloon, causing the balloon to burst.
The answer is fairly simple, while some believe that a balloon bursts when near hot air because the balloon simple melts, it actually has to do with the pressure inside the balloon. When near hot air, the air inside the balloon expands slightly, causing a change in pressure, and causing the balloon to burst.
Nothing.The correct phrase is "on this occasion" and just means "when this is occurring" or "while this is happening." An occasion is just a happening or event.
