As a black hole becomes more massive, its event horizon expands. No one knows what happens inside the event horizon. Many have advanced different speculations. We know it retains mass and angular momentum.
Yes. As they swallow matter, the black hole can get bigger and bigger.
well black holes grow when they suck up or absorbe more matter etc.
No. A black hole is as collapsed as something can get. Current modelling suggests that all mass in a black hole is contained in an infinitely dense point called a singularity.
Yes
First you will need a large area of space. Next, you will need a Neutron star that is about to die. You will probably need a planet/star if you want to see a black hole consume it. After getting everything, go far out as you can to watch. The neutron star will expand and strange things will happen. The star will expand. Then two gamma ray bursts will appear at both sides of the star. Soon the black hole inside the star will eat the star up and now you will have a black hole. Then the black hole will eat the planet that you put next to it. It will look weird because the immense gravity of the black hole will alter the light around it. The planet/star will be a line. Run away as fast as you can unless you want to die.
Our Sun will never become a black hole. It does not have enough mass and thus pressure to initial the sequences required to form a black hole. In about 5 billion years time, our Sun will slowly expand into a red giant, a billion years later it will shed it's outer envelope leaving nothing more that a very hot white dwarf about the size of the Earth. Not that we will be around to see it.
The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.
No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.
A black hole is a type of star with excessive gravity. Here are some sentences.The star was sucked into the black hole close by.A black hole will even absorb light.The scientist is studying a black hole.
No. If no matter enters a black hole it will actually slowly lose mass and shrink via Hawking radiation. A black hole will gain mass if matter fals into, which will cause the event horizon to grow.
it may expand and swallow and swallow us.
No. It simply doesn't work that way.

Stars want to expand when they are active, but their high gravity keeps them the right size. When stars are too old they stop expanding, and its gravity makes it very small. If an object has too much mass for its size, it is a black hole.
The collapses star gets squeezed by collapses gas and turns into a black hole.
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

A black hole originated as a star, that is, the star converted to a black hole.
The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.
If you fall into a black hole, you'll go into the black hole and nowhere else.
