Is cardon dioxide matter?
A matter is a "thing" that has mass and occupies space so theoretically carbon oxide is mattar as CO2 has mass (you can measure the weight) and occupies space (for example you blow in a balloon and it expands)
Which phase of the matter has no definite volume and occupies all the space available to it?
Gas.
Matter occupies space and has what?
Matter does.
Does water contract when cold?
No, it expands- this is because when the particles in the water are heated they move around and cause the water to expand. When water is cooled it contracts. This is because the particles in the water and coming together. When water is cooled it usually becomes ice or expands a little. The volume of ice is 4x greater than water, therefore it actually expands, rather than contracting.
When a person exhales what happens to the diaphragm?
The diaphragm muscles contract and relax pulling the diaphragm down and then releasing it. When we inhale, our diaphragm muscles contracts and flattens. When we exhale, they relax and arch upwards.
Why does gas have a definite mass?
It doesn't, it expands and contracts in the space it has.
How does a liquid thermometer measure temperature?
The alcohol or mercury in a thermometer expands or contracts very precisely according to heat or cold.
Is matter being transformed into space by black holes?
No, when the big bang happend dark matter and dark energy came. Dark matter expands space even as we speak.
Why concrete roads have gaps?
because it expands and contracts depending on the temperature..the gaps allow the concrete some space to expand so that it will not crack..
What changes takes place in the liquid inside a thermometer when the thermometer is placed into something hot?
The liquid in thermometers expands when temperature increases (and contracts when temperature decreases). When it expands, the only place for it to expand 'to' is up the thermometer (into the empty space above it).
How can you prove air is matter?
The classical definition says anything that occupies space is matter. To prove air occupies space we can do a small experiment. Take a balloon and blow air in it. The balloon expands and this proves that air occupies space. And thus we can prove air is matter.

What was the method of achieving warp speed in Star Trek?
The method for achieving warp speed in Star Trek is to warp the space around the vessel and leave the vessel in a pocket of normal space. It contracts space time in front of the vessel and expands the space time behind it.
Is air matter how can you tell-?
Yes it is, because when you blow air into a balloon, the balloon expands meaning it takes up space.
What theory states that the universe started as a ball of matter which expands and still expanding?
No such cosmological model exists. What you relate e is one description of Big Bang Cosmology (BBC), but that description is WRONG. BBC does NOT postulate that matter is expanding from a small, dense blob into empty space; rather, it describes a Universe in which SPACE ITSELF is growing at a (more or less) steady rate. Matter density is not decreasing in the way that ink density decreases as it expands into a large container of liquid; rather, the density of matter is decreasing because space is expanding as the amount of matter remains the same. Also, space is not expanding into anything, like an exploded material expands into the space around it. Space is just expanding, period. It is difficult to visualize, but the math works out just fine.
Why does the water become less dense when it expands?
Because the same amount of matter now occupies a larger space, therefore decreasing its density.
How fast does a black hole take parts of space away?
Honestly, space doesn't need a black hole to take space away. Everytime a sun/star dies, dark matter expands. Therefore space is taken away anyways.
