on a cold wintry morning, the tires of a car appear flat. how has their volume changed overnight?

Molecules are slowed down when it is cold therefore they contract and therefore the tire looks low. When its heated back up it will return to prior state

Make a comment about the weather or the traffic...\n"boy, was it cold this morning, did not feel like going to work..gee ! so many cars..How do you come here ?..\n\nSmall things and ask for their opinions so they answer you..\n\nAnd how are you this morning ??:-)

No. It would have to be extremely cold before one would crack. I've had them in my vehicle when it got down to -10F and nothing happened.

15a) Ahh, lengths, areas, and volumes. Lengths are proportional to each other, areas are proportionatl to the square of the length, and volumes are proportional to the cube of the length.\n\na) The ratio of the area of the windscreen is ⅜^2\nb) The ratio of the capacities of their boots is ⅜^3\nc) The ratio of the widths is ⅜\nd) I suppose the model car has four wheels, just the original. It's a model, after all.\n\n15b) we are looking for a rectangle with area equal to 16. Let the width be w. Then the length is w + 6.\n\n16 = w(w + 6)\nw^2 + 6w -16 = 0\n(w + 8)(w - 2) = 0\n\nw = 2, and the length is 8. The area is 16.

clincher's are standard type that most folks are familiar with.\n\ntubulars you have to glue to the rim (special type of rim) tube is sewn up inside the tire casing, making flats very hard to repair.

An example of this is when the air is released from a pneumatic tire; the outlet air will be noticably cooler than the tire, and after all the air has escaped the valve stem will be cold to the touch. Diesel engines rely on adiabatic heating during their compression stroke to reach the high temperatures needed to ignite the fuel. Such temperature changes can be quantified using the ideal gas law.

Due to the force of gravity which exert a pressure on all objects towards the center of the earth.This force makes pressure on the entire car which in turn transfers the force onto the tyres.Hence the tyres are always flat at the bottom.\n\nFor more information you can make a search on Sir Issac Newton's Law of gravity.

Well take that skinny tire and put the normal tire pressure on it and see what happons. It will come off the rim.\nThe best way to explain this is look at the so called donut spair tire that you find on your car. It has 60psi in in and you put all that waight of the car on it.\nSame thing with the bike tire. It has a lot of waight on it for such a small tire, thus the hight psi.

I am making the assumption that the balloon is inflated with helium.  The molecules of helium contract when they are cold and expand when they are hot.  So if you put the balloon in the refrigerator or outside on a winter day, it will become smaller.  Once you put the balloon back into a warm environment, it will expand back to it's original size.

That's just the nature of the optics. They need to be bent in order to have you - from the front seat - see a wide enough area along the side of the car. The result is a curved lenses and distortion.

Put cat litter under the tires or pieces of cardboard, that might help the car get the traction it needs.  Good Luck!

u might have something in your car drawing extar power which is making them dim, or the lens that covers the headlights might be yellowed from the sun.

When the tyre goes over ice it actually adds heat to the ice due to friction of the tyres on the road. Therefore when you are moving over -1 degree celcius road then you actually heat the ice into water. Because it is water you will not actually be on a solid surface and will move more freely.\n\nAt -10 degree celcius the car friction may not melt the ice very well and so the surface becomes more solid. Because it is  more solid then your friction is better and you are less likely to slip... however dont brake or accelerate quickly or the friction temperature will increase and you get similar reaction to above.

First jack up the car. Put the jack under the car frame. Wind the handle to raise the jack which raises the car which raises the flat tire off the ground so you can take it off.\n\nSecond take off the tire. If you have a wheel cover, take it off first. Get the tire iron, fit it to a lugnut. Loosen the lug nut by winding the tire iron counter clockwise. Take all te lug nuts off. Then take the tire off the wheel.\n\nThird put on the spare tire. Put the spare tire on the wheel. Make sure your spare tire is properly inflated (you should check this periodically in case one day you need to use the spare tire). Then install the lugnuts. Put on a lug nut, wind the tire iron clockwise to tighten the lug nut. Make sure each lugnut is on tight (don't want the tire to wobble on the wheel). But also do not over-tighten which would make it difficult to take the tire off when you replace the tire later. If you have a wheel cover, put it back on now.

As pressure increases, volume decreases.
