How much space would 1 kg of air occupy?

Answer 1

Because a kilogram is a unit of mass and not weight, a one kilogram object on Earth would still be one kilogram on Jupiter. A measure of weight using SI units is the Newton. The gravitational acceleration on earth is 9.8 meters per second squared. We can get the weight of an object on Earth by the equation: Mass X Gravitational Acceleration = Weight (m/g = w) A 1 kg object on Earth would weigh (1 kg) X (9.8 m/s^2) = 9.8 Newtons The gravitational acceleration on Jupiter is 24.79 m/s^2 therefore a 1 kg object would weigh: (1 kg) X (24.79 m/s^2) = 24.79 N

Answer 2

If the 1kg is not influenced by the gravity of a planet or star etc then it would weigh nothing. To have weight, mass must be accelerated to produce a force in newtons (we call this weight). Its weight would change depending on the gravitational influences around it.

Answer 3

1 kg explanation: Your weight on the moon is 1/6th your weight on earth because of a smaller force of gravity. Kg measures your mass and not your weight so therefore 1 kg on the earth is also 1 kg on the moon. This is a commonly confused concept. Since gravity is for all practicality the same all over the planet, people incorrectly use kilograms, which define a mass, to describe their weight. Your weight is equal to the force of gravity on you, which is equal to your mass times the acceleration due to gravity. On the earth the acceleration due to gravity is 6 times greater than the acceleration due to gravity on the moon. Pounds on the other hand is measurement of weight so if you were to take a l pound object to the moon its weight would change to 1/6 th of a pound.

Answer 4

Air can be compressed into a fairly small volume. Also, what gas? What temperature? Some gasses and gas mixes are denser than others.

If you were to release a kilogram of air in the hard vacuum of interstellar space, it would expand for a long time, occupying a tremendously large volume.
At room temperature and atmospheric pressure: V = 0,84 m^3

If you want to get the volume for any temperature or volume:

V = (286.69) x T / V

I got the answer by using p x V = n x R x T

Answer 5

That depends on how far it is from the center of the sun. On the earth or the moon,

that choice is no problem, because they both have solid surfaces to set the scale on.

But the sun has no solid surface, so you have to specify where you're going to do

the weighing.

The TIME/Britannica Almanac 2010 lists the equatorial radius of the sun, and the gravitational

acceleration at that radius from the center. We don't know how that radius is defined with

respect to a ball of hot gas, but seeing it in print is good enough for us.

The 'radius' is 431,853 miles, and the gravitational acceleration there is 275 m/s2.

So, just before your kilogram and your scale both melt and disperse, you get a reading of

275 newtons (61.86 pounds) .

Answer 6

Since the density of air varies, depending on altitude and temperature, let's first assume that we are talking about the density of air as defined by The International Standard Atmosphere (ISA): at sea level, with no water vapour present, and at a temperature of 15 °C, the density of air is equal to about 1.225 kg/m3.

To calculate volume (i.e. the space being occupied), you use the following formula:

volume = mass / density

volume = 1 kg / 1.225 kg/m3

volume = 0.816 m3 (or 1.0677 yd3)
