What else can I help you with?
What will happen when cold air and warm are added to the same container?
when cold and warm air are added in the same container it causes water.
A student weighs a container and then adds air When the student weighs the container again the weight will be?
Greater than before, since the added air increases the total weight of the container.
If two things weigh the same in water do they weigh the same in air too?
they would weigh the same everywhere
Is the volume of air inside a container still the same when some water is poured inside?
No, the water displaces the air if the container is open.
How can additional gases can be added to the air?
Additional gases can be added to the air by releasing them from their current container or confinement. Gases will naturally mix together in various concentrations depending on their composition.
What weighs less a pound of cold air or a pound of warm air?
They weigh the same. Both are defined in your question as a pound.
Will a lorry with birds on it weigh the same if all the birds lift up in the air?
If the lorry contains the birds in a sealed container then the weight is unchanged. As they lift from their perches they must accelerate and the resultant downward force on the lorry will make it appear to weigh more for a very short time.
There are 10 grams of iron in a sealed container with moist air The sealed container with iron and moist air weighs a total 15 grams what is true after the iron rusts?
After the iron rusts, it will combine with oxygen from the air to form iron oxide. Since the total weight of the sealed container after the iron rusts is still 15 grams, the added weight will be the mass of the oxygen atoms that combined with the iron to form iron oxide.
What weighs more a flat or full tire?
A full tire is heavier than a flat tire. When a they are both flat they weigh the same but added air makes the full tire heavier.
How will you provide that the air has weight?
Take a large container, pump out all the air from inside it. Weigh it. Put air inside and then weigh it again. The difference would be the weight of the air inside. Air molecules have mass (air is "stuff") and things with mass have weight when in a gravitational field, such as on Earth. If air didn't have any weight, we wouldn't even have an atmosphere.
How many tons of cornmeal can be packed into 40 ft container?
Of what? One full of air will weigh a lot less than one full of steel. In practice, they have safe weight limits. A metric ton of air, weighs the same as a metric ton of steel! Its still a ton! A container can carry approximately 28 metric tons, varies slightly between companies, and then depends on loading/unloading facilities.
When a ruler is placed into a clear container what changes take place?
-- Some of the air in the container is forced out, being displaced by the volume of the ruler, and being unable to occupy that same space at the same time. If there is liquid in the container, then the same goes for the liquid. -- If there is liquid in the container, then at least part of the ruler becomes wet.
