If air bubble were trapped in your solid beneath the liquid level in your density determination what error would result in the volume measurement?
An air bubble in the solution would effectively increase the volume that you measure for the solid because you would coutn the volume of the bubble as the volume of the solid (but of course, it's just air!).So if you measure the density of a solid by putting a weighed amount of the solid in a liquid (in which the solid is insoluble), then an air bubble in the solution would make the measured volume of the solid larger than it really is.Density is found by taking the mass divided by volume. Assuming you find the mass correctly, if the measured volume is larger than the real volume, the denominator in the fraction (mass/volume) will be too big. If a denominator is too big, than the fraction is smaller.Therefore an air bubble will cause you tounder estimate the density.
Why is it unlikely for the volume of air to reach zero?
There would literally be no air as there would be no space for it to occupy. If you compress air sufficiently it will liquify, but stilll occupy a discrete volumes.
How many cups is equal to a quarter pint of milk?
There are 2 cups in a pint, so a quarter pint would be 1/2 cup
What happens to the volume of air in the syringe?
A syringe is similar to a balloon in effect on pressure. The more air you insert, the less space for fluid. The more pressure exerted on it, the less volume of air and the more the liquid would fill up the space.
If air is 20.9 percent oxygen by volume what is the volume of air that contains 225 ml of oxygen?
Divide 225ml by 20.9, then multiply by 100.
What volume of air is contained in an empty 250ml aluminum can?
Gases are compressible so the actual volume is not possible to determine. Except if it is not compressed at all then it is 250ml.
How would I calculate the mass of air in an empty flask?
From the volume of the flask, and the density of air under the conditions in the room, you can calculate the mass of air. The density of air varies with pressure, temperature, humidity, etc. At sea level and at 15 °C air has a density of approximately 0.001225 g/ml, so under these conditions, a liter flask would contain (1000 ml)(0.001225 g/ml) = 1.225 g of air.
About how many kilograms of air occupy a classroom that has a 200-square meter floor area and a 4-m-high ceiling?
To calculate the volume of the classroom, we multiply the floor area by the height: 200 sq m * 4 m = 800 cubic meters. The density of air is approximately 1.225 kg/m^3 at sea level and room temperature. Therefore, the mass of air in the classroom would be 800 cubic meters * 1.225 kg/m^3 = 980 kg.
What is the amount of mass given volume of air is its?
The mass of a given volume of air depends on its density. Density is defined as mass per unit volume. To calculate the mass of a volume of air, you would need to multiply the density of air by the volume of air you are considering.
What volume of air has a mass of 100g?
The volume of air with a mass of 100g would depend on the density of the air. The density of air at room temperature and pressure is approximately 1.2 kg/m^3. Using the formula density = mass/volume, you can calculate that the volume of 100g of air would be approximately 0.083 m^3.
What is a simile of an empty classroom?
An empty classroom is like a blank canvas, waiting for students to fill it with colors of knowledge and creativity. It's a quiet garden, ready to bloom with the laughter and learning of curious minds. Just imagine the possibilities that can blossom in that empty space, like a field of wildflowers on a sunny day.
How do you measure the density of an empty school bag?
To measure the density of the empty school bag including the air in the bag, you should be able to simply weigh it, and measure its dimensions, and calculate the density, which is weight divided by volume. Bags have a more or less rectangular shape, so the volume is simply length times width times height. If you want to measure the density of the material from which the bad is made, that is a little more complicated, and might require you to squeeze the bag into some kind of compact, easily measured shape, that does not contain air.
Why don't empty plastic juice containers get crushed at sea level air pressure?
Because even though it looks empty. There's still air inside, the air inside is of the same pressure as the air outside the container. Now of you were yo actually have the plastic container be actually empty, with nothing not even air. Then yes. It would be crushed. The vacuum formed would pull the walls inwards and the air pressure outside the container would push inwards.
What is 7 percent volume of air in parts per million?
To convert a percentage to parts per million (ppm) for air volume, you would multiply the percentage by 10,000. Therefore, 7% of air volume would be 70,000 parts per million.
What is the mass in kilograms of the air in a classroom that has a volume of 79.6 cubic meters?
That's going to depend on the density of the air, which in turn depends on thetemperature and atmospheric pressure in the classroom.IF the classroom is at sea-level and the temperature is 59° F, then you've gotyourself a room full of ISA Standard Atmosphere right there, and the mass of theair in the room is (79.6 x 1.275) = 101.49 kilograms.At least it would be, if there were no students, teachers, or furniture in the room.
A volume of air has a temperature of 0C. an equal volume of air that is twice as hot has a temperature of?
The equal volume of air that is twice as hot would have a temperature of 20C. Temperature is directly proportional to the average kinetic energy of the air molecules, so doubling the temperature would double the kinetic energy of the molecules.
Why does an empty sealed bottle collapse with altitude?
Actually, an empty sealed bottle should expand slightly as altitude increases. At the altitude where the bottle is sealed, the air pressure outside the bottle is equal to the air pressure inside the bottle. When the bottle is transported to a higher altitude, the air pressure inside the bottle is greater than the air pressure outside the bottle (In other words: There are more air molecules per unit volume inside the bottle than outside). The increased air pressure inside the bottle relative to the outside pressure causes the bottle to expand slightly. An empty bottle would not collapse as altitude increases.
