You need to measure the mass using appropriate equipment. You can measure the volume of a textbook and a container of milk by measuring its linear dimensions and calculating the volume.
It is not at all easy to measure the volume of an air balloon. You cannot use displacement of a fluid (water) because when submerged, the balloon would be experiencing water pressure and so would occupy a smaller volume. You cannot measure it by allowing the air to escape and measure that volume of air because that air will no longer be experiencing the pressure exerted by the material (rubber?) of the balloon. I have no answer to this part.
Once you have the mass and volume, the density is merely mass/volume.

density = mass/volume Determine the volume of the screw by using the water displacement method (see related link below). Determine the mass of the screw on a balance or scale. Divide the mass by the volume, and that will be the density.
0.75 kg/L
The same way you determine the density of any other object. Divide the mass by the volume. Add: density = mass/volume = 5g/1mL = 5g/mL = 5g/cm3* *1mL = 1 cm3
Yes, the density of an object has no relation the number of pieces that the object is divided into, nor to the size of the obect. For example: The density of 1 pound of steel is exactly the same as the density of 1 ton of identical steel, and the density of 1 mL of water is exactly the same as the density of one Liter of water. That is the textbook answer, in real life most cutting techniques disturb the boundary of the cut line. So if you want a real to life answer then the density is only changed at the cut line where temperature and pressure will effect the structure of the metal being cut. Textbook answer is density remains unchanged throughout the whole of the material no matter how many times you cut it. think of density as "how hard something is packed together at the molecular level". This is a ok way to look at density. Cheers!
To determine the density of each 50 mL liquid container, you would first weigh the empty container. Next, fill the container with the liquid and weigh it again. The difference in weight between the filled and empty container can be used to calculate the density by dividing the weight of the liquid by the volume of the container.
You can lower the density of hydrogen (or any) gas by heating it in a container where it is free to expand, like a balloon.
Density of any balloon depends on the material of the balloon and how much the balloon is filled.
To determine the mass of water inside the container, you would need to know the volume of the water and its density. The mass can be calculated using the formula: mass = volume x density.
Water displacement method will work fine with molecules that do not dissolve... Here you have something that will dissolve in water, changing it's density. What I would do is to weight a graduated container, put some sugar (more you add, more precise will be the result) in the container... Better weight the container before... Weight the container after. Now you know the *weight* part of the answer, then you melt it, in that container... you read the *volume* part of the answer. put the part together to have a density which is mass/volume g/cm³ for example, or g/mL, which is the same.
because as you heat the gas, you cause the gas to expand on the container (whish is a balloon), this lowers the density, and a less dense fluid submersed in a denser fluid will rise, like an air bubble rises from underwater
Air density can be determined by measuring the mass of a known volume of air and then calculating the density using the formula: density mass/volume. This can be done using instruments such as a balance and a container of known volume.
Density is inversely related to the flight of a hot air balloon. As the density of the air inside the balloon decreases, it becomes less dense than the surrounding air, causing the balloon to rise. This is because the buoyant force on the balloon is greater than its weight.
You can determine the density of a liquid by measuring its mass and volume, then calculating the density using the formula density = mass/volume. The liquid with the highest density will sink to the bottom when layered with other liquids of different densities in a container.
The density of the material is greater than the density of water if it sinks to the bottom of the container when placed in water.
The density of the material is greater than the density of water because it sinks to the bottom of the container. Objects with a density greater than that of water will sink in water.
The density of a balloon will decrease when the amount of air inside it decreases, causing it to become less dense compared to its surrounding environment. This decrease in density may happen if air leaks out of the balloon or if the balloon is subjected to a higher altitude where the air pressure is lower.
