It is the easiest way to affect the volume which would change the density. However, if you increase the pressure but keep temperature constant the volume will also change. Any change in volume affects density.
This is an unusual question. Nothing qualitative really happens upon its increase in density and this is quite a difficult thing to do: mere fluctuations in temperature and pressure (even immense changes) can shift water's density by as much as only 3%. Water is most dense between 4 and 5 degrees celsius. There is a drop in density below this (even when supercooling the water).
Depends on the type of beer. Alcohol content affects the liquid density which affects the weight in a given volume. A 12oz can of Miller High Life weighs 360 grams. I only know that because I happen to be drinking one right now, and I have a scale next to me.
Air Temperature, because the surface of the water is the only thing that needs to be heated so the warmer the air temperature, the faster the air can heat the surface of the water the faster evaporation will be able to occur,
The density of something is the mass divided by the volume, so if you cut the item in half, it will not change the density at all. Instead, the two halves of the item will have the same density.
The density of an object is constant, therefore, no rock can have less density in water.
Salinity, or saltiness, affects how readily the water changes temperatures as well as its density. Because of this, currents in the water can arise not only from the difference in temperature, but also from the density difference, which comes from the salinity itself.
The density depends on temperature.
The density of cutted pieces is identical; of course this is valid only for a homogeneous material.
In most substances, maximum density occurs at the lowest temperature attainable. The only substance that this is not true for is water, whose maximum density is at 3.98 degrees Celsius.
Enzyme activity increases with temperature, but only up to a point.
In the case of gases yes. For a gas, the density is directly proportional to the pressure and inversely proportional to the temperature (absolute ie Kelvin). In other words the higher the temperature the lower the density. This is because gases expand with temperature. Liquids and solids do expand but only slightly so there is not much change in density for these.
No Density also drives convection.
air density and temperature
Different from what? If you mean different from the surroundings, the density depends not only on temperature; but also, and MAINLY, on the type of materials. For example, water has a density of about 1 kg/liter, regardless of the temperature. There is some minor variation as a function of temperature, but it is fairly small. Gold, on the other hand, has a density of about 19 kg/liter; once again, this doesn't depend a lot on the temperature.
no it effects another thing like reading one and paying attention
The density of water is only 1 g/cm3 at 4 degrees Celsius. Any other temperature, and the density is less than 1. So technically, if it was not 4 degrees, you would change its temperature to increase its density. The only other way to increase the density is to add things to/dissolve things in the water, such as salt, sugar, or anything else soluble in water.
No the only thing that affects them is antibiotics.
