you can't find the answer out because you don't know how much water is in it to begin with
To calculate the volume of water in a semicircular trough, one should figure out the area of the cross section (the semicircle) first. Then, this number should be multiplied by the length of the trough.
The concentration of oh- ions decreases and thir volume increases . concentration is inversely proportional to volume so as volume increases , concentation decreases and as the volume decreases, concentration increases .
the metonol atoms and water atoms fit togerthe better thn juts methonol or just water so the volume decreases
no, it actually increases
When water at 0 degrees C is heated its volume decreases
Actually it does empty its content until the level of the liquid inside and outside is the same.
The volume of water increase under 3,98 oC.
The effect of temperature on volume is variable, depending on if you are talking about gases or liquids, and within liquids, it is also variable depending on which liquid. So, for gases, as the temperature decreases, the volume will decrease also, as long as the pressure remains constant. For most liquids, as the temperature decreases, the volume also decreases, but with water, as the temperature decreases, the volume increases (ice occupies more volume than does liquid water).
The water is replaced with air which is not as heavy as water for the same volume.
On heating water from O0c to 4oc the volume of water decreases while that of wax increases.
It is an instrument used for water displacement to determine the volume of a gas produced in a reaction.
In general when temperature is decreased the volume decreases and the density increases. This is not true for water around freezingg temperatures, the volume increases and the density decreases and ice floats.
Well boiling decreases its volume, as water vaporises. Secondly, it will kill the germs.
Actually it's not weight we are dealing with here, it is actually density. So what happens is when temperature increases, the density decreases and volume increases or vice versa if the temperature decreases, the density increases and the volume decreases.
It decreases down to 4 deg C and then expands to 0 deg C.
Yes, water expands on freezing to ice. The reverse is true also. When water melts from a solid to a liquid its volume decreases slightly. Note that this property is unusual, and most substances have the opposite volume changes upon freezing/melting.
Density = mass / volume. If the mass decreases, the density decreases.
Its volume increases and its density decreases.
1 litre is a unit of volume, regardless of what it contains, or whether it's empty.
The word 'trough' is a noun, a singular, common, concrete noun; a word for a long shallow container for the drinking water or feed of domestic animals; a pipe, drain, or channel for water; a long and narrow or shallow hollow; a word for a thing.A pronoun is a word that takes the place of a noun in a sentence. The pronoun that takes the place of the noun trough is it. Example:I'll fill the horse's water trough, it looks empty.
The volume increases greatly and the mass decreases somewhat due to the water which is released as steam.
For water the line has a negative slope (vs carbon dioxide). This explains why ice floats since volume decreases with increasing pressure as we move upward on the phase diagram from solid to liquid water, the volume occupied by H20 decreases and thus water must be increasing in density.
If you freeze a given quantity of water, the volume increases. When it melts, the volume decreases. The number of molecules remains the same.
Density is mass per unit volume of a substance. The Mass and volume of water is in the ratio of 1:1 .There fore the density of water is 1. With rise and decrease of temperature the volume increases or decreases to change the water density.
as the bubble rises in the water the pressure decreases (as Pressure = density*acceleration due to gravity*depth in water) which in turn means that the volume of the bubble will increase.
