This question requires density to answer. Density is a ratio of mass to volume, and is dependent on temperature. Materials do have variable density based on temperature. The equation for density is mass/volume.
The capacity (or volume) of a cylinder is pi*r2*h where r is the radius of the base and h is the height. Use this equation to find r and then double it to get the diameter.
Thirty gallons of anything is thirty gallons. Maybe you're asking about compressing helium, but you need to say what pressure you're using and what temperature, to determine how much helium will fit into a 30 gallon tank.
Multiply them: density*volume = mass
Use the volume fomula L*W*H
width = volume/(length*height)
Capacity is the same as the volume of the inside of a container. Often, in mathematical exercises, the internal and external volumes are assumed to be the same (ie thickness of the container is zero). In this case, the capacity is the same as the internal or external volume.
As the volume of a given gas sample is dependent on its temperature and pressure; to find a volume of any gas which does exist, the temperature and the pressure of the system/vessel should be given directly or could be calculated.
The capacity (or volume) of a cylinder is pi*r2*h where r is the radius of the base and h is the height. Use this equation to find r and then double it to get the diameter.
You can find the mass of a substance dissolved in a solution given temperature and joules using the relation q=mc(change in T). Where q is heat in joules, m is the mass, c is the specific heat capacity, and T is the temperature.
capacity
Capacity generally implies volume in geometry. To calculate the volume of a triangular prism, find the area of one of its triangular bases and multiply it by the height of the shape.
Charles found that when the temperature of a gas is increased at constant pressure, its volume increases. When the temperature of a gas is decreased at constant pressure, its volume decreases.
Volume = pi*r2*h
Thirty gallons of anything is thirty gallons. Maybe you're asking about compressing helium, but you need to say what pressure you're using and what temperature, to determine how much helium will fit into a 30 gallon tank.
Volume = mass / density
It is necessary to measure the volume with an adequate device or geometrically.
By comparing the volume given to each figure.
