Capacity is technically the measure of how much an object can hold. For example, a container, a cup, a dam, etc. This is generally measured in liters. Volume is technically the measure of how much space a (solid) object takes up. For example, a ball, a rock, a boat. This is generally measured in m³. … Read more

TMC is an abbreviation of "thousand million cubic feet" - a measure used for very large water bodies such as dams and lakes. However, it is also used as a product name for water tanks. In this case, the volume measure can be easily calculated if the tank is cylindirical, using Volume = Pi * … Read more

A Cup is a measurement of capacity or volume, whereas a gram is a measure of mass (~weight). Therefore, technically they can not be compared. However, for water 280 g = 280 cm³ = 280 ml. One (metric) cup = 250 ml. Therefore 280 grams of water = 1.12 cups.

Uranus's atmosphere, while similar to Jupiter and Saturn's in its primary composition of hydrogen and helium, contains more "ices" such as water, ammonia and methane, along with traces of hydrocarbons.   It is the coldest planetary atmosphere in the Solar System, with a minimum temperature of 49 K (–224 °C). It has a complex, layered cloud … Read more

I suspect that the wording of this question is not quite technically correct.  I am assuming that the person asking this question is enquiring about the unit of measurement ('mesh') that is used for measuring the sizes of beads and meshes (eg wire meshes).  If this is the case, within the United States, the mesh … Read more

An equal mass of sugar crystals. This is because the rate of a reaction wil be faster when the surface area of reactants is larger. In this case, the separate crystals have a much much larger combined surface area.
