No. There are three concepts to grasp.
1) Mass. This is the amount of matter in something. Mass stays the same even if you take the thing into space and it becomes weightless.
2) Weight. This is the force exerted on something by gravity. It's what makes it heavy. Standing on the surface of the Earth, it's difficult to understand the difference between mass and weight. Just remember that a 1 kilogram "weight" is still one kilogram even in space where it's weightless or on the moon where it weighs about a third as much.
3) Density. That's mass divided by volume. Copper has the same density whatever shape or size it is. Every cubic centimetre has a mass of just under 9 grams. However, the bigger the lump of copper is, the more mass it has and the more it will weigh.
What else can I help you with?
Is density another word for weight?
No, density and weight are not the same. Density refers to how much mass is in a given volume, while weight is the measure of the force of gravity acting on an object. Density is calculated by dividing an object's mass by its volume, while weight is calculated by multiplying mass and the acceleration due to gravity.
The density of a submerged submarine is about the same as the density of?
The density of a submerged submarine is about the same as the density of the fluid it is submerged in, which is typically seawater. This allows the submarine to float or sink based on its buoyancy and weight.
Is density how much something weighs?
Density is a measure of how compact or concentrated the mass of a substance is within a given volume. It is calculated by dividing the mass of an object by its volume. So while density is related to weight, it is not the same thing.
Is the same amount of sand and water the same weight?
No, sand and water do not weigh the same for the same volume. Water has a density of 1 gram per cubic centimeter, while the density of sand varies but is generally higher, so the weight of the same volume of sand will be greater than that of water.
Does the density of liquid affect it's weight?
Yes, the density of a liquid does affect its weight. Density is a measure of how much mass is contained in a given volume, so a more dense liquid will have greater weight compared to a less dense liquid of the same volume.
Are weight and density the same?
No, weight and density are not the same. They are two different physical properties of substances. Weight is a measure of the force exerted on an object due to gravity, while density is a measure of mass per unit volume.
What is a rubber band's weight?
The weight depends on the volume, or size, and the density of the band. In the same way, a book's weight depends on its volume and density.
Do a pound of cotton and a pound of lead have the same density?
Yes, a pound of cotton and a pound of lead have the same density because density is a property of a material that is independent of its weight. Density is defined as mass per unit volume, so if both the cotton and lead weigh the same, they should have the same density.
When a submarine pumps water out of its flotations tanks its density decreases and it float. Why does its density decrease?
Density is weight divided by volume. Since the size of the hull stays the same, when the weight of the water is removed, the volume of the hull stays the same and the density is reduced.
What will be the density of a lead weight is carried from sea level to the top of high mountain?
The density of the lead weight will remain the same regardless of the change in altitude. Density is a property of the material itself and does not change with elevation.
What metal has the same density as a fishing weight that has a density of 11.3 grams per mililiter?
Lead
Does density of an object depend on the gravity of the object?
Density is not affected by gravity. Density is affected by mass and volume, such that density = mass/volume. Weight, but not mass, is affected by gravity. Weight and mass are not the same thing.
Give the formula for density?
To check density of any liquid , measure liquid & water in same quantity at same temperature & divide liquid weight by weight of water which gives density of liquid at that temperature.Exa. If you want to measure density of alcohol , take it in pre-weighted 10 ml cylinder & weight by using any suitable balance ( like mettller balance) note the reading as A. after that weight 10 ml water in same cylinder after rinsing & measure the weight as reading B. To get the actual weight of liquid & water subtract the empty & dry cylinder's weight-. Now calculated as under-Density of liquid= A-C/ B-C.By- S.Joshi
How is density not mass or weight?
Density is defined as the mass of something divided by the volume of the same thing. During a careful reading of the definition, it becomes apparent that density is not mass, and that density is also similarly not weight as well, either.
Do you find the density of a substance by dividingits volume by its weight?
No. To find the density, you divide the Mass by the Volume.Weight is not involved. Aboard the Space Station, the object has no weight, but it still has the same mass and its density has not changed.
Is density another word for weight?
No, density and weight are not the same. Density refers to how much mass is in a given volume, while weight is the measure of the force of gravity acting on an object. Density is calculated by dividing an object's mass by its volume, while weight is calculated by multiplying mass and the acceleration due to gravity.
