If you double the volume of a sample ... scoop up twice as much of it ...
the mass of the sample always doubles. But the density of the substance
doesn't change.
Think about it: The density of some water out of my dog's water bowl is
the same as the density of some water out of Lake Michigan.
You will like to know the volume of the mass. Mass / volume will give you density. You can not know the density without mass and volume of the substance.
No, density changes when both mass and volume increase. Density is calculated by dividing mass by volume, so if both mass and volume increase proportionally, the density will remain the same. If mass increases more than volume, or volume decreases more than mass, density will increase.
To calculate density, you need both the mass and volume of an object. If only the mass is given (220g), you would need the volume of the object to calculate its density. Density is equal to mass divided by volume (density = mass/volume). So without the volume of the object, the density cannot be determined.
No, density is not directly proportional to volume. Density is defined as mass per unit volume, so it is determined by both mass and volume. Two objects with the same volume can have different densities if they have different masses.
The density of the rock is calculated by dividing its mass (56 grams) by its volume. If the volume is unknown, then the density cannot be determined. Density is the mass per unit volume of a substance, so both mass and volume need to be known to calculate it.
The volume is doubled.
No. Volume and density are both measures - of different characteristics.
Density = Mass/Volume. As a result, density is entirely dependent on both mass and volume.
Density is determined by the mass of a substance divided by its volume. Therefore, both mass and volume do affect the density of a substance. If the mass increases without a corresponding increase in volume, the density will increase. Conversely, if the volume increases without a corresponding increase in mass, the density will decrease.
Density = Mass/Volume. You cannot calculate density without knowing BOTH mass and volume.
If the radius and height of a cylinder are both doubled, then its surface area becomes 4 times what it was originally, and its volume becomes 8 times as much.
You will like to know the volume of the mass. Mass / volume will give you density. You can not know the density without mass and volume of the substance.
Density is by definition mass divided by volume. Therefore volume times density equals mass. Diving both sides of that equation by the density, we get volume equals mass divided by density. So the answer to your question is, divide the mass by the density.
No, density changes when both mass and volume increase. Density is calculated by dividing mass by volume, so if both mass and volume increase proportionally, the density will remain the same. If mass increases more than volume, or volume decreases more than mass, density will increase.
If the volume is doubled and the number of molecules is doubled while the temperature is held constant, the pressure of the gas sample will remain the same. This is because both the volume and the number of molecules increased by the same factor, resulting in no net change in pressure according to the ideal gas law.
