Both the mass and weight remain unchanged. However; generally; the volume increases due to the thermal expansion of the substance when heated up.
They are different in non-homogeneous mixtures. Here's an example. If you put a few drops of water in a balloon, the contents are 99.9% (or so) water by weight and 99.9% (or so) air by volume.
Density can be calculated from molecular weight using the formula density = (molecular weight) / (molar volume). Molar volume is the volume occupied by one mole of the substance and can be calculated using the ideal gas law or experimental data. Dividing the molecular weight by the molar volume gives the density of the substance.
A cubic meter is a unit of volume, not weight. You would also need to know the density of the substance. For example 0.0175 cubic meters of water will weigh much more than the same volume of air.
The weight of 50ml will depend on the density of the substance you are measuring. To calculate the weight, multiply the volume (50ml) by the density of the substance in grams per milliliter (g/ml).
The weight of 40ml of a substance depends on its density. To find out the weight in grams, you would need to know the density of the substance in question. Different substances have different densities, which will affect the conversion from volume (ml) to weight (grams).
This depends on the substance. Re-ask the question with the substance or density of the substance. Gallons -> volume Lbs -> weight Weight = volume X density
Density measures how compact a particular substance is. It can be calculated by adding the weight with the volume of the substance. To figure out the density of sugar you must first know the weight and volume and then plug them into the equation: density = weight + volume.
The density is measured by dividing the mass of the substance with it's volume. Density = Mass/Volume.
weight is different in different gavities but mass is not, volume is not involved
They are different in non-homogeneous mixtures. Here's an example. If you put a few drops of water in a balloon, the contents are 99.9% (or so) water by weight and 99.9% (or so) air by volume.
Specific gravity.
Density can be calculated from molecular weight using the formula density = (molecular weight) / (molar volume). Molar volume is the volume occupied by one mole of the substance and can be calculated using the ideal gas law or experimental data. Dividing the molecular weight by the molar volume gives the density of the substance.
It completely depends on whether or not there is any substance in the volume, and whether the volume is anywhere near a planet.
Hmmm... technically false. Density is mass/volume - it is an intrinsic property. Weight is subjective to the force of gravity, while density is not.
This depends on the density of the substance. Liters: Volume Tonne: Weight Density = Weight / Volume Volume = Weight / Density
It does not. It equals volume. The weight will vary depending on the substance occupying that volume.
