When a substance is heated, its mass remains constant because mass is a measure of the amount of matter present, which does not change during a physical change like heating. Volume may expand due to thermal expansion, where the particles move farther apart. Weight may appear to change due to differences in gravitational force, but the actual mass remains the same.

What is the difference between percentage by weight and volume?
Percentage by weight refers to the concentration of a substance in a mixture by weight, while percentage by volume refers to the concentration by volume. Percentage by weight is calculated as the weight of the substance divided by the total weight of the mixture multiplied by 100, while percentage by volume is calculated as the volume of the substance divided by the total volume of the mixture multiplied by 100.
How do you calculate density from molecular weight?
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.
What is the equivalent of 0.0175cu.m in weight?
The weight equivalent of 0.0175 cubic meters would depend on the substance being measured. To convert volume to weight, you would need to know the density of the material. You would multiply the volume by the density to get the weight in kilograms or another unit of weight.
How much do 50ml weigh?
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).
How much grams are 40ml?
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).
2000 pounds equals how many gallons?
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
What is sugar's 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.
Is the density of a substance obtained by dividing its volume with its weight?
The density is measured by dividing the mass of the substance with it's volume. Density = Mass/Volume.
Is The weight of a substance is defined as its mass divided by its volume.?
weight is different in different gavities but mass is not, volume is not involved
What is the difference between percentage by weight and volume?
Percentage by weight refers to the concentration of a substance in a mixture by weight, while percentage by volume refers to the concentration by volume. Percentage by weight is calculated as the weight of the substance divided by the total weight of the mixture multiplied by 100, while percentage by volume is calculated as the volume of the substance divided by the total volume of the mixture multiplied by 100.

The ratio of the weight of a substance to the weight of an equal volume of water at 4c is its?
Specific gravity.
Does a volume has a weight?
It completely depends on whether or not there is any substance in the volume, and whether the volume is anywhere near a planet.
True or false Density is the weight per volume of a substance?
False. Density is actually the mass per unit volume of a substance, not weight.
How many cubic liters of bark are in 1 cubic ton?
This depends on the density of the substance. Liters: Volume Tonne: Weight Density = Weight / Volume Volume = Weight / Density
How do you know thickness x length x width equals weight?
It does not. It equals volume. The weight will vary depending on the substance occupying that volume.
What are properties of a substance that will never change?
weight, volume, density, mass
