What has a greater density 0.8 or 0.7?
The answer depends on what the numbers measure. If they are the masses of equal volumes of substances, then the substance with mass 0.8 is denser. On the other hand, if the numbers refer to the volumes of equal masses of two substances, then the substance with volume 0.7 is denser.
What would a graph about masses and volumes represent?
A graph about masses and volumes would represent density.
Why can mass be used to distinguish between equal volumes of two substances?
Mass can be used to distinguish between equal volumes of two substances because mass is a measure of the amount of matter in an object, while volume measures the space it occupies. Different substances have different densities, which is the ratio of mass to volume. Therefore, if two substances have the same volume but different masses, their densities will differ, allowing for distinction. This property is particularly useful in identifying substances and determining their purity.
What properties of solids determine the volumes and surface area?
Resistance to deformation.
What is the equation for finding temperature when mixing equal volumes of water?
The result of mixing equal MASSES of water at different temperatures will be the mean of the two temperatures. Unless you are being very sophisticated and are taking the thermal expansion into account, the same will apply to volumes.
What has a greater density 0.8 or 0.7?
The answer depends on what the numbers measure. If they are the masses of equal volumes of substances, then the substance with mass 0.8 is denser. On the other hand, if the numbers refer to the volumes of equal masses of two substances, then the substance with volume 0.7 is denser.
Equal volumes always mean equal masses?
Not necessarily. Equal volumes do not always mean equal masses because different substances have different densities. Denser substances will have more mass in a given volume compared to less dense substances.
What would a graph about masses and volumes represent?
A graph about masses and volumes would represent density.
When equal masses and volume of two substances are mixed find the density of each substance?
Take two hypothetically substances A and Bin equal masses (eg. 1 kg A and 1 kg B) and taken in equal volumes ( 0.8 L A, and 0.8 L B), then they already have the same density (both are 1.25 kg/L A and 1.25 kg/L B) each other apart. (that's how the question was formulated)HOWEVER:when mixed together the masses add up (Mass conservation law) to 2 kg A+B,BUT total volume is not exactly added up (no conservation law for volume). Normally some contraction takes place, then Vtotal < 1.6 L (sometimes more than 2% contraction)
When you compare masses of the same volume of different substances you are doing what?
You are comparing their densities. Density is a measure of how much mass is present in a given volume. By comparing the masses of the same volume of different substances, you can determine which substance is more or less dense than the others.
Is density the volume of equal masses of substances?
yes
If two solids have the same masses and different volumes do they have different or equal densities?
different equal
If you know the molar masses of the reactants in a chemical reaction can you determine the molar masses of the products?
If you know know the molar masses of the reactants in a chemical reaction you can determine the molar masses of the products because the combined molar masses of the reactants equals the combined molar masses of the products.
Can two different substances with the same volume have similar masses?
Take three identical bottles. Fill one with air, one with water, and one with stones. The volumes of all three bottles are the same, but their weights are different, because they contain different masses. Different substances can easily have different masses in the same volume. That's why the concept of "density" is so useful.
How do you know which one of two mediums is denser?
You can determine which medium is denser by comparing their densities - the medium with the higher density is denser. This can be done by measuring their masses and volumes, or by observing which one displaces more fluid in a graduated cylinder when placed in it.
Do objects of the same size and shape have the same mass?
Not necessarily. Mass is a measure of the amount of matter in an object, so two objects of the same size and shape can have different masses if they are made of different materials or have different densities.
Is 1g of food equal to 1g of gold metal?
The masses are equal.The volumes are different.The values are different.
