What happens to the density of the substance during thermal expansion?
Thermal expansion is the tendency of matter to change in volume in response to change in temperature. During thermal expansion, the density of a substance decreases as its volume increases. Volume is the space occupied by a body. So, when a substance expands on heating, it will occupy more space or will have more volume. But its mass does not change because the amount of matter contained in a body cannot change. Therefore, mass divided by increased volume gives a decreased density.

When you burn logs does mass or volume change?
Mass
How does decreasing the mass change the object's density?
Density is mass divided by volume. If the volume remains the same, decreasing the mass decreases the volume.
Does a fluid's density change when it is compressed and attenuated?
Yes it does change because its mass does not change but its volume does. When it is compressed the density will increase because its volume does. When it is attenuated will decrease because the volume does. Density is mass over volume. Remember: it only works because its mass stays the same and the volume changes.
What experimental method can determine the density of metal?
Density is the mass of the object divided by its volume. By this principle, to determine the density of a metal, place the metal onto a scale to measure its mass. After this, place the metal into a beaker of water and measure the volume change in the beaker. Divide the mass by the volume and you get the density.
What metal has a mass of 35.4 and a volume of 3.11?
A sample of an unknown metal has a mass of 35.4g and a volume of 3.11cm^3. The metal is Lead.
Does the mass of a steel tube increase when it is heated from 30 degrees to 60 degrees?
When steel (or indeed anything) is heated its mass does not change. Volume is altered by cooling and heating. In this case the volume of the steel would increase.
Is metal are matter?
Anything that has mass and volume is matter. Metals have mass and volume, therefore they are matter.
When mass and volume change what happens to the density?
When mass increases and volume stays constant, the density increases. When volume increases and mass stays constant the density decreases. When they both change, then the density will depend on the rate of change of mass and the rate of change of volume.
What is the density of a piece of metal that has a volume of 10cm3 and a mass of 500g?
Volume = mass/volume = 500g/10cm3 = 50g/cm3
How would a synthesis reaction cause the mass of a product to be higher than the metal in a crucible?
Heating a metal in a crucible can cause the metal to react with the surrounding gases. thus, when weighing the metal after heating, the mass increases because of the addition of the gaseous elements
Can a increase in density result from an increase in mass and no change in volume?
Yes. Density is mass/volume so if mass increases so does density if volume does not change
How can you find volume of 10 gram of metal?
Your question isn't specific enough. Depending on the type of metal the mass will be different and the volume will change. Heavier metals will have less volume for those 10 grams, while a lighter metal would require more volume to achieve the same 10 grams.
What happens to the density as the mass and volume change?
it liquifies.
How do you determine the mass of a magnesium metal strip without using a scale?
By a measurement of the mass and volume because: Mass=Volume/Density.
How does density change as the universe expands?
The density of what? Any metal, liquid, etc. will have the same density since density depends on mass and volume of the sample (not volume of the universe).
