How does the volume and density of a substance change when it is heated?
The volume of a substance increases when heated, causing a decrease in density.
A heated metal block volume decreases or increases?
It decreases
When water at zero degree Celsius is heated its volume?
Its volume decreases from 0° to 4°, and then increases from 4° to 10°.
What happened with density of gases on heating?
As gases are heated up, its volume increases, resulting in a decrease of density.
Would the gap in a metal ring increase as it is heated?
Increases If the gap can easily be conceived as a small break in a metal ring, then the expansion of the metal ring may decrease the gap size.
When volume is increased does pressure increase or decrease?
Neither. Volume is independent of mass. Effectively, if you increase the volume of a substance you are moving the particles that comprise that substance apart. Eventually, you would have a gas which expands to fill the volume of its container.
What happens to the density of a heated iron block?
The density will decrease because the heated metal contracts and its particles slow down.
Does the volume of an object change if heated?
The volume of a substance increases when heated
Why do gases expand on heating?
When particles are heated up they gain energy. This causes them to move more and spread out. This causes the volume to increase and the density to decrease.
Why does the mass of magnesium sulfate decrease when heated?
It does not decrease in mass, only weight, the mass is still all there, but as when it has been heated smoke is given off from the element, and goes into the atmosphere. It may not sound like the mass is all there with the heated element, but if the smoke were conserved during the experiment the weight would be the same as before the experiment.
When fluids expand when they are heated does their density increase?
No. Remember that density is a ratio of mass compared to volume. If the volume increases without adding more mass, then the density would decrease. This is why hot air balloons rise.
What is convection central heating?
Convection is a way to transfer heat. When something is heated, by flame, for example, the air right above the flame will expand [as substances expand when heated]. This expansion will cause it to have a greater volume. The air will have the same mass, so its density will decrease as density is mass over volume. Because its density decreases, it will rise. Once risen, it will do the opposite: lose the energy by cooling, decrease in volume, increasing the density, and fall back down.
