Expansion means that the volume increases......
It won't change. Density is volume divided by mass, so if volume doesn't change, density doesn't change unless you change the mass of the object.
it changes
A [multiplicative] change in one dimension makes the same change in the volume. So the volume would be tripled.
Yes, a change of state can affect an object's volume. For example, when a substance changes from a solid to a liquid or a gas, its volume can increase. This change in volume is due to the different arrangements of particles in each state.
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.
yes volume has a defined shape and volume gas does not have a definite shape or volume liquid does not have defined shape but does have define volume
With constant mass, a decrease in volume will increase the the density. Conversely, an increase in volume will decrease the density.
thermal expansion
Density = mass / volume. Therefore, if volume increases and mass doesn't change, density will obviously decrease.
She realizes that objects have specific names.
must decrease
Volume is extensive because it depends on the amount there is unlike an intensive property such as density because and objects density will never change no matter how much there is of it.
