When a substance cools, its particles lose energy and move closer together, leading to a decrease in volume. This is because the decrease in temperature causes the particles to move more slowly and occupy less space.
If the volume is tripled, the mass will stay the same as long as the substance remains constant. Mass is an intrinsic property of matter and is not affected by the volume it occupies. The density of the substance will decrease as the volume increases.
When you keep the volume constant and increase the mass of a substance, the density of the substance will also increase. Density is calculated as mass divided by volume, so if volume stays the same and mass increases, density will increase as well.
When a substance undergoes thermal expansion, its particles gain energy and move farther apart, causing the substance to increase in volume. This increase in volume is due to the increased average kinetic energy of the particles, leading to the substance taking up more space.
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.
The density of a substance remains constant regardless of the amount of the substance. Density is an intrinsic property of a material and is determined by its mass and volume. Increasing the amount of substance will only change the mass and volume proportionally, thus keeping the density constant.
When a substance cools down, it contracts or shrinks in volume. This is due to the decrease in kinetic energy of the particles, causing them to move closer together and reducing the overall volume of the substance.
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
the solids de-reacts with the aqueos substance
As something cools down, the kinetic energy of its molecules decrease. This corresponds to a decrease in volume occupied of the substance, so the density decreases.
When a molten substance cools and solidifies, its particles slow down and come together to form a solid structure with a fixed shape and volume. This process involves the removal of heat energy, leading to the formation of a regular and ordered arrangement of atoms or molecules in the solid state.
Nothing happens if the volume is also allowed to increase.
If the volume is tripled, the mass will stay the same as long as the substance remains constant. Mass is an intrinsic property of matter and is not affected by the volume it occupies. The density of the substance will decrease as the volume increases.
When you keep the volume constant and increase the mass of a substance, the density of the substance will also increase. Density is calculated as mass divided by volume, so if volume stays the same and mass increases, density will increase as well.

This type of property can be obsevered without destroying the substance
An increase in volume that occurs when heat is added to a substance is called thermal expansion. This happens because the particles within the substance gain kinetic energy and move further apart, causing the substance to expand.
Use particle theory of matter to describe what happens to the density of a substance when it cools down
