What happens when the temperature of a substance decreases significantly A. Most substances will expand. B. Most substances will gain atoms. C. Most substances will contract. D. Most substances will d?
C. Most substances will contract. When the temperature of a substance decreases significantly, its particles lose kinetic energy, causing them to move closer together. This results in a decrease in volume, known as contraction.
Why do the densities of most substances decrease with an increase in temperature?
This happens because the mass of the rod stays the same, but its volume increases. The increase in the volume of matter withincreasing temperature is called expansion. When cooled down, mostmatter decreases in volume and increases in density.
Most substances in temperature and when heat is added to them.?
Most substances increase in temperature when heat is added to them. This is due to the absorption of thermal energy, which causes the particles within the substance to move faster, leading to an increase in temperature.
What will happen if you swirl a mixture of substances with different densities in a centrifuge?
The centrifugal force will cause the denser substances to move towards the bottom of the tube while the lighter ones move towards the top. This separation allows for easy isolation of different components in the mixture.
What is -109 Celsius?
-109 degrees Celsius is a very cold temperature. It is equivalent to -164.2 degrees Fahrenheit. At this temperature, most substances freeze and become very brittle.
How do water's relative densities as a solid and a liquid differ from that of most substances?
you cant.
Why do the densities of most substance decrease with temperature?
Most substances expand as they are heated, causing the atoms or molecules to spread out and the volume to increase. Since the mass remains constant, the density (mass per unit volume) decreases as the volume increases with temperature.
When do most substances lose or gain energy?
Most substances lose or gain energy when their temperature changes.

How does waters relative densities as a solid and a liquid differ from that of most other substances?
Water has a lower density as a solid than it does as a liquid. In the vast majority of substances are denser as solids than as liquids.
Most substances in temperature and when heat is added to them.?
Most substances increase in temperature when heat is added to them. This is due to the absorption of thermal energy, which causes the particles within the substance to move faster, leading to an increase in temperature.
Most substances are?
Most substances are either solids, liquids, or gases at room temperature, depending on their molecular structure and intermolecular forces. The state of a substance can change with temperature and pressure.
How can you separate substances of different densities?
Density Column to Separate Mixtures of SolidsYou could use a density column to separate mixtures of different solids by adding substances that have different densities. Then you would add in the solids, which would land or stop at a substance.
Do different densities cause layering?
In most cases, yes. The more dense compound(s) will sink to the bottom, while the lighter (and for our purposes) less dense ones will stay near the surface. If you're speaking from a geological stand point,(eg. - sedimentary rocks) then no, most of the layering is NOT a product of different densities.
What is the only way the density of a pure substance can change?
The density of a pure substance can change by altering its temperature. As temperature increases, most substances expand and therefore decrease in density, whereas as temperature decreases, most substances contract and increase in density.
How do water's relative densities as a solid and a liquid differ from that od most other substances?
Ice floats. Most other substances are denser in the solid state.
