Most substances contract and decrease in volume when they get colder because the decrease in temperature causes the particles to move slower and closer together. This is due to the decrease in thermal energy, resulting in a decrease in the average kinetic energy of the particles.

What happens to the volume of most substances as they are heated?
Most substances expand as they are heated because the increase in temperature causes the individual particles to move faster and spread out, resulting in an overall increase in volume. This expansion is due to the increased kinetic energy of the particles.
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?
Most substances expand when they are heated, causing the atoms or molecules to move further apart. The increase in volume with temperature leads to a decrease in density because the mass remains the same while the volume increases.
What increases with heat and decreases with cold?
Volume of most substances increases with heat and decreases with cold.
What happen to volume of substance when placed say in a freezer?
When a substance is placed in a freezer, it usually contracts and decreases in volume. This is because the colder temperature causes the particles in the substance to slow down and come closer together, resulting in a decrease in the overall volume of the substance.
What happens to the volume of most substances when they get hot?
It expands

How mercury functions in a thermometer?
Mercury, like most substances, expands when it gets hotter and contracts when it gets colder. A mercury thermometer is designed so that the volume of the mercury can be accurately observed, as the mercury rises or falls in a marked column.
How does solidification affect an objects volume?
The volume of most substances will reduce if the substance changes from liquid to solid.
Do solids change volume?
Most solids expand as they increase in temperature and contract as they get colder. Interestingly, water after it freezes will start to expand as it gets even colder.
What happens when most substances are heated?
All get very hot.
What happens as most substances are cooled?
Sometimes they get cold or start to freeze.
What happens to An organism if its cell membrane became permeable to most substances?
It would die as harmful substances enteres the cells.
What increases with heat and decreases with cold?
Volume of most substances increases with heat and decreases with cold.
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.
