compounds
Most substances lose or gain energy when their temperature changes.
The substances having the most potential are CFC's. They can be found as coolant in various areas.
No, although it does expand with heat as do most substances.
Ice floats. Most other substances are denser in the solid state.
A table can be used to find the melting point, boiling point, density, and other physical properties of substances. This information is useful for identifying and characterizing different substances.
Most substances lose or gain energy when their temperature changes.
For most substances particles are most packed in the solid state?
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.
Most substances around us are mixtures, rather than pure substances. Mixtures are composed of two or more substances that are physically combined and can be separated by physical means, while pure substances are made up of only one type of particle. Examples of mixtures include air, sea water, and soil.
The substances having the most potential are CFC's. They can be found as coolant in various areas.
true for A+ :)
Elements
At very low temperatures most substances are in solid state.
Most molecular substances do not conduct electricity since the ions don't dissociate very well with molecular substances. However, most ionic substances do conduct electricity very well due to their ability to dissociate very well in water.
The most pure basic substances are elements, which are made up of only one type of atom. Elements like gold, oxygen, and carbon are examples of pure basic substances. They cannot be broken down into simpler substances by chemical means.
