Properties of molecule Flashcards
is the measure of how much solute can dissolve in a solvent at a given temperature and pressure, resulting in a uniform solution. It varies for different solutes and solvents; for example, sugar dissolves well in water, while oil does not.
SOLUBILITY
is influenced by factors such as temperature, pressure, and the chemical nature of the substances involved.
Solubility
is the substance that gets dissolved in a solution. It is usually present in a smaller amount compared to the solvent.
solute
is the substance that dissolves the solute to form a solution. It is usually present in a larger amount compared to the solute.
solvent
Temperature at which the substances changes from solid to liquid under standard atmospheric pressure. At this specific temperature, the molecules in the solid gain enough energy to overcome intermolecular forces, allowing them to move freely and transition into the liquid phase. The melting point varies for different substances and is influenced by factors like pressure and molecular structure
MELTING POINT
is the temperature at which a liquid transitions to a gas at a given atmospheric pressure. At this temperature, the vapor pressure of the liquid equals the surrounding pressure, allowing bubbles of vapor to form within the liquid. The boiling point varies for different substances and is influenced by factors such as atmospheric pressure and impurities.
BOILING POINT
the tendency of a liquid to acquire the least possible surface area, allowing small objects to float on it.
SURFACE TENSION
is like a skin on top of the liquid, holding its shape and creating a surface that allows for small insects and light objects to float in it. It’s because the water molecules are sticking together tightly.
SURFACE TENSION
It is the measure of a liquid’s resistance to flow. It describes how thick or sticky a liquid is; for example, honey has a higher viscosity than water because it flows more slowly. Viscosity is influenced by factors such as temperature and the molecular structure of the liquid.
VISCOSITY
is the pressure exerted by the vapor (gas) of a liquid when it is in equilibrium with its liquid phase in a closed container. This means that some molecules of the liquid escape into the gas phase, while others return to the liquid phase.
VAPOR PRESSURE
pressure means that a significant number of molecules have enough energy to escape from the liquid phase into the gas phase. This typically occurs at higher temperatures or in substances with weaker intermolecular forces, allowing more molecules to break free and become vapor.
