What else can I help you with?
Can you please-Compare the melting points of substances that are gases at room temperature with solids and liquids?
Substances that are gases at room temperature typically have lower melting points than solids and liquids because their intermolecular forces are weaker. Gases have molecules that are further apart, making it easier to overcome these weak forces to change their state. Solids and liquids have stronger intermolecular forces that require more energy to break, resulting in higher melting points.
Why are covalent substances gases and liquid rather than solids?
Covalent substances have weaker intermolecular forces compared to ionic or metallic substances, which makes them more likely to exist as gases or liquids at room temperature. The lower strength of the bonds allows the molecules to move freely and overcome the forces that hold them together as solids.
Are liquids dense?
Some liquids are denser than others. In general, everyday experience, most liquids are denser than gases, but not as dense as solids. There are some exceptions to this rule.
Are both gases and liquids fluids?
yes, gases and liquids are fluids. this term is usually used when referring to resistance since frictio occurs in solids.
Will sugar dissolve in air?
No, sugar will not dissolve in air. Substances dissolve in liquids, such as water, not in gases like air.
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.
Are solids gases and liquids substances?
Yes, all are substances.

Is solubility affected by pressure temperature and type of solvent?
Solubility can be affected by pressure, temperature, and the type of solvent. Generally, increasing pressure increases the solubility of gases in liquids. For solids in liquids, temperature can have a significant impact on solubility - usually, solubility increases with increasing temperature. The type of solvent also plays a role, as some substances are more soluble in certain solvents compared to others.
How can solids liquids and gases be made to contract?
Solids, liquids, and gases can be made to contract by reducing their temperature. Cooling these substances causes their particles to move more slowly, resulting in a decrease in volume. This decrease in volume leads to contraction of the material.
What liquids don't turn into gases?
Liquids that do not turn into gases at room temperature and pressure include oils, syrups, and certain types of molten metals. These substances have higher boiling points compared to water, which allows them to remain in liquid form.
Are hydrogen and helium gases?
They can be depending on the temperature and pressure. They can also be liquids and solids. At room temperature and pressure they are gases.
What is the effect of temperature on gases in liquids?
It is varied for each substance.
List two substances that are solids two that are liquid and two that are gases at room temperature?
aluminum and rock juice and milk oxygen and nitrogen
Gases form of Liquid or solid substances?
Usually of liquids through the process of evaporation.
How does the solubility of gases in liquids affected by changes in temperature?
Generally, the solubility of gasses in liquids go up as the temperature of the liquid goes down.
What are liquid and gases together called?
Liquids and gases together are referred to as fluids. Fluids are substances that flow and can take the shape of their container.
