Why is water liquid at room temp but oxygen is gas at room temp?
Water molecules have stronger intermolecular forces (hydrogen bonding) that keep them together as a liquid at room temperature. Oxygen molecules have weaker intermolecular forces, so they stay as a gas at room temperature.
What type of bond makes water liquid?
Van der Waal forces determine the attractiveness of molecules to others outside of covalent and ionic bonds. For water, the dipole interaction between the slightly + hydrogen end of the molecules are attracted to the slightly - oxygen end.
Which shows substances placed in order from strongest to weakest attractive forces at room temperature?
At room temperature, substances can be ordered from strongest to weakest attractive forces as follows: ionic compounds (e.g., sodium chloride) exhibit strong ionic bonds, followed by polar covalent compounds (e.g., water) with dipole-dipole interactions, then nonpolar covalent compounds (e.g., hydrocarbons) which primarily experience London dispersion forces. Lastly, gases (e.g., oxygen) have the weakest attractive forces due to minimal intermolecular interactions.
Where does liquid oxygen come from?
Liquid oxygen is an industrial product.
How is a liquid different from a oxygen?
Oxygen can be liquid or a gas. It is just a different state of matter.
How does liquid oxygen boil?
Liquid oxygen boils when its temperature rises enough to overcome the attractive forces between oxygen molecules, causing them to transition from a liquid state to a gaseous state. This process, known as vaporization, occurs at a boiling point of -183 degrees Celsius for oxygen.
Why do oxygen and methane have low melting points?
The melting point of a substance depends, in part, on whether one or more intermolecular forces act to attract the molecules of the substance, and on the strengths of these forces. In the cases of the substances you mention these forces are absent or very small.
How do intermolecular forces affect the boiling of a liquid?
The stronger the forces, the more heat that must be added to boil the liquid
Why does oxygen have a low boiling point?
Oxygen has a low boiling point because it is composed of small, diatomic molecules held together by weak intermolecular forces. These weak forces are easily overcome by heat, causing oxygen to change from a liquid to a gas at a relatively low temperature of -183 degrees Celsius.
Why is lots of energy required to separate lithium and oxygen in lithiumoxide?
Separating lithium and oxygen in lithium oxide requires a lot of energy because it involves breaking strong chemical bonds between lithium and oxygen atoms. It takes significant energy to overcome the attractive forces holding these atoms together in a stable compound like lithium oxide.
What are the characteristic of matter?
Characteristics of matter -Particles of matterare infinitely small;have space between them;are continuously moving;have attractive forces between particles;have an increase in kinetic energy with an increase in temperature.On point 4 - gas particles are considered to have no attractive forces between one another and act totally independently of one another. However, there must be some attractive forces between particles as the pressure increases and/or the temperature decreases of gas would never condense to a liquid.
Why is water liquid at room temp but oxygen is gas at room temp?
Water molecules have stronger intermolecular forces (hydrogen bonding) that keep them together as a liquid at room temperature. Oxygen molecules have weaker intermolecular forces, so they stay as a gas at room temperature.

Does boiling water break covalent bonds?
Boiling water does not break the covalent bonds between the hydrogen and oxygen atoms in water molecules. Boiling water simply increases the kinetic energy of the water molecules, causing them to overcome the forces holding them together in the liquid phase and transition to the gas phase.
Why is the melting point of oxygen lower than that of sodium?
The melting point of a substance is determined by the strength of the forces between its atoms or molecules. Oxygen molecules are held together by weaker London dispersion forces and dipole-dipole interactions, resulting in a lower melting point compared to sodium, which is held together by strong metallic bonds. These differences in bonding lead to variations in the amount of energy required to overcome the intermolecular forces and transition from a solid to a liquid state.
Is a oxygen liquid or gas?
its a gas
