What else can I help you with?
Why is there no gas pressure inside a vacuum?
Gas pressure is caused by the molecules of gas striking the walls of a container, or in the case of Earth's atmosphere, the molecules of air hitting the earth. In a vacuum, there are no gas molecules. No molecules, no pressure.
Which molecules difuse through the lipid portion of the plasma membrane?
Only nonpolar (hydrophobic) molecules can pass through the bi-lipid membrane. For example, hormones are nonpolar, and they can pass through the membrane.
What is the splitting of water molecules into hydrogen and oxygen molecules an example of?
The splitting of water molecules into hydrogen and oxygen molecules is an example of a chemical reaction known as electrolysis. This process involves passing an electric current through water to separate it into its constituent elements, hydrogen and oxygen.
Which is an example of gas effusion?
One example of gas effusion is the release of a gas through a small hole in a container, such as when air slowly escapes from a balloon. Another example would be the diffusion of gas molecules through a porous membrane, like the way oxygen and carbon dioxide diffuse in and out of our lungs during respiration.
Methane gas diffuses through air because the molecules are?
Methane gas diffuses through air because the molecules are small, light, and have high kinetic energy which allows them to move and spread out easily in the air. This process occurs due to the random movement of gas molecules from an area of high concentration to an area of low concentration until they reach an equilibrium.
Can you give me a example of a sentence using the word randomly?
The names were chosen randomly out of a hat.She sprinkled salt randomly over the icy driveway.The dandelions are scattered randomly through the field.The coach chose the players randomly and not according to skill level.
What occurs when molecules are distributed evenly through a solid liquid or a gas?
When molecules are evenly distributed through a solid, liquid, or gas, we say that the substance is in equilibrium. In a solid, the molecules are tightly packed and vibrate in place. In a liquid or gas, the molecules move freely and randomly.
What goes through the cell?
Nonpolar molecules (example: lipids) Small polar molecules such as water
Which is an example of effusion?
An example of effusion is the process by which a gas escapes through a tiny hole in a container into a vacuum, as seen in the flow of gas molecules from a pressurized canister when the nozzle is opened.
Why is there no gas pressure inside a vacuum?
Gas pressure is caused by the molecules of gas striking the walls of a container, or in the case of Earth's atmosphere, the molecules of air hitting the earth. In a vacuum, there are no gas molecules. No molecules, no pressure.

Can you provide an example of conduction and explain how heat is transferred through this process?
An example of conduction is when you touch a hot pan on the stove. Heat is transferred through conduction as the molecules in the pan vibrate and collide with the molecules in your hand, transferring heat energy from the pan to your hand.
What molecules during osmosis does not move across the membrane One example?
Large molecules such as proteins are typically unable to move across the membrane during osmosis. One example is starch molecules, which are too large to pass through the membrane pores.
Which is an example of gas effusion?
One example of gas effusion is the release of a gas through a small hole in a container, such as when air slowly escapes from a balloon. Another example would be the diffusion of gas molecules through a porous membrane, like the way oxygen and carbon dioxide diffuse in and out of our lungs during respiration.

Why when a water molecule and an oxygen molecule are put in the same container and do not attract?
Water molecules and oxygen molecules have different intermolecular forces. Water molecules are attracted to each other through hydrogen bonding, while oxygen molecules are attracted through weaker dispersion forces. This difference in attractive forces results in water molecules clustering together and oxygen molecules clustering together, rather than mixing uniformly.
