Is the amount of substance in a certain volume the pressure?
No, the pressure is the force exerted by the substance on the walls of its container. The word that comes to mind for "amount of substance in a certain volume" is concentration, though it might also be a somewhat awkward way of describing density.The amount of substance in a certain volume is the density of the substance. Pressure means the force applied in a unit area. So the amount of substance in a certain volume is not the pressure.
Every charged particle produces a?
It produced a magnetic field. If it's charged, it can be negative OR positive. It's magnetic because if they're both alike signs (both positive or both negative) they repel like magnets. If one particle is positive and one is negative, they attract like magnets.
When something goes from a solid directly to a gas what is it called?
The process of a substance changing from a solid directly to a gas is called sublimation. This occurs when the substance's vapor pressure exceeds its atmospheric pressure at a certain temperature, allowing it to transition from a solid state to a gaseous state without passing through the liquid phase.
Is carbon dioxide a sublime substance?
No, carbon dioxide is a gaseous substance at room temperature and pressure. Sublimation is the process where a substance transitions directly from a solid to a gas without passing through the liquid phase. CO2 can also undergo sublimation under certain conditions.
What is colorless and bubbles with acid and often used in cement and lime?
The substance described is hydrochloric acid, a colorless liquid that produces bubbles when it reacts with certain materials such as cement and lime. It is commonly used in construction and industrial processes for cleaning and etching surfaces.
Passing an electric current through a certain substance produces oxygen and sulfur This substance cannot be a?
This substance cannot be water, because passing an electric current through water, in a process called electrolysis, produces hydrogen and oxygen gas, not oxygen and sulfur.
While conducting an experiment you discover a certain substance passing out of a cell by diffusion what might you conclude about the concentration of this substance?
If a substance is passing out of a cell by diffusion, it suggests that the concentration of the substance is higher inside the cell than outside. This movement is driven by the substance's tendency to move from an area of higher concentration to an area of lower concentration to reach equilibrium.
What causes a magnetic field to be set up around a wire?
Passing an electric current through a wire will produce an external magnetic field. This is because the electrons have spin and this spin is what produces the field. Spinning electrons (of certain characteristics) also produce the magnetic field of permanent magnets. And no spinning electrons, no magnetic field.
Is the amount of substance in a certain volume the pressure?

How does cigarette effect the body?
Cigarette produces a certain amount of a substance called tar in our lungs which causes cancer. After an year this tar becomes so much in amount that it can cause any disease in our body
The amount of one substance in a certain volume of another substance is called?
concentration

Why can't Pikachu use Roar of Time and Shadow Force?
Because those aren't Electric Pokemon moves. Certain Pokemon of certain categories can only do certain moves. Pickachu is Electric so he can perform Electric moves only.

How many molecules are in certain substances?
it depends on the substance
