What else can I help you with?
When you suck from a straw you make your mouth bigger so what happens to the air pressure in your mouth?
When you suck from a straw, you increase the volume of your mouth. This decrease in pressure inside your mouth creates a vacuum that draws liquid up the straw.
How do you get from a liquid to a gas?
To get from a liquid to a gas, you need to increase the temperature of the liquid to its boiling point. This added heat energy breaks the intermolecular forces holding the liquid molecules together, allowing them to escape into the atmosphere as a gas. This process is called vaporization or evaporation.
If a liquid is added to a beaker the pressure exerted by the liquid on the bottom of the beaker?
increases due to the increased weight of the liquid. This is because the liquid's weight creates a force that is spread out over the bottom of the beaker, leading to an increase in pressure.
Why does vapor pressure increase with an increase in temperature?
PV=nRT where P=pressure, V=volume, n=no. of moles, R=gas constant, T=temperature(K) since volume and the number of moles remain constant, they can be ignored and we can assume:- that P is proportional to T and thus if temperature is increased, pressure will also increase.
An increase in the temperature of a contained liquid?
An increase in temperature of a contained liquid will cause its molecules to move faster and further apart, leading to an expansion in volume. This expansion can potentially increase pressure inside the container if it is sealed, and may also change the physical state of the liquid (e.g. from solid to liquid, or liquid to gas) depending on the specific substance.
What does Bernoulli's principles states?
Bernoulli's principle states that an increase in the speed of a liquid results in a decrease in pressure, and a decrease in the speed of a liquid results in an increase in pressureBernoulli's Principle states that as the velocity of a fluid increases, the pressure exerted by that fluid decreases.
What is the term for the Boiling of a liquid caused by decrease in pressure rather than by an increase in temperature?
This is known as "boiling point elevation." It occurs when the boiling point of a liquid increases due to a decrease in pressure, such as at higher altitudes.
What three things can you do to increase the rate of dissolving a gas in a liquid?
Increase the amount of liquid Decrease the temperature of the liquid Increase the pressure of the gas
How does pressure exerted by a liquid increase with depth?
It increases linearly, assuming the liquid is incompressible.
Does increases in pressure increase the compressibility of liquids?
No, increases in pressure do not increase the compressibility of liquids. Liquids are considered to be nearly incompressible under most conditions, meaning their volume does not change significantly with changes in pressure.
When a gas is dissolved into a liquid what happens when the pressure increases?
More gas dissolves into the liquid.
How does pressure affects the solubility of oxygen gas in a liquid?
ONLY IN GASES, as pressure increases, so does soluability. Think soda: soda containers are pressurized in order to stuff as much CO2 as possible in the liquid. In solids and liquids, changes in pressure make very small changes to soluability.
Does density increase decrease or stay the same if temp and mass of a liquid increase?
Depends on the other conditions. If the volume remains constant, the density will remain the same (but the pressure will increase). If the pressure remains constant, the volume will increase - and therefore the density (mass / volume) will decrease.
In a pressure chamber filled with gas above a liquid solution a decrease in volume causes?
AN increase n pressure, an increase in gas concentration in the solution
When you suck from a straw you make your mouth bigger so what happens to the air pressure in your mouth?
When you suck from a straw, you increase the volume of your mouth. This decrease in pressure inside your mouth creates a vacuum that draws liquid up the straw.
How does vapor pressure affect volume?
Vapor pressure is a measure of a substance's tendency to escape into the gas phase. When vapor pressure increases, more molecules escape from the liquid phase into the gas phase, leading to an increase in volume. Conversely, a decrease in vapor pressure can lead to a decrease in volume as fewer molecules transition into the gas phase.
How do you get from a liquid to a gas?
To get from a liquid to a gas, you need to increase the temperature of the liquid to its boiling point. This added heat energy breaks the intermolecular forces holding the liquid molecules together, allowing them to escape into the atmosphere as a gas.
