What else can I help you with?
A sample of water was found to boil at 15C in a closed container What must have been true for this to occur?
The pressure must have been extremely low in the container.
A sample of water vapor was found to condense at 105C in a closed container What must have been true for this to occur?
The pressure must have been higher than 1 ATM in the container.
What will cause a decrease in pressure in a closed container?
A decrease will occur if the lid of the container is opened.
Can evaporation occur in a closed container?
Yes, evaporation can still occur in a closed container, but the rate of evaporation will eventually slow down because the amount of water vapor in the container will reach an equilibrium with the liquid water. At this point, the rate of condensation will equal the rate of evaporation.
Can vapor pressure occur in open container?
Yes, vapor pressure can occur in an open container. Vapor pressure is the pressure exerted by a vapor in equilibrium with its condensed phase in a closed system. In an open container, vapor can still form above a liquid or solid substance, but it will not reach equilibrium as it can escape into the surrounding environment.
What reversable reactions occur in the container?
There are a couple reversible reactions that occur in the container. For example, one of the reactions is that gas can be reversed to a solid.
Where will the greatest increase in pressure occur if you squeeze the middle of an upright closed plastic bottle?
The greatest increase in pressure will occur at the middle of the bottle where you are applying the squeezing force. This is because applying a force to a closed container will compress the air inside, leading to an increase in pressure at the point where the force is being applied.
Why must a container or system be closed or equilibrium to be established?
A container or system must be closed to prevent the exchange of matter with the surroundings, ensuring that all relevant interactions and reactions occur within a defined environment. This isolation allows for the establishment of equilibrium, where the rates of forward and reverse processes equalize, resulting in stable concentrations of reactants and products. In an open system, external influences can disrupt this balance, making it impossible to achieve true equilibrium. Therefore, maintaining a closed system is essential for accurate observations and calculations in thermodynamics and chemical reactions.
Why would having a larger sample size be a better idea than having a samll sample size when doing an experiment?
less bias and error occur when sample size is larger
What is formed when two substances are in the same container but chemical reactions occur?
A mixture
Why do you store oily rags in a tightly sealed container?
You store them in a sealed container to prevent them from igniting. The oil and the air create a chemical reaction which creates heat, so after the oxygen is spent in the closed container, the process cannot be completed, therefore no fire.
Why does the pH Chang in a refrigerated urine sample?
Probable however some fermentation occur.
