Is the amount of pressure in a gas measured in pascals?
Yes.The amount of gas is determined by its pressure, volume, and temperature. The equation is:PV = nRTwhere:P = pressure, measured in pascals (the SI derived unit of pressure)V = volumen = amount of substance of gas (moles)R = universal gas constantT = temperature
What is the ratio of RH?
Relative humidity (RH) is the ratio of the partial pressure of water vapour to the saturation vapour pressure of water at the same temperature. Relative humidity depends on temperature and the pressure. Very roughly speaking, it is a ratio of the amount of water vapour in the air compared to the total amount of water vapour that it possible for that air to contain.
How do you find the volume of an object using the graduated cylinder?
By pouring a set amount of water into the cylinder then addin the object and seeing how much the volume changes. The amount of change is the volume of the object.
How close is your estimated value measured temperature of the water?
how are temperature the amount of heat transferred and change in in temperature of related
What is the density of 1000g of water?
The density of something does not depend on the amount of the substance you have, the density of 1 gram of water is the same as the density of 100000000 grams of water. The density of pure water at standard temperature and pressure is 1.
What are the four variables in the ideal gas law?
Pressure, volume, temperature & the amount of gas.
Is it true that above the temperature no amount of pressure will casue a gas to liquefy?
The critical temperature of a gas is the temperature at or above which no amount of pressure, however great, will cause the gas to liquefy.
Is the amount of pressure in a gas measured in pascals?
Yes.The amount of gas is determined by its pressure, volume, and temperature. The equation is:PV = nRTwhere:P = pressure, measured in pascals (the SI derived unit of pressure)V = volumen = amount of substance of gas (moles)R = universal gas constantT = temperature
What is the effect of the temperature on the vapour pressure?
When temperature is increased the amount of molecules evaporated is increasef and as a consequence condensation is also increased so vapour pressure increases.
When the temperature of the gas changes from cold to hot the amount of pressure is .?
In a closed system the pressure is higher.
When the temperature of the gas changes from cold to hot the amount of pressure is?
In a closed system the pressure is higher.
What are 3 factors that affect gas behavior?
amount of gas, temperature, and volume.Further answerI would add pressure to that.
The amount of pressure in a gas is measured in pascals true or false?
True.The amount of gas is determined by its pressure, volume, and temperature. The equation is:PV = nRTwhere:P = pressure, measured in pascals (the SI derived unit of pressure)V = volumen = amount of substance of gas (moles)R = universal gas constantT = temperature
How much pressure will compressed CO2 create when released in an air cylinder?
Whatever amount of pressure was used to compress the CO2 originally, can be reached (or nearly reached) when it is released into an air cylinder.
What is the amount of salt in a substance?
This is called the solubility at a given temperature and pressure.
What is the amount of dissolved salts in a substances?
This is called the solubility at a given temperature and pressure.
What is the temperature if the gas pressure is constant?
At isobaric (pressure) expansion (volume increase) the temperature will increase because V is proportional to T for the same amount of gas (closed container) at constant pressure.
