What else can I help you with?
A sample of a gas has a volume of 2.0 liters at a pressure of 1.0 atmosphere When the volume increases to 4.0 liters at constant temperature the pressure will be?
For this you would use Boyle's Law, P1V1 = P2V2. The first pressure and volume variables are before the change, while the second set are after the change. In this case, the volume is being changed and the pressure has to be solved for. P1 = 1.00 ATM V1 = 2.0 L P2 = Unknown V2 = 4.00 L P1V1 = P2V2 1.00(2.0)=4.00P P= .5 ATM
If the volume of a cylinder is reduced from 8.0 liters to 4.0 liters the pressure of the gas in the cylinder will change from 70 kilopascals to what?
Assuming the temperature remains constant, we can use Boyle's Law which states that pressure and volume are inversely proportional at constant temperature. If the volume is halved from 8.0 liters to 4.0 liters, the pressure will double from 70 kilopascals to 140 kilopascals.
If you have three liters of gas at a certain kelvin temperature and a certain pressure. The kelvin temperature triples and the pressure stays the same. What is the gas volume?
According to Charles's Law, the volume of a gas is directly proportional to its Kelvin temperature when pressure is constant. Therefore, if the Kelvin temperature triples, the gas volume will also triple, so the gas volume will be 9 liters.
What if the volume of a cylinder is reduced from 8.0 liters to 4.0 liters what should be the pressure of the gas in the cylinder?
If the volume of a gas is reduced from 8.0 liters to 4.0 liters, and the temperature remains constant, the pressure will double according to Boyle's Law. Therefore, the pressure of the gas in the cylinder should increase by a factor of 2.
What is the difference between lpm and slpm?
"Lpm" stands for liters per minute, while "slpm" stands for standard liters per minute. Standard liters are measured at a specific set of conditions, typically at standard temperature and pressure (STP). The difference between lpm and slpm is that slpm takes into account the variations in gas density that can occur due to changes in temperature and pressure.
How do you convert liters to atmospheres?
You don't. Liters is a unit of volume, atmospheres is a unit of pressure.
How many moles of gas are present when the volume of gas is 100.0 liters the pressure is 3 atmospheres and temperature is -10C?
The answer is 13,89 moles.
What is the pressure of 4 moles of helium in 50 liters tank at 308 K?
The pressure is 2,02 atmospheres.
Ideal gas law measures volume in what?
atmospheres
What are the most common units of pressure volume and temperature?
pressure -- Torr which is equivalent to mmHg, Pascals or kPa, atmospheres, psi, inches Hg Volume -- usually liters Temperature -- Kelvin or Celsius which must be converted to Kelvin to be used in any gas law equations
What variables and units are used to describe a gas?
Pressure, volume and temperature, and moles of gas are the four principal variables to describe a gas (for example, see related questions on Ideal Gas Law and others). The standard units are: Pressure: atmospheres (atm) Volume: liters (L) Temperature: Kelvin (K) Number of moles are measure in, well, moles.
A sample of a gas has a volume of 2.0 liters at a pressure of 1.0 atmosphere When the volume increases to 4.0 liters at constant temperature the pressure will be?
For this you would use Boyle's Law, P1V1 = P2V2. The first pressure and volume variables are before the change, while the second set are after the change. In this case, the volume is being changed and the pressure has to be solved for. P1 = 1.00 ATM V1 = 2.0 L P2 = Unknown V2 = 4.00 L P1V1 = P2V2 1.00(2.0)=4.00P P= .5 ATM
What volume will 125 g of CO2 occupy?
It depends on temperature and pressure. Assuming 25.0ºC and 1.00 atmospheres then 125 g CO2 occupies 54.7 dm3.
A 4.0 liter container of gas in initially at a pressure of 16 ATM what will the pressure be if the voume is changed to 1 liters at constant temperature?
Use Boyle's Law, applicable for ideal gases at constant temperature, to solve this problem: P1*V1 = P2*V2
Is Potassium a metallic solid at STP?
That is the element potassium at STANDARD TEMPERATURE AND PRESSURE. Standard temperature is 273 K and standard pressure is 1 atm.
How can you change the volume of a liquid?
- by the variation of the temperature- by the variation of the pressure
If the volume of a cylinder is reduced from 8.0 liters to 4.0 liters the pressure of the gas in the cylinder will change from 70 kilopascals to what?
Assuming the temperature remains constant, we can use Boyle's Law which states that pressure and volume are inversely proportional at constant temperature. If the volume is halved from 8.0 liters to 4.0 liters, the pressure will double from 70 kilopascals to 140 kilopascals.
