Question

What is the combined gas law? When do you apply it?

David Collins · Accepted Answer

this question asks you what is the combined gas law? So it takes into account your understanding of a lot of the gas laws that were introduced to use, such as Charles Law and Boyle&#x27;s Law, and combines them into a single gas law. The combined gas law states that pressure times volume divided by temperature, will be equal to a constant. So that means the pressure of a gas under one set of conditions multiplied by its volume divided by its temperature, will be equal to the pressure of the gas under the second set of conditions multiplied by its volume, divided by its temperature. Because both of these are equal to the same constant. So you would use this combined gas law when you have a gas under one set of conditions and you have one of the three and you have one or more of the three variables changing. Typically one or two variables changing. You could have a particular, uh, a nen initial pressure volume and temperature, and then maybe the pressure changes to a new pressure. The temperature changes to a new temperature, and you&#x27;re asked to calculate the new volume or, you know, the initial pressure, volume and temperature of the gas and the pressure take changes to a set value and the volume changes to a set value and you&#x27;re asked to solve for the new temperature.

this question assets what the combined gas law is and when it&#x27;s useful. The combined gas law is a combination of Boyle&#x27;s law in Charleston. So Boyle&#x27;s law said that&#x27;s P one Ponzi one is equal to P. Two times be, too, so that pressure and volume have an inverse relationship. And Charles is Law said that volume and temperature had a proportional relationship. So they this one said that the one over T one was equal to be to over t two. So we&#x27;ve combined these together. So we end up with P one times. The one over T one is equal to P two times the two over t two. So we&#x27;ve kept the inverse relationship of pressure and volume and kept the proportional the direct proportional relationship of volume and temperature and just combined all three variables into one equation. So this is useful when we have the same gas on same moles, same amount of that gas, um, under different conditions, so you could change the all three variables and as long as you had five out of the six here so you could change, you could have one start with one pressure and volume and temperature and you could change the pressure and the volume and still find them be able to find the new temperature or change the volume in the temperature and find the new pressure and same thing if you wanted to find a new volume and a new pressure and temperature. So this is useful when you have the same amount of the same gas under very different conditions to find the missing variable here.

Mehrnaz Siavoshi · Answer

Chapter 11 Problem 17 asks us about the combined gas law so they combined Gas law expresses the relationship between pressure, volume and temperature. If we have a fixed amount of a gas and specifically, it states that the pressure times the fall you divided by the temperature is always constant, and we write the constant as K in this example. So if you increase pressure, volume will decrease or temperature will increase, and you confined similar relationships using the other variables in this equation.

this question asks what the ideal gas law is and when it is useful. So the ideal gas law is p the equals n a r t. So P is pressure. The is volume and is the number of moles of the gas are is a constant and T is temperature. This is useful when we have three out of the four variable. So the four variables R, P, B and and T since our is a constant if we have three out of four variables that we can always find the fourth variable. So if you know the pressure volume and a number of moles of the gas, you can calculate the temperature or same thing with any of the other few variables that you have three variables. Three variables you can find the fourth one.

Hello Today we&#x27;ll talk about Chapter 12 Question eight, which asks us to relate the basic gas laws. So we have. Boyle&#x27;s law P one V one equals P to V two at constant temperature, temperature and constant numbers of moles we have. Charles is long. The one over t one equals V two over tea, too, at constant pressure and numbers of moles. The gala sacks Long States p one over t one equals P two over tea too. And that is a constant volume. It&#x27;s This is a constant volume and numbers of moles. And finally we have other God Rose law, which States V is directly related to a proportionality, constant times, the number of moles of the gas. And so putting these together, we can relate them using the ideal gas law which states that PV equals N R and T, where P is the pressure of the gas as described both by boils and the gala sacks laws and has this relationship to temperature and similarly, this relationship with volume and temperature from the Charles Law and finally has a scaler counseling coefficient here of our that balances the units and acts is a scaler PV equals n Artie&#x27;s the ideal gas law. And so if we know any three of these four variables where this is a constant, so are is a constant, and these four are the variables, and lastly, the pressure. If we know any three of these, we can use the ideal gas law to calculate the last one. And similarly, if we know fewer or we know that there are constants, we can kind of condense to determine one of these basic laws.

So the question is, what? Gas laws air combining the ideal gas law. So in the ideal law, there are three mean, uh, gas loss to discuss them. So this is boils just to do with pressure and volume, a inverse relationship. And the other one is Charles Law just to do with for you and Temperature. And, um, they are directly proportional on the last one is sorry. One second. I think it&#x27;s all the guard Rose Law, uh, food God throws. And this has to do with volume and number of moles. This is a direct the report.

Problem 1 Easy Difficulty

What is the combined gas law? When do you apply it?

Answer

The combined gas law is P1V1 / T1 = P2V2 / T2, and is is a relationship between changing pressure, volume, and temperature for gasses. This law can be used for problems where pressure, volume, and temperature all change rather than one of them staying constant.
