Use the ideal gas law, PV=nRT, in which P= pressure, V= volume, n= number of moles, R= the gas constant, and T= temperature. In this problem you know V, T, R, and n. What you are trying to figure out is the P.

P= Unknown

V= 35.0 L

n= 6.50 moles

R= .082057 L ATM/mol K

T= 305 K

PV= nRT

P35.0=6.50(.082057)305

P= 4.65 ATM

This is an ideal gas law problem, PV=nRT, where p = 14 atm, V = 35 L, n = 9 mol, R = 0.082 L atm/mol K.

Rearrange the equation to solve for T:

T=(PV)/(nR)

T=(14 atm x 35 L)/(9 mol x 0.082 L atm/mol K) = 700 K if your teacher is counting significant figures, 664 K if she isn't.

What will the pressure inside the container become if the piston is moved to the 1.80 L rm L mark while the temperature of the gas is kept constant?

This problem can be solved with the ideal gas law. The original pressure and volume of the container are proportional the final pressure and volume of the container. The original pressure was 1 atmosphere and the original volume was 1 liter. If the final volume is 1.8 liters, then the final pressure is 0.55 atmospheres.

What is the temperature of 9 moles of an ideal gas in a 35 liter container at 14 atm pressure-?

This looks suspiciously like a homework question! Temp of 8 mol of ideal gas in a 32 L container at 12 atm pressure? pV = 12 * 32 = 384 L.atm nRT = 8 * 0.082 * T = 0.656 * T L.atm T = 384/0.656 = ~516 K That should provide the template for your answer!

What is the temperature of a 100 liter container having 1 mole of an ideal gas at a pressure of 20 kilo pascals?

To find the temperature, we can use the ideal gas law equation: PV = nRT. Rearranging the equation to solve for temperature (T), we have T = (PV) / (nR), where P is the pressure, V is the volume, n is the number of moles, and R is the ideal gas constant. Plugging in the given values (P = 20 kPa, V = 100 L, n = 1 mol, and R = 8.314 J/(molยทK)), we find that the temperature is approximately 239 K.


What is the pressure of gas in a 30 liter container at 49 degrees c?

Gas pressure depends on volume, temperature, AND the amount of gas. You didn't give an amount of gas, so there is no way to answer your question.

What happens to the pressure of a heated substance?

When the volume of an "ideal gas" increases AND the amount (number of moles*) of gas remains constant, the temperature of the gas will decrease. One relevant assumption for an "ideal gas" is that it is "dry" - no water vapor (humidity) in the sample One relevant equation is the Ideal Gas Law P*V = n*R*T When P = pressure in atmospheres V = volume in liters n = amount of the Ideal Gas, in moles R = the ideal, or universal, gas constant = 0.08206 L*atm / mol * K which is read as "liter-atmospheres per mole-Kelvin" T = the absolute temperature in K, "Kelvins" *A "mole" is 6.022×1023 atoms or molecules of a substance. This is known as "Avogadro's Number"
