We know the ideal gas relation..PV=nRT
Where p=pressure
V=volume
n=number of moles of gas
R=gas constant
T=temperature
Using this equation we can write..

Which of the following is true? Group of answer choices 1. An increase in the moles of a gas will cause a decrease in the volume of a gas at constant temperature and pressure. 2. None of these choices is correct. 3. An increase in the moles of a gas will cause an increase in temperature at constant pressure and volume. 4. A decrease in the temperature of a gas will cause an increase in the pressure of a fixed...

from gay-lussac's law, If you increase the temperature of a gas (with constant moles and volume) what do you expect will happen to the pressure? Look up Boyle's Law. For an ideal gas at constant temperature and moles, if you increase the volume of the gas what do you expect will happen to the pressure of the gas? How else is the pressure-volume relationship typically plotted?

Combined Gas Relationship Since the Ideal Gas Law produces a constant (R), it can be used to look at a gas sample in which initial and final conditions have changed. The combined gas relationship is as follows P.V R=P.V2 n, T n2 T2 where P, Vi,and T, and n, are the initial pressure, volume, temperature, and number of moles of gas. The final conditions are represented by P, V2, T2 and n2. If any of the conditions in the initial...

Which of the following statements is consistent with Boyle's Law concerning an ideal gas? At constant temperature and moles, a plot of pressure versus the inverse of volume is linear. At constant temperature and moles, a plot of volume versus pressure is linear At constant pressure and volume, a plot of temperature versus moles is linear. At constant temperature and pressure, a plot of moles versus volume is linear At constant pressure and moles, a plot of temperature versus volume...

Which of the following is true about a 0.200 mol sample of nitrogen gas and a 0.200 mol sample of argon gas that are at 1.20 atm and an initial temperature 55.0°C when the temperature changes to 400 K? Assume constant volume for the container under both of these temperature conditions. The density of both gases will increase. There will be more collisions between the gas molecules and the pressure in the container will decrease. None of these choices is...

If you decrease the moles of gas while holding volume and pressure constant, the temperature will __(decrease/increase) because moles and temperature are __(directly/inversely) related to an ideal gas.
