If you know the total number of moles of gas on each side of an equation you can determine?
How equilibrium will be affected by changes in pressure or volume.
What is Boyle's Law equation?
Pressure X Volume = constant
Can you work out pressure from volume?
No. For a gas, temperature also comes into the equation.
The volume of a given mass of an ideal gas at constant pressure is?
directly proportional to the Kelvin temperature
What is the equation for boyles law?
Pressure x Volume = Constant (at a constant temperature).
Give a mathematical equation that shows the relationship between pressure and volume?
p = k/v or pv = k k is a constant p is pressure v is volume
A container filled with gas has a volume of 185 ml and a pressure of 310 mm Hg The desired new volume is 74.0 ml What is the required new pressure?
the answer is 72.1 Hg
While a balloon is being filled if the temperature of the air in the balloon decreases what happens to its volume?
volume decreases considering the pressure is constant
What is perfect gas equation?
This is also known as the ideal gas equation, PV = nRT Where P is the pressure of the gas, V its volume, n is the number of moles of gas, R is the gas constant, and T is the absolute temperature.
Is the graph created by Pressure vs Volume an exponential graph when constant in temperature?
It depends, you have to know which variable (Temperature/Pressure/Volume) is constant, see here http://hypertextbook.com/physics/thermal/pressure-volume/
What are the four variables in the ideal gas law?
Pressure, volume, temperature & the amount of gas.
What is the formula of Boyles law?
The mathematical equation for Boyle's law is PV = k or you could say P1V1=P2V2. P IS the pressure of the system. V is the volume of the gas. k is a constant value representative of the pressure and volume of the system. **It just states that pressure and volume are inversely proportional when temperature is held constant (does not change). In other words, as volume increases pressure decreases and vice-versa (when temperature is constant).** Also, an easy way to remember all of the laws (Boyle's, Charles', and Gay-Lussac's) is to remember one equation: The Ideal Gas Equation, which happens to be PV=nRT. P=pressure, V=volume, n=number of moles, R=constant (varies with certain units, for example, when using torrs or mm Hg it would equal 62.4), and T=temperature. You can make basic assumptions from this equation, for example, you know that when temperature is held constant that if pressure increases volume must decrease (which happens to be Boyle's Law).
