"Piv-nert"
Quick Math
What is true? What is false?
100
1000 mL
What is 1 Liter?
100
Balloon in a beaker with water expands. Hint wink: Temperature!
What happens if we heat up the beaker?
100
Boyle's Law.
What is PV = k or P1V1 = P2V2?
100
P = 1.2 atm V = 2.5 L n = ? T = 25° C
What is n=PV/RT = 0.12 mol
100
When using the piv-nert equation, we can use KPa for pressure.
What is true?
200
Degree Celsius + 273
What is Kelvin?
200
Temperature decreases (given that the pressure is constant).
What happens if the volume decreases?
200
Pressure
What is nRT/V?
200
P = 0.947 atm V = ? n = 2.0 mol T = 20° C
What is nRT/P = 51 L
200
If the pressure is constant, volume and temperature are indirectly proportional to each other.
What is false?
300
1 atm and 0 degree Celsius
What is STP?
300
Marshmallow expands in a vacuum.
What happens if we decrease the pressure in the vacuum?
300
Relationship between Pressure and volume (moles and temperature are constant).
What is PV = k or P1V1 = P2V2?
300
I have a balloon that can hold 100 liters of air. If I blow up this balloon with 3 moles of oxygen gas at a pressure of 1 atm, This is the temperature of the balloon.
What is T = PV/nR = 100/(3*.0821) = 406.2 K
300
When temperature is constant, as pressure increases, volume decreases.
What is true?
400
What is 760 torr?
What is 1 atm? What is 760 mm Hg? What is 101.325 kPa?
400
Egg will cook faster (when boiled). Hint wink: mountain/valley?
What happens if we cook the egg in the mountains?
400
These law are what the ideal gas law are made of.
What is combination of PV = constant, n1/V1 = n2/V2, V/T = constant?
400
This is the pressure in a 212 Liter tank containing 23.3 kg of argon gas at 25 degree Celsius.
What is 67.3 atm?
400
The number that I told you to remember before we begin playing was 19.
What is false?
500
R
What is 8.314 x 10^-2 (kPa*L/(K*mol))? What is 8.21 x 10^-2 (L*atm/(mol*K))?
500
Exception: What happens to the pressure cooker if it does not have the relief valve which releases steam?
Steam cannot escape, pressure will increase until the volume of the pressure cooker cannot handle it anymore, and will explode. In other words, the system wants to decrease "n", so that it can decrease pressure.
500
Partial pressure.
What is when more than one gas is in a container, each contributes to the whole as if it were the only gas present. (So add up all of the pressures of the individual gases, and you get the whole pressure of the system.)?
500
If you were to take a volleyball scuba diving with you THIS would be its NEW VOLUME if it started at the surface with a volume of 2.00L, under a pressure of 752.0 mmHg and a temperature of 20.0°C. On your dive you take it to a place where the pressure is 2943 mmHg, and the temperature is 0.245°C.
What is 0.477 L.
500
One assumption of the ideal gas is that molecules have intermolecular force and occupy volume.
What is false? Ideal gas - molecules have no intermolecular force and occupy no volume.
