Hi! I'm ChemGenius. I can help you with questions like: “What is the temperature of a gas at 1 atm in a 22.4 L container?” What chemistry question can I help you with today?

A balloon was inflated to a volume of 5.0 liters at a temperature of 70°C. It landed in an oven and was heated to 147°C. What is its new volume?
ChemGenius avatar

The new volume of the balloon after being heated to 147°C is 6.12 liters.

Ideal Gas Law

pv = nRT

Avogadro's Law

V1 / n1 = V2 / n2

Boyle's Law

P1V1 = P2V2

Combined Gas Law

P1V1/T1 = P2V2/T2

Charles's Law

V1 / T1 = V2 / T2

Henry's Law

P = kH * C

Graham's Law

r1 / r2 = √(M2 / M1)

Raoult's Law

P = P° * x

Van't Hoff Equation

ln(K2 / K1) = (-ΔH / R) * (1 / T2 - 1 / T1)

Nernst Equation

E = E° - (0.0592 / n) * log(Q)

Henderson-Hasselbalch Equation

pH = pKa + log([A-] / [HA])

Beer-Lambert Law

A = ε * c * l

Gibbs Free Energy Equation

ΔG = ΔH - TΔS

Hess's Law

ΣΔH°f(products) - ΣΔH°f(reactants)

First Law of Thermodynamics

ΔU = q + w

Gas Laws - Study Notes

Ideal Gas LawSarah M

The ideal gas law combines several gas laws into one equation:

PV = nRT

Boyle's Law

At constant temperature, pressure and volume are inversely proportionalAlex J

P₁V₁ = P₂V₂

Charles's Law

At constant pressure, volume and temperature are directly proportional:

V₁/T₁ = V₂/T₂Katie L

Remember: Temperature must always be in Kelvin for gas law calculations!

Pricing? pffft

You lucky ducks! During our beta period most of our features are free to use! Of course within reason, we want to keep our servers running!

After our beta period ends our goal is to keep some features free to use, while some features will require a small subscription fee to access. We realize that being a student can be tough, and we will be very mindful of any future pricing.
