Ideal gas law slides title: PV = nRT, ideal gas conditions, deriving the law and practice questions, with kettle image
Opening slide to preview the lesson's four parts
Intro to PV = nRT: guiding question on how pressure, temperature and volume relate to moles of gas in an ideal gas sample
Hook question to open discussion before defining terms
Variables in PV = nRT: units for pressure, volume, moles and kelvin temperature, plus R as 8.3145, 0.0821 and 62.4
Reference notes on units; pick the R value that matches
Ideal gas conditions: four assumptions, equal-size particles, elastic collisions, tiny volume, no intermolecular forces
Note-taking slide on when real gases behave ideally
Deriving PV = nRT by combining Boyle's, Charles' and Avogadro's laws as volume proportionalities, with values of R
Walk-through linking earlier gas laws to the new equation
Practice problem: find the mass of sulfur dioxide in a 2.50 L container at 120 kPa and 26°C; students list the givens
Try-it-first prompt before revealing the givens
Sulfur dioxide mass problem with givens listed: P = 120 kPa, V = 2.50 L, T = 299 K, R = 8.31, mass unknown
Reveal step to check students' list of known values
Practice problem: find the volume of 1.00 g of water vapor at its 100°C boiling point and 101 kPa; students list givens
Second practice prompt for partners or individual work
Water vapor volume problem with givens set out: mass 1.00 g, T = 373 K, P = 101 kPa, R = 8.31, volume unknown
Reveal step so students can compare their known values
