Froggy Jumps Charles' Law ChallengeVersion en ligne Gas volume vs temperature basics par Muichiro Tokito 1 What does Charles' Law state about volume (V) and temperature (T) at constant pressure? a V is inversely proportional to T b V is directly proportional to T (in Kelvin) c V is independent of T 2 Which temperature scale must be used for Charles' Law measurements? a Kelvin b Fahrenheit c Celsius 3 For Charles' Law to apply, which quantities must stay constant? a Pressure and amount of gas (n) b Temperature and volume c Volume and pressure 4 What is the standard form of the Charles' Law equation? a V2/V1 = T2/T1 b P1/T1 = P2/T2 c V1/T1 = V2/T2 5 If V1 = 2.50 L at T1 = 298.15 K and T2 = 263.15 K, what is V2? a 3.00 L b 2.21 L c 1.75 L 6 A gas has V1 = 120 mL at 250 K and T2 = 500 K. What is V2? a 180 mL b 60 mL c 240 mL 7 What does 0 K represent? a Boiling point of water b Room temperature c Absolute zero, no molecular motion 8 Who conducted the first hydrogen balloon flight in 1783? a Jacques Charles b Marie Curie c Albert Einstein 9 In Charles' Law, how does increasing Kelvin temperature affect volume when P and n are constant? a Volume increases b Volume decreases c Volume stays the same 10 If the temperature doubles in Kelvin at constant P and n, what happens to V? a Volume doubles b Volume halves c Volume quadruples
