A. 1.01 is the accurate result
Because
The formula used is Pv= nRT
P=1 atm
V= 22.4 L
N= x
R= 0.0821
T= 273 K (since it’s standard temperature)
Thus, (1)(22.4)=(x)(0.0821)(273)
X= 1.001
Response: 2. When molecules with different speeds collide, heat is transferred from the faster ones to the slower ones.
Clarification: I hope this was useful!:)
