What is true about a sample of 02 compared to a sample of H2 if both are at T= 25C (m = molecular mass, v= ave. velocity)
a) V(H2) > V(O2) since (mv^2)H2 = (mv^2)O2
b) V(H2) < V(O2) since (mv^2)H2 = (mv^2)O2
c) V(H2) = V(O2) since (mv^2)H2 = (mv^2)O2
d) V(H2) = V(O2) since T(H2) = T(O2)
e) V^2(H2) = V^2(O2) since T(H2) = T(O2)
