Explanation:
The atoms of hydrogen have smaller mass than oxygen. Thus their speeds have to higher in order to produce the same average kinetic energies.
Answer:
182.70K
Explanation:
Using the general gas equation as follows:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = 0.0821 Latm/Kmol
T = temperature (K)
Based on the provided information, P = 5 atm, V = 12L, n = 4 moles, T =?
PV = nRT
5 × 12 = 4 × 0.0821 × T
60 = 0.3284T
T = 60/0.3284
T = 182.70K

A battery is an example of a voltaic cell that is used daily.
Physical change is the color, shape stuff like that and chemical change is once it’s changed it can’t go back
