When we combine the three gas laws into one expression:
V is directly proprtional to T
P is directly propetional to T ---------> PV is directly proprtional to T
P is inversely proportional to 1/V
*******I do not understand how PV is directly proportional to T and how PV/T= constant. Is there a mathematical manipulation or something? Please explain.
PV=nRT replacing nR with c,a constant, then PV=cT
so PV is directly proportional to T
for part 1, divide
PV=cT by T
