66. If the absolute temperature is doubled for a fixed mass of an ideal gas in a rigid walled container, what happens to the pressure?
     
A. remains constant P1V1      P2V2 
-------- = ------------  Combined Gas Law
n1T1       n2T2   
    

Rigid walled container   V1 = V2  
fixed mass                      n1  =  n2
    

P1      P2 
---- = -----
T1      T2 
 

    
P and T are directly proportional.  If the absolute temperature is doubled, the pressure is also doubled.

The Correct Answer is B.

B. doubles
C. quadruples
D. halves
