Activity 1 1/19/11 Ideal Gas Law

What is the tire pressure at -20°F compared to 90°F, assuming the starting pressure was 32 psi?
 25.6psi


  32psi     =       ?psi
305.2K            244.3K



( 244.3K) ( 32psi )    =    (   ?psi)         ( 244.3K)
               (305.2K )          ( 244.3K)
                      
                                               244.3K cancel each other on this side

 ( 244.3K) ( 32psi )    =       ?psi
                (305.2K)         

32psi divide into 305.2K, then multiply 244.3 K, result is 25.6 PSI
