To solve this you will use the general gas equation

P1V1/T1=P2V2/T2

Cross multiply and remove v from the equation since it is constant

P1T2=P2T1

T2=77+273k=350k
T1=27+273k=300k
Let p1 be 1

P2= 350/300 =1.166

P1/T1=P2/T2
if u cross miltifly the formula will be
P1T2=P2T1
divide both side by T1
P2=P1T2/T1
P2=77+273/27+273
P2=350/300
P2=1.16
approximately 1.2

The solution is wrong.The P2 is supposed to be 77 + 273 not 27+ 273

To convert celsius to kevin is 273
but i don't think the answer@myschool gave us is correct...p1/T1 =p2/T2
T1=27+273=300
T2=77+273=350
Then;P1/300=p2/350 u'll cross multiply
so it will be like 350p1=300p2....divide the numbers by 350p1
350p1/350p1
300p2/350p1

so we have p=0.857...that is 0.86

thats what i thought oo..u can add yours if u think what i solved is wrong no problem with that
