Yes.....The continetal plates shifting would cause either disaster...
Answer:
V1=<u>2.5ft3</u>
<u>V2=1ft3</u>
n=1.51
Explanation:
PART A:
the volume of each state is obtained by multiplying the mass by the specific volume in each state
V=volume
v=especific volume
m=mass
V=mv
state 1
V1=m.v1
V1=2lb*1.25ft3/lb=<u>2.5ft3</u>
state 2
V2=m.v2
V2=2lb*0.5ft3/lb= <u> 1ft3</u>
PART B:
since the PV ^ n is constant we can equal the equations of state 1 and state 2
P1V1^n=P2V2^n
P1/P2=(V2/V1)^n
ln(P1/P2)=n . ln (V2/V1)
n=ln(P1/P2)/ ln (V2/V1)
n=ln(15/60)/ ln (1/2.5)
n=1.51
