Question

One of the coldest temperatures recorded in a natural setting was in Antartica. What is the temperature in Kelvin units Celsius units Oil spreads to make a film 120 nm thick (2 significant figures). How many square kilometers of ocean would to covered by a sick from a barrel of oil? (1 barrel = 31.5 U.S. gallons) Find the equivalent length in kilometers of the thickness of the slick. Find the equivalent volume in cubic kilometers of the barrel of oil. Answer the question using the results of a) and b).

Explanation / Answer

From deg.F =9/5*C +32= 1.8C+32

C = (F-32)/1.8

Given Deg.F =-128.5

C= (-128.5-32)/1.8 =-89.2 deg.C

K= deg.C+273.15= -89.2+273.15=183.95 K

b)

Thickness of oil film= 120mm

1mm =10-3m,   120mm =120/1000m =0.12m

1m= 10-3 Km, 0.12m= 0.12*10-3 km

1 Barrrel = 31.5 US gallon

1 Gallon =3.785 L

! Barrel = 31.5*3.785 L =119.23 L

1L= 10-3 m3

119.23 L= 119.23*10-3m3

1m =10-3 Km

1m3= (10-3)3   =10-9 km3

119.23*10-3m3 = 119.23*10-9 km3

Square kilometer = Volume./thickness = 119.23*10-9/0.12*10-3 =0.00099358 km2
