Answer:
 151.1J 
Explanation:
Given parameters: 
Mass of iron  = 6.21g 
Initial temperature of iron  = 25°C 
Final temperature of iron  = 79.8°C
Unknown: 
Amount of heat = ? 
Solution: 
The amount of heat require to cause this temperature can be determined using the expression below;
     H  = m c (T₂ - T₁)
H is the amount of heat 
m is the mass 
c is the specific heat capacity 
T is the temperature
     Specific heat capacity of iron 0.444J/g°C
Insert the parameters and solve; 
      H  = 6.21 x 0.444 x (79.8 - 25) 
      H   = 151.1J

We have to convert 0.18 km into feet
First, we need to know the conversions:
1 inch = 2.54 cm (exact)
1 pound = 454 g
1 Liter = 1.0b quarts
1 feet = 12 inches
1 galion = 4 quarts
1 pound = 16 ounces
0.18 km x (1 feet/12 inches) x (1 inch/2.54cm) x (1000 m/1 km) x (100 cm/1 m) = 590 ft
Answer: 590 ft (2 significant figures)
