Hi :)
I'm having difficulty with finding the relationship between specific heat, c, and thermal conductivity, k and cannot answer these questions -
Six objects are placed in a 500 F (260 C) oven and allowed to reach thermal equilibrium. Each object has a mass of 1.0 kg . The specific heat and thermal conductivity of each substance are denoted by c and k.
Rank these objects on the basis of their temperatures when removed from the oven.
Rank from largest to smallest. To rank items as equivalent, overlap them.
Steak
c: 3500 J /(kgC)
k: 0.2 J /(smC)
Wood
c: 1700 J /(kgC)
k: 0.1 J /(smC)
Aluminium
c: 900 J /(kgC)
k: 220 J /(smC)
Glass
c: 837 J /(kgC)
k: 0.8 J /(smC)
Silver
c: 235 J /(kgC)
k: 420 J /(smC)
Iron
c: 448 J /(kgC)
k: 80 J /(smC)
And also Question 2.
Each of the objects is immediately dunked in an identical tub of cold water. The tubs are quickly sealed and insulated. Rank the objects on the basis of their temperature on reaching equilibrium with the water.
Rank from largest to smallest. To rank items as equivalent, overlap them.
with the same objects.
