In an annealing (heat treatment) process, copper rods ( = 8933 kg/m3 , k = 401 W/m ∙ K, c = 385 /kg ∙ K, = 1.17 × 10−5m2 /s) with a radius of 0.05 meters are treated by drawing them through an industrial high temperature furnace. The gases ( = 0.4213 kg/m3 , k = 0.08491 W/m ∙ K, c = 1292 /kg ∙ K, = 1.56 × 10−4m2 /s) in the furnace are maintained at 1300K. The heat transfer coefficient in the furnace is 150W/m2 ∙ K. The copper rods enter the furnace at a uniform temperature of 350K throughout the rods.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
