Suppose 0.5 kg of blood flows from the interior to the surface of Johns body while he is exercising. The released energy is 2000 J. The specific heat capacity of blood is 4186 j/kg what is the temperature difference between when the blood arrives at the body surface and returns back to the interior of the body

Ahypothetical metal has an orthorhombic unit cell for which the a, b, and c lattice parameters are 0.413 nm, 0.665 nm, and 0.876 nm, respectively. (a) if there are 8 atoms per unit cell and the atomic packing factor is 0.536, determine the atomic radius (in nm). (b) if the density is 3.99 g/cm3, calculate the metal's atomic weight (in g/mol).
