Consider a particle that has two states: bonded to a surface, or non-bonded (released). the nonbonded state is higher in energy by an amount ε0. (a) explain how the ability of the particle to bond to the surface contributes to the heat capacity, and why the heat capacity cv = ∂hei ∂t v depends on temperature. (b) compute the heat capacity cv in units of n k if t = 300 k and ε0 = 1.2 kcal/mol, which is about the strength of a weak hydrogen bond in water.

chemistry sucks a**

explanation:

i don't know people like to fight everywhere rip.

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
