Principles of Thermodynamics [EXP-7769]

The process whereby molecules bind to a metallic surface is called adsorption. Here, molecules are adsorbed on Pt nanoparticles. The specific heat of an average Pt nanoparticle is $C_V$ . The heat transferred to an average Pt nanoparticle during the adsorption of molecules is $Q_{if}$ . Determine the temperature increase $ΔT_{if} = T_f − T_i$ of an average Pt nanoparticle, assuming that the system consisting of the nanoparticles and the gas is isolated.

Numerical Application:

C_V = 1.4 · 10^{−18} J K^{−1}, Qif = 6.5 · 10^{−16} J.
