A thermocouple is embedded 10 mm from the surface of a thick slab of material initially at 30C. The surface was suddenly brought to a temperature of 100 C by exposure to boiling water. The thermocouple measures a temperature of 65C, 2 min after the surface is brought to 100C, what is its thermal conductivity of the material

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
