In an experiment to determine the thermal conductivity of a new metal alloy, a bar of the metal is completely surrounded by insulation and exposed to 701 W of constant heat energy at one end. The bar has a radius of 0.065 m and a length of 0.339 m. The entire set-up is place in a cold room and once the system has reached steady state conditions, the temperature at the hot end is measured to be 60.1°C and the temperature at the cold end is measured to be 12.4°C. What is the thermal conductivity (in W/m∙K) of the metal alloy [round your final answer to zero decimal places]?

1 kg of benzene is poured into a flask and heated to 353 K (the boiling point of benzeneat 1 atm.) using a heating element that has a power of 700 W (we ignore thatit's probably not so healthy and smart to do). After 5 minutes, when the benzene has stoodboiling point, the heating element is taken up, and the remaining mass of benzene in the flaskmeasured at 470 grams. Determine the enthalpy of vaporization of benzene.
3 Calculate ∆G for the process during which 10 mmol He(g) which initially occupies a volume of 500 cm3, expands isothermally to a final volume of 5 dm3 at 298.15 K.
The molar enthalpy of vaporization of a liquid at its normal boiling point is 39.16 kJ mol-1. When a liquid boils some part of the enthalpy is used in converting the liquid into vapor. The remaining is used in expansion work of the vapor against the external pressure. Calculate what percentage of the enthalpy of vaporization of this liquid is used for the expansion work. Assume that the vapor behaves ideally and that the molar volume of the liquid can be neglected when compared to the molar volume of the vapor. At the normal boiling point of liquid 466.6K, the pressure is 1.00 atm (exactly) by definition.

A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.) The temperature of the water bath is monitored, and it is determined from this data that 252. kJ of heat flows out of the system during the reaction. The position of the piston is also monitored, and it is determined from this data that the piston does 337. kJ of work on the system during the reaction.
