The kinetic theory of gases predicts that the thermal conductivity of a gas equals the product of the heat capacity at constant volume times the viscosity; this theory also predicts that the viscosity varies as the square root of temperature and is independent of pressure.

For the statements in them, put T if they are true and F if they are false. a) ( ) When a certain mass of ice melts at 0ºC, its density decreases. In this case, due to the first law of thermodynamics, the variation of the internal energy will be smaller than the heat involved in the process.b) ( ) During a process involving an ideal gas, you know the initial iternal energy and the final internal energy during the process. So you can know if the energy variation internal gas during the process is due to the work performed or the heat transferred.c) ( ) For a temperature increase of ∆T, a certain amount of ideal gas requires 30J when heated to constant volume and 50 J when heated to constant pressure. In thisIn this case, it is correct to state that the work performed by the gas in the second situation is 20 J.d) ( ) The higher the temperature of an ideal gas in a fixed volume V, the lower the free middle path of its molecules.e) ( ) When a system loses heat and performs work during a…
