Interpretation:
When a given amount of air is let out of an automobile tire, it changes it volume and pressure simultaneously, and as a result of this, the temperature of the air changes. a derivative that stands for this change is to be written.
Concept introduction:
Pressure can be conveniently measured for gases and fluids. The pressure of a liquid or a gas is equal to the density of that liquid multiplied by the acceleration due to gravity and the height of the liquid above the certain point. The standard unit for pressure is Pascal (Pa). The motion of atoms and molecules generates heat or thermal energy and it is measured as ‘temperature’. This energy is found in all materials. Notably, the more motion the atoms or molecules have the more heat or thermal energy they may have. If the values of two variables such as temperature and pressure is found out, the value of other variable i.e., volume can be easily calculated.

- In the 1880s, Frederick Trouton noted that the enthalpy of vaporization of 1 mol pure liquid is approximately 88 times the boiling point, Tb, of the liquid on the Kelvin scale. This relationship is called Troutons rule and is represented by the thermochemical equation liquid gas H = 88 Tb, joules Combined with an empirical formula from chemical analysis, Troutons rule can be used to find the molecular formula of a compound, as illustrated here. A compound that contains only carbon and hydrogen is 85.6% C and 14.4% H. Its enthalpy of vaporization is 389 J/g, and it boils at a temperature of 322 K. (a) What is the empirical formula of this compound? (b) Use Troutons rule to calculate the approximate enthalpy or vaporization or one mole of the compound. Combine the enthalpy of vaporization per mole with that same quantity per gram to obtain an approximate molar mass of the compound. (c) Use the results of parts (a) and (b) to find the molecular formula of this compound. Remember that the molecular mass must be exactly a whole-number multiple of the empirical formula mass, so considerable rounding may be needed.arrow_forwardWhat is the kinetic energy of a single atom of mercury that has a speed of 200m/s?
