The enthalpy of vaporization of a liquid is 30 kJ "mol"^(-1) and the entropy of vapourisation 75 JK^(-1) mol^(-1) .The boiling point of the liquid at 1 atm is ___ View Solution The entropy change for vaporisation of a liquid is109.3JK−1mol−1. The molar heat of vaporis...
What is the work done against the atmosphere when 25 grams of water vaprorizes at 373K against a constant external pressure of 1atm ? Assume that steam obeys perfect gas law. Given that the molar enthalpy of vaporization is 9.72kcal/mole, what is the change of internal energy in the abov...
I know some rigging and packing technicians that have been doing this for years but they aren't engineers, so they won't know nothing about enthalpy of vaporization. Plus they are our client so I'm supposed to be smart engineer with the equations. Regarding the heat required to evaporate...
Because atmospheric pressure is relatively constant, the pressure in the lungs must change to create airflow between the lungs and the outside environment. During inhalation (inspiration), the diaphragm and supporting muscles (intercostal muscles) contract, which results in an expansion of the thoracic...
C_3H_8 + 5 O_2 \to 3 CO_2 + 4 H_2O The enthalpy of reaction is -2202.0 kJ/mol. How much energy (in kilojoules) will be released if 93.48 g of propane is burned? (Molar mass of propane = 44.11 g Calculate the mass of water produced when 5.54 grams of butane reacts w...
Answer to: Calculate the change in internal energy (Delta E) for a system that is absorbing 35.8 kJ of heat and is expanding from 8.0 L to 24.0 L...
1Enthalpy and the Loss of Heat Scientists use the term 'change in enthalpy' to describe a gain or loss in energy by a compound or reaction. If the pressure is kept constant, the change in enthalpy can be generally thought of as a change in heat. When a liquid is cooled, it has a ...
