Describe the effect the following has on the measurement and explain the mechanism of this effect: reducing the size of the stationary phase particles in liquid chromatography. Briefly describe the factors affecting vapor pressure. Discuss the effect of the ion...
How does the entropy of a system change for the following process: A vapor condenses to a liquid. How does entropy change with volume and number of particles? If you increased the volume by multiplying the original by 20, and had 45 particles, what would the entropy c...
How does the entropy of a system change for the following process: A liquid boils. When water changes from liquid to vapor the change in entropy is a) negative b) positive c) cannot be determined d) zero How does the entropy of a system change for the followi...
The thermometers can be classified as the liquid and the dry thermometer. The degree of the hotness and the coldness is measured with the help of the thermometers. One end of the thermometer has a thin-walled glass bulb filled with mercury....
Electronic Transition Selection Rule: The selection rules are the sets of changes occurring in the quantum numbers due to the transition of one or more electrons from one state to another. The transition probability of electrons can never be zero. ...
Thermodynamics is a branch of physics that is responsible for the study of macroscopic systems and their thermal equilibrium, that is, the interaction between heat and the manifestations of energy that occur in the universe. Thermodynamics deals with th...
Entropy Change The entropy is defined as the randomness of the reaction, it is positive if the number of moles of the products are greater than the moles of reactants, or more gaseous molecules are formed. If the volume of the system ...
