1. When you first opened the bottle of coke the pressure of gas in the coke (increased/decreased) and the dissolved gas( stays in/leaves) the coke. 2. When you placed the coke in hot water , the pressure of gas in the coke (increased/decreased) and the dissolved gas( stays in/leaves) the coke 3. Therefore to increase the solubility of a gas in a liquid ( that is to make a gas more soluble in a liquid) you should( increase/ decrease) pressure ( increase/ decrease) temperature 4. Adding salt ( increase/ decrease) the solubility of gas in the liquid. This is due to the nucleation sites on the salt( rough/smooth) surface where the gas forms. (nucleation sites are places where a gas can make bubbles)

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
