What did J. J. Thomson observe when he applied electric voltage to a cathode ray tube in his famous experiment? The stream of cathode ray particles was moving very slowly.
The glass opposite of the negative electrode started to glow.
The electric voltage had little effect on the stream of particles.
The tube contained two pieces of metal that served as electrodes.

it can be icreased by increasing pressure.

i believe the answer is a.

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.
