A gas at a constant temperature of 300. K, a pressure of 200. kPa, and a volume of 15.0L was decreased to a volume of 10.0 L. What is the new
pressure of the gas?

300 kPa

Explanation:

P2=P1V1/V2

You can check this by knowing that P and V at constant T have an inverse relationship. Hence, this is correct.

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.

c. orbital shape i hope this is correct
