A gas currently has a pressure of 17 atm, a volume of 96 L, and a temperature of 284 K. If its initial
pressure was 16 atm and initial volume was 84 L, what was the initial temperature?

The initial temperature was 234K

Explanation:

We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T

(P1xV1)/T1=(P2xV2)/T2

(16atmx84L)/T1= (17atmx 96 L)/284K

1344atmx L/T1= 5,75 atm x L/K

T1= 1344atmx L/5,75 atm x L/K= 233,74K

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.
