Considering the Charles's Law, theinitial temperatureis 451 K or 178 °C.Definition of Charles's LawCharles's Law consists of therelationshipthat exists between thevolume and temperatureof a certain amount of ideal gas, which is maintained at a constant pressure, by means of a proportionality constant that is applied directly.For a given amount of gas at a constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases because the temperature is directly related to the energy of the movement of the gas molecules.In summary, Charles's law is a law that says that when the amount of gas and pressure remain constant, theratiobetweenvolume and temperaturewill always have the same value:V÷T=kConsidering the initial situation 1 and the final situation 2, the following is true:V₁÷T₁=V₂÷T₂Initial temperatureIn this case, you know:V₁= 2.65 LT₁= ?V₂= 1.75 LT₂= 25 °C= 298 KReplacing inCharles' law:2.65 L÷T₁= 1.75 L÷298 KSolving:2.65 L= (1.75 L÷298 K)× T₁2.65 L÷ (1.75 L÷298 K)= T₁451 K = 178 °C= T₁Finally, theinitial temperatureis 451 K or 178 °C.Learn more aboutCharles's Law:brainly.com/question/4147359#SPJ3...
