Unknown Story

Charle's Law, or Volume – Temperature, is an experimental gas law that describes how gases expand when heated. The law asserts that at constant pressure, the volume of a given quantity of gas is precisely proportional to the kelvin temperature. The law simply states that as the temperature rises, so does the volume. Any change in Kelvin temperature would cause the volume of the gas to alter as well.
Who came up with this law?
Jacques Cousteau, a scientist, was honored with the law's title.
V T (kelvin) at constant pressureV/T =K (constant), thus V1/T =KFinal equations are V1/T1 = V2 /T2
What is Charles Law's mathematical expression?
Excellent! T1 is the starting temperature and T2 is the final temperature, whereas V1 is the initial volume and V2 is the final volume. Keep in mind that temperature should be expressed in Kelvin, thus what is the Kelvin formula?
The formula for converting Celsius to Kelvin is K= C + 273.15
Let's solve this problem using Charles Law.1. At 25.0 C, Kr gas has a volume of 1.75 L. If the temperature is raised to 50.0 C, calculate the volume of the gas. What are the presumptions?
Given the following conditions: V1=1.75 L, T1= 25.0 C, T2= 50.0 C, V2=? Solution: KT1 = 25.0 C + 273.15 = 298.15 KT2 = 50.0 C + 273.15 = 323.15Formula: V1/T1 = V2 /T2Substitution and cross multiply=1.75 L = V2 298.15 K 323.15 Kfinal solution =1.90 L
