Charles Law Flashcards
1
Q
Charles’s law
A
The volume of a fixed quantity of gas is directly proportional to the temperature in Kelvin if the pressure of the gas remains constant
2
Q
Relationship in words
A
Volume is directly proportional to the absolute temperature (temperature in Kelvin)
3
Q
Why does the graph not go through the origin
A
The graph is in °C and volume is only directly proportional to temperature in Kelvin, not Celsius. There is only a linear relationship between volume and temperature in Celsius. The graph has to be extended to -237°C in order to be directly proportional
4
Q
The relation between the Kelvin and Celsius scale
A
t (in °C) = T (in K) - 273
T (in K) = t (in °C) + 273
5
Q
Equation and formula
A
Equation: V1/T1 = K
Formula: V1/T1 = V2/T2
