A 595 mL sample of chlorine gas at 24.7°C is held at constant pressure while it is heated and the volume of the gas expands to 876mL. What is the new temperature in Kelvin?
A) 83.7 K
B) 202 K
C) 365 K
D) 438 K

Respuesta :

Charles law gives the relationship between temperature of gas and volume. This states that the volume of gas is directly proportional to the temperature at a constant pressure.
[tex] \frac{V1}{T1} = \frac{V2}{T2} [/tex]
Parameters for the first instance is given on the left side and parameters for the second instance are given on the right side of the equation.
temperature should be given in K.
temperature in Kelvin = temperature in celcius + 273
24.7 °C + 273 = 297.7 K
595 mL / 297.7 K = 876 mL / T
T = 438.2 K rounded off is 438 K
Answer is D
