What is the temperature in kelvin of a gas if it is allowed to expand from 1.50 L to 4.50 L? The initial temperature is 10.0°C and pressure is constant throughout the change. Which equation should you use?

Respuesta :

Answer: 1) 849 K

2) [tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]

Explanation:

Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

[tex]V\propto T[/tex]    (At constant pressure and number of moles)

[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]

[tex]V_1[/tex]= initial volume = 1.50 L

[tex]V_2[/tex]= final volume = 4.50 L

[tex]T_1[/tex]= initial temperature =[tex]10^0C=(10+273)K=283K[/tex]

[tex]T_2[/tex]= final temperature =?

[tex]\frac{1.50 }{283}=\frac{4.50}{T_2}[/tex]

[tex]T_2=849K[/tex]

Answer: Equation: T2 = V2/V1 T1

Final temperature: 849 K
