The pressure of an ideal gas stays constant at 2.57 atm.
This ideal gas has a volume of 45.8 mL when it is at a
temperature of 37.0°C. What temperature will this ideal gas
be at when it contracts to 32.5 mL?

Answer:

[tex]T_2=-53.15\°C[/tex]

Explanation:

Hello there!

In this case, in agreement to the Charles' law which states that the volume and temperature relate to each other via a directly proportional relationship at constant pressure, we can write:

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

Thus, given V1, V2 and T1 (310 in Kelvin), we can solve for the final temperature as shown below:

[tex]T_2=\frac{T_1V_2}{V_1} \\\\T_2=\frac{310K*32.5mL}{45.8mL}\\\\T_2=220 K-273.15K\\\\T_2=-53.15\°C[/tex]

Best regards!
