Question

Calculate the volume of gas at 175 C degrees if its volume is 132 mL at 24 C degrees at a constant pressure

Answer 1

Answer: volume of gas at 175°C = 18.10mL.

Explanations

Given :

• Temperature (T1 = 175°C

,

• Volume (V1 ) = 132 mL

,

• Temperature (T2) = 24 °C

,

• Volume 2 = ....mL?

We will consider Charles law "volume of an ideal gas at constant pressure is directly proportional to the absolute temperature"

• Represented as :

`(V_1)/(T_1)=\text{ }(V_2)/(T_2)`

Replacing the given parameters into chales law equation , we get that V2 =

`\begin{gathered} V_2=(V_1*T_2)/(T_1) \\ \text{ = }\frac{132mL\text{ * 24 }\degree C}{175\degree C} \\ \text{ =18.10 mL} \end{gathered}`

This means that the volume of gas at 175 = 18.10mL.
