A 5.00 mL volume of methane gas is cooled from 60.0 °C to 30.0 °C.If the pressure remains constant,what is the final volume in milliliters?

According to Charles's Law, at constant pressure, the volume of a gas varies directly with its temperature in Kelvin. Therefore, we need to convert the temperatures to Kelvin: 60.0 °C + 273 = 333 K and 30.0 °C + 273 = 303 K. Then we can use the formula:

V1/T1 = V2/T2

where V1 and T1 are the initial volume and temperature, and V2 and T2 are the final volume and temperature. Plugging in the given values, we get:

5.00 mL / 333 K = V2 / 303 K

Solving for V2, we get:

V2 = 5.00 mL x 303 K / 333 K = 4.55 mL

Therefore, the final volume is 4.55 mL.
