Question

Exactly 10.0 L of O₂ at -25°C is heated to 100.0°C. What is the new volume if the pressure is kept constant?

Answer 1

The new volume of the gas, when the pressure is kept constant, is 15.15 L.

Step-by-step explanation:

To find the new volume of the gas when the pressure is kept constant, we can use the combined gas law equation: PV/T = constant. Since the pressure is constant, we can write the equation as V1/T1 = V2/T2. The initial volume is 10.0 L at -25°C, and the final temperature is 100.0°C. We need to convert the temperatures to Kelvin by adding 273.15. Using the equation, we can solve for V2:

V2 = V1 * (T2/T1)

V2 = 10.0 * (373.15/248.15) = 15.15 L
