Final answer:
Using Charles' Law, we can determine that the volume of air at the cooler temperature of 20°C is approximately 0.935 L.
Step-by-step explanation:
To find the volume of air at the cooler temperature, we can use Charles' Law, which states that the volume of a gas is directly proportional to its temperature, as long as the pressure is constant.
We can set up the equation:
V1/T1 = V2/T2
Where:
V1 = initial volume of air = 1.0 L
T1 = initial temperature in Kelvin = 312 K
V2 = final volume of air (which is what we're trying to find)
T2 = final temperature in Kelvin = 293 K
Plugging in the values, we get:
1.0 L / 312 K = V2 / 293 K
Cross multiplying, we find:
V2 = (1.0 L * 293 K) / 312 K
Simplifying, the volume of air at the cooler temperature is approximately 0.935 L.
