To solve this problem, we can use the Gay-Lussac's Law formula, which relates pressure and temperature of a gas in a rigid container:
P1/T1 = P2/T2
where P1 is initial pressure, T1 is initial temperature in Kelvin, P2 is final pressure, and T2 is final temperature in Kelvin.
First, let's convert the temperatures to Kelvin:
T1 = -100.0 + 273.15 = 173.15 K
T2 = 200.0 + 273.15 = 473.15 K
Now, plug the values into the equation and solve for P2:
55 kPa / 173.15 K = P2 / 473.15 K
P2 = (55 kPa * 473.15 K) / 173.15 K = 148.75 kPa
So, the final pressure will be approximately 148.75 kPa when the temperature is increased to 200.0°C.
P1/T1 = P2/T2
where P1 is initial pressure, T1 is initial temperature in Kelvin, P2 is final pressure, and T2 is final temperature in Kelvin.
First, let's convert the temperatures to Kelvin:
T1 = -100.0 + 273.15 = 173.15 K
T2 = 200.0 + 273.15 = 473.15 K
Now, plug the values into the equation and solve for P2:
55 kPa / 173.15 K = P2 / 473.15 K
P2 = (55 kPa * 473.15 K) / 173.15 K = 148.75 kPa
So, the final pressure will be approximately 148.75 kPa when the temperature is increased to 200.0°C.
