Answer:
d. 573 K
Step-by-step explanation:
To find the temperature at which the pressure in Flask 1 is the highest, you can use the ideal gas law (PV = nRT), where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature in Kelvin.
Since the number of moles (n), volume (V), and gas constant (R) are constant for Flask 1, the pressure (P) will be highest when the temperature (T) is highest.
Among the options provided:
d. 573 K
So, at 573 Kelvin, the pressure in Flask 1 will be the highest.
