Answer:

To determine the new pressure inside the flask when the temperature increases to 150°C, we can use the combined gas law. The combined gas law relates the initial and final conditions of pressure, volume, and temperature for a given amount of gas.

The combined gas law equation is:

(P1 × V1) / (T1) = (P2 × V2) / (T2)

Where:

P1 = Initial pressure

V1 = Initial volume

T1 = Initial temperature (in Kelvin)

P2 = Final pressure (unknown)

V2 = Final volume (which remains constant in this case)

T2 = Final temperature (in Kelvin)

First, let's convert the initial temperature of 0°C to Kelvin:

T1 = 0°C + 273.15 = 273.15 K

Next, we convert the final temperature of 150°C to Kelvin:

T2 = 150°C + 273.15 = 423.15 K

Since the volume (V1 = V2) remains constant, we can simplify the equation to:

P1 / T1 = P2 / T2

Now, we substitute the given values:

P1 = 685 torr

T1 = 273.15 K

T2 = 423.15 K

685 torr / 273.15 K = P2 / 423.15 K

Simplifying the equation:

P2 = (685 torr * 423.15 K) / 273.15 K

P2 = 1058.5 torr

Therefore, the pressure in the flask would be approximately 1058.5 torr when the temperature is increased to 150°C.
