To calculate the volume of the tank after heating it and its contents to 40°C at constant pressure, we can use the ideal gas law equation:

PV = nRT

Where: P = Pressure (constant) V = Volume n = Number of moles of gas R = Ideal gas constant T = Temperature (in Kelvin)

First, let's convert the given temperatures to Kelvin: Initial temperature (T1) = 25°C = 25 + 273.15 = 298.15 K Final temperature (T2) = 40°C = 40 + 273.15 = 313.15 K

Since the pressure remains constant, we can write the equation as:

V1 / T1 = V2 / T2

Where: V1 = Initial volume V2 = Final volume

Now, let's rearrange the equation to solve for V2:

V2 = (V1 * T2) / T1

Given: V1 = 2.3 L T1 = 298.15 K T2 = 313.15 K

Substituting the values into the equation:

V2 = (2.3 * 313.15) / 298.15 V2 ≈ 2.41 L

Therefore, the volume of the tank after heating it and its contents to 40°C at constant pressure will be approximately 2.41 liters.
