Question

300 ml of gas at 27 Celsius is cooled to -3 at constant pressure the final velocity is

Answer 1

I assume you mean volume and not velocity.

At constant P, use (V1/T1) = (V1/T2). Remember T1 and T2 must be in kelvin. To convert celsius to kelvin do K = 273.15 + C

To determine the final velocity, we need to consider the ideal gas law and the relationship between temperature and velocity of gas molecules.

The ideal gas law states:

PV = nRT,

where P is the pressure, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature measured in Kelvin.

First, let's convert the temperatures to Kelvin. To convert Celsius to Kelvin, we add 273.15:

Initial temperature (T1) = 27°C + 273.15 = 300.15 K
Final temperature (T2) = -3°C + 273.15 = 270.15 K

Since the pressure is constant in this scenario, P1 = P2. Let's assume the pressure is P throughout.

Now, let's rearrange the ideal gas law equation to solve for velocity:

V = (nRT)/P

To calculate the final velocity (V2), we can rewrite the equation as:

V2 = (nR(T2))/P

To determine the number of moles (n) of gas, we need to know the molar mass (M) of the gas.

Once we have the molar mass, we can use the following formula to calculate the number of moles:

n = (mass of gas) / (molar mass)

However, since we only know the volume of the gas, which is unrelated to mass, we cannot directly calculate the number of moles or the molar mass. Therefore, we do not have sufficient information to determine the final velocity of the gas.
