Is a gas at 1.4 atm pressure and 15 L volume, at -10 degrees Celsius and 1 mole the gas, an ideal gas, why or why not
To determine if a gas is ideal or not, we need to consider the conditions laid out, particularly, the temperature, pressure, volume, and the nature of the gas molecules.
The ideal gas law equation is given as:
PV = nRT
Where:
P is the pressure of the gas,
V is the volume of the gas,
n is the number of moles of the gas,
R is the ideal gas constant,
T is the temperature of the gas.
In this case, the gas is at a pressure of 1.4 atm, a volume of 15 L, and consists of 1 mole of gas. Let's assess each aspect's impact:
1. Pressure: The pressure value is provided and falls within the range of typical atmospheric pressures. Hence, it does not indicate any deviation from ideality for gases.
2. Volume: The volume is given as 15 L, which is not extremely large or small. It is within the range of applicability for the ideal gas law.
3. Moles: The gas consists of 1 mole, which is not an extremely high or low number. It also lies within the acceptable range for using the ideal gas law.
4. Temperature: The gas is at -10 degrees Celsius. However, for the ideal gas law, temperature needs to be expressed in Kelvin scale. The conversion from Celsius to Kelvin is performed by adding 273.15. So, -10 degrees Celsius is equal to 263.15 Kelvin.
Now, we can calculate if the gas is ideal using the ideal gas law equation:
PV = nRT
(1.4 atm) * (15 L) = (1 mole) * (R) * (263.15 K)
Using the equation, we can compare the left side and right side of the equation. If they are equal, then the gas is ideal.
However, since the ideal gas constant (R) is not provided, we cannot perform the calculation to conclusively determine if the gas is ideal or not.
Therefore, without knowing the value of the ideal gas constant (R), we cannot definitively determine if the gas is ideal or not.
