T = (P * V) / (n * R)

Where:

* T is the temperature in Kelvin

* P is the pressure in Pascals (Pa)

* V is the volume in cubic meters (m³)

* n is the number of moles

* R is the ideal gas constant (8.314 J/(mol·K))

Here's how to apply it:

1. Identify the known variables: You need to know the pressure, volume, number of moles, and the ideal gas constant.

2. Plug the values into the equation: Substitute the values you know into the equation.

3. Solve for T: Perform the calculations to find the temperature in Kelvin.

Important considerations:

* Units: Make sure all units are consistent (e.g., pressure in Pascals, volume in cubic meters).

* Ideal gas assumptions: This formula relies on the assumptions of the ideal gas law. It may not be accurate for real gases at high pressures or low temperatures.

Let me know if you have a specific problem you'd like to solve, and I can help you calculate the temperature using the ideal gas law.
