Calculadora da Lei dos Gases Ideais

The Ideal Gas Law Calculator solves the equation PV = nRT, which relates pressure (P), volume (V), amount of substance (n), gas constant (R), and temperature (T) for ideal gases. It allows you to calculate any of these variables when the others are provided, being useful in thermodynamics and chemistry studies.

The operation is simple: enter the known values in the corresponding fields, leaving empty the field you want to calculate. The calculator applies the formula PV = nRT, rearranging it as needed. For example, to calculate pressure, use P = nRT/V. Remember to use compatible units (e.g., pressure in atm, volume in L, temperature in K, n in mol).

Use this calculator in situations such as determining the volume of gas in a balloon at a given temperature and pressure, or finding the pressure exerted by a gas in a closed container. It is ideal for physics and chemistry students, engineers, and technicians working with gas systems.

Caution: the ideal gas law is an approximation that works well for real gases at low pressures and high temperatures. Under extreme conditions (high pressure, low temperature), real gases deviate from this behavior. Always check unit consistency: temperature must be in Kelvin, and the gas constant R should be chosen according to the units of pressure and volume (e.g., R = 0.082057 L·atm/(mol·K)).
