Identify the ideal gas law equation: \( PV = nRT \).
Rearrange the equation to solve for temperature \( T \): \( T = \frac{PV}{nR} \).
Substitute the given values into the equation: \( P = 1.3 \text{ atm} \), \( V = 11.8 \text{ L} \), \( n = 0.52 \text{ mol} \), and \( R = 0.0821 \text{ L atm mol}^{-1} \text{ K}^{-1} \).
Calculate the value of \( T \) using the substituted values.
Ensure the units are consistent and check the calculation for any errors.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Ideal Gas Law

The Ideal Gas Law is a fundamental equation in chemistry that relates the pressure, volume, temperature, and number of moles of an ideal gas. It is expressed as PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Kelvin. This law allows us to calculate one of the variables if the others are known.

Units of Measurement

In the Ideal Gas Law, it is crucial to use consistent units. Pressure is typically measured in atmospheres (atm), volume in liters (L), and temperature in Kelvin (K). To convert Celsius to Kelvin, add 273.15. Ensuring that all units are compatible is essential for accurate calculations.

Gas Constant (R)

The gas constant (R) is a proportionality constant in the Ideal Gas Law, with a value of 0.0821 L·atm/(K·mol) when using atm for pressure and liters for volume. This constant allows for the conversion between the different units in the equation and is essential for solving for temperature or any other variable in the context of gas behavior.

An automobile tire has a maximum rating of 38.0 psi (gauge pressure). The tire is inflated (while cold) to a volume of 11.8 L and a gauge pressure of 36.0 psi at a temperature of 12.0 °C. On a hot day, the tire warms to 65.0 °C, and its volume expands to 12.2 L. Does the pressure in the tire exceed its maximum rating? (Note: The gauge pressure is the difference between the total pressure and atmospheric pressure. In this case, assume that atmospheric pressure is 14.7 psi.)

A weather balloon is inflated to a volume of 28.5 L at a pressure of 748 mmHg and a temperature of 28.0 °C. The balloon rises in the atmosphere to an altitude of approximately 25,000 ft, where the pressure is 385 mmHg and the temperature is -15.0 °C. Assuming the balloon can freely expand, calculate the volume of the balloon at this altitude.
