The fastest animal in the world is the peregrine falcon, known for reaching speeds of over 240 miles per hour while diving. This speed is crucial for its hunting strategy, allowing it to catch prey efficiently. The peregrine falcon is a widely distributed species found in diverse environments around the globe.

Explanation
Understanding Gay-Lussac's Law We are asked to identify the variables in Gay-Lussac's law from the given options. Gay-Lussac's law describes the relationship between pressure and temperature of a gas when the volume and number of moles are kept constant.
Identifying the Variables The options provided are:
pressure and volume
pressure, temperature, and volume
pressure and temperature
volume, temperature, and moles of gas Based on the definition of Gay-Lussac's law, the variables are pressure and temperature.
Examples
Gay-Lussac's law is useful in understanding how pressure changes with temperature in a closed container, like an aerosol can. If you heat an aerosol can, the pressure inside increases. If the pressure exceeds the can's limit, it can explode. This principle is also important in designing pressure cookers and internal combustion engines, where controlling pressure and temperature is crucial for safety and efficiency. For example, if you have a gas at initial pressure P 1 and temperature T 1 , and you change the temperature to T 2 , the new pressure P 2 can be calculated using the formula T 1 P 1 = T 2 P 2 .
