According to the law stating that all perfect gases alter in volume by l/273th of their volume at 0°C for every 1°C temperature variation under constant pressure ____________________?
Show answer Hide answer
Answer: E. Charles’ law
Explanation
Charles's law states that gas volume changes proportionally with absolute temperature. Specifically, ideal gases expand by 1/273 of their 0 degree volume per degree Celsius rise. This linear relationship applies when keeping system pressure strictly constant. French physicist Jacques Charles formulated gas volume and temperature relationships in the 1780s. Absolute zero temperature represents minus 273.15 degrees Celsius on the thermal scale. Ideal gas laws combine pressure, volume, and temperature into predictable equations.
Thermodynamic cycle analysis uses Charles's law to predict gas expansion in cylinders. Hot air balloons operate on the principle that heating gas increases its volume and buoyancy. Engineering calculations account for temperature-induced volume changes in gas storage tanks. Joule's law relates internal energy changes to temperature in ideal gas expansions. Boyle's law establishes the inverse relationship between gas pressure and volume at constant temperature. Gay-Lussac's law relates gas pressure directly to temperature at constant volume conditions.
