History
Who discovered the relationship between the relationship between gas volume and temperature, which later became known as Charles’ Law
Jacques Charles
What is the relationship between the absolute temperature and volume at constant pressure
Volume of gas is directly proportional to the absolute temperature
What balloon relies directly on Charles's Law to rise
Hot Air Balloon
If temperature doubles under constant pressure what happens the volume of gas
Doubles
Who published Charles's Law in 1802
Joseph Louis Gay-Lussac
Formula for Charles's Law
V₁ / T₁ = V₂ / T₂
Why is it more likely for car tires to pop during a hot day
The gas of volume inside the tire increases expanding the tiring causing it to pop more easily
Two balloons, one filled with helium one filled with hydrogen, have the same volume. Both are heated at constant pressure. According to Charles’s Law, how do their volume changes compare?
The volume changes are the same
Who inspired Charles with the invention of the hot air balloon
Joseph and Etienne Montgolfier
How to convert degrees celsius to kelvins
K = °C + 273.15
How might temperature-controlled incubators help support the lungs of premature infants?
Warming of the air increases its volume and improves lung inflation, helping support effective ventilation and reducing respiratory stress.
A student plots temperature (C) with volume (L) but observes a non-linear correlation. Why?
Temperature is in Celsius not Kelvin
What time period was Charles living in when discovering this law? How is this context relevant?
Age of Enlightenment. Scientists started to emphasize measurements, experimentation, and math. Instruments like thermometers and barometers were becoming reliable.
Why will Charles’ Law not work at absolute zero? What does it predict?
It predicts the volume of the gas to be zero. However, matter must occupy space, so Charles' Law cannot be applied.
Why might a scientist observe a non-linear correlation between temperature and volume at low temperatures?
Charles’ Law assumes ideal gases, but in real life, gases have a condensation point. At low temperatures, gas particles slow down and intermolecular forces become significant, causing the gas to condense into a liquid before reaching absolute zero. As a result, the volume does not decrease linearly with temperature, and the relationship predicted by Charles’ Law becomes non-linear.
Why must temperature always be in Kelvins in Charles's Law
Kelvin starts at absolute zero, allowing for temperature and volume to be proportional
