Charles' Law

Cards (14)

Jacques Charles - the French scientist who made accurate observations on how the volume of the gas is related to temperature
What is constant when using the Charles' Law?
pressure
When temperature of a gas goes down, what happens to its volume?
goes down
What gas law does the graph shows?
Charles' Law
volume and temperature - quantities that are directly proportional in Charles' Law.
kelvin - the temperature scale that must be used when applying Charles' law.
How will you convert Celsius temperature to Kevin?
add 273.15 to Celsius temperature
What is the equivalent value of 35°C in Kelvin?
308.15K
What relationship between volume (V) and temperature (t) of a confined air can be drawn from the data?
The volume is directly proportional to temperature.
What is the temperature of the confined gas in degree Kelvin when its volume is 32 cm³?
423K
V1/T1 = V2/T2 - the mathematical statement of Charles' Law
A balloon with a volume of 250 mL at 25°C is submerged in hot water to obtain a temperature of 50°C. Find out what will happen to the volume of the balloon, provided the pressure remains the same.
The volume of the balloon will become higher than 250 mL.
A 420 mL of a sample of gas at 25.0°C is compressed to 210 mL. What is the temperature of the gas after compression? The pressure remains constant.
149K
A sample of helium gas is heated from 15.0°C to 30.0°C. This heating process causes the gas to expand to a volume of 585 cm³. What was the original volume of the helium gas?
556 cm³
