What are the four properties that describe a gas?
Pressure (P), Volume (V), Temperature (T), and Amount (n).
What is pressure (P) in the context of gases?
The force exerted by gas against the walls of the container.
What is volume (V) in the context of gases?
The space occupied by the gas.
What does temperature (T) determine in gases?
The kinetic energy and rate of motion of the gas particles.
What does amount (n) refer to in the context of gases?
The quantity of gas present in a container.
What are the units of measurement for pressure?
Atmosphere (atm), mm Hg, torr, pascal.
What are the units of measurement for volume?
Liter (L), milliliter (mL).
What are the units of measurement for temperature?
Celsius (°C), Kelvin (K).
What are the units of measurement for amount (n)?
Grams (g), moles (mol).
How is gas pressure defined?
As a force acting on a specific area.
What is the formula for pressure (P)?
Pressure (P) = Force / Area.
What is the conversion for 1 atm in mm Hg?
1 atm = 760 mm Hg.
What is the definition of volume in gases?
The three-dimensional space occupied by a gas.
How does the shape of a gas compare to solids and liquids?
Gases take the shape of their container and have the volume of the container.
What are common units of volume?
mL, L, m³, cm³.
What is the freezing point of water in Celsius?
0°C.
What is the boiling point of water in Celsius?
100°C.
What is the temperature conversion formula from Celsius to Fahrenheit?
F = (9/5)C + 32.
What is the temperature conversion formula from Fahrenheit to Celsius?
C = (F - 32) × (5/9).
What is the temperature conversion formula from Celsius to Kelvin?
K = C + 273.15.
