Solids, Liquids and Gases Flashcards
1
Q
Formula for density and the units
A
Density = mass / volume
kg/cm³
2
Q
Formula for pressure and the units
A
pressure = force / area
pascals, Pa
3
Q
Pressure difference formula
A
pressure difference = height × density × gravitational field strength
4
Q
What is Absolute Zero
A
The lowest temperature where there is the least amount of kinetic energy
-273°C / 0K (kelvin)
5
Q
How to convert Kelvin into degrees Celsius
A
Temperature in Kelvin = temperature in °C + 273
6
Q
Temperature is directly proportional to…
A
Pressure
• more kinetic energy
•particles move faster and collide harder and more frequently
7
Q
Volume is inversely proportional to…
A
Pressure
• more space for particles to move
• fewer collisions between particles and container walls
(saying opposite is also correct)
