Section E Solids, Liquids And Gases Flashcards
1
Q
How do you calculate pressure?
A
Pressure = force / area
2
Q
How do you calculate the pressure difference?
A
Pressure difference = height (m) x density x gravity
3
Q
What is density measured in?
A
Kg/m3
4
Q
Give the numerical value of absolute zero of temperature in degrees Celsius.
A
0° Kelvin = -273°C
5
Q
What is Brownian Motion?
A
When particles move in a random, zigzag motion. It supports particle theory.
6
Q
What is the equation for finding the constant in particle theory?
A
Constant = Pressure x Volume
7
Q
What is the equation for density?
A
Density = mass / volume
