Solids, Liquids, and Gases

Question 1

How do you calculate pressure?

Answer 1

Pressure = Force / Area, p = F/A

Question 2

How do you calculate density

Answer 2

Density = mass / volume, p = m/V

Question 3

Density practical

Answer 3

Measure mass of substance
Measure length width and height to calculate volume
If its an irregular solid find the volume by pitting it an eureka can filled with water, the water displaced will be transferred to a measuring cylinder
Record volume of water in measuring cyclinder, this is the volume of the object
Find the density
