| What us the equation for pressure? | force (N) ---------------- area (m*m) N=Newtons |
| What two things change the pressure on an object: | 1. area 2. force |
| What is homogeneous mixture? | e.g gatorade. Looks the same through out to be homo. *homo = same |
| What heterogeneous? | e.g. fruit salad Loods different with each scoop or though out *hetro = different |
| what is buoyancy? | Whether something floats or not. |
| How do I know if something will be buoyant in water? | 1. Check density of object 2. Compare with density of water (1 g/cm^3) 3. IF LESS than water's density, THEN floats IF MORE than water's density, THEN sinks |
| What is the formula for density? | mass (g) ------------------- volume (cm^3) |
