Hello,

1. What is buoyancy?

Buoyancy is the ability to float on fluids.

2. What does buoyancy depend on?

Rotaional Stability

3. If the density of an object is less than the desity of water, what will the object do?

It will float

4. The pressure in a fluid is affected by which characteristic of that fluid?

Weight

5. If you heat a container filled with gas what will happen?

It will increase the amount of kinetic enery inside the container and eventually with exer the container.

6. How is pressure measured?

To find  the pressure they sually find the applied force to the liquid.

7. When pressure is applied to an enclosed fluid the pressure is?

It is transmitted equally to each part of the fluid and the containers sides.

8. What is a hydraulic jack example of?

Lifting a heavy load.

9. Decreasing the volume of a plastic bottle increases it's pressure?

Evenly

10. What are gases and liquid categorized as?

States of Matter

11. Air pressure on top of a planes wing decreases?

It will slow down and fall.

12. Fluid drag is a type of___?

Friction or Resistence

13. What does the shape of a particle affect?

Drag

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
