A rock has a weight of 5 pounds when attached to a spring scale. When the same rock is placed in the water it has a weight of 2 pounds. What is the name of the force that causes the rock to weigh less when it is placed in the water?
Gravity Force
Density Force
Buoyant Force

equal to 1.3 g/mL
What type of buoyancy does an object have if it sinks in water?
Positive buoyancy
Neutral buoyancy
Negative buoyancy
What type of buoyancy does an object have if it floats in water?
Positive buoyancy
Neutral buoyancy
Negative buoyancy
What type of buoyancy does an object have if it is suspended (does not float or sink) in water?
Positive buoyancy
Neutral buoyancy
Negative buoyancy
The density of a block of aluminum is 2.7g/cm³. If the block of aluminum is heated, what happens to its density? (think about what happens to the molecules when heated...)
Density decreases
Density stays the same
Density increases
The density of a block of aluminum is 2.7g/cm³. If the block of aluminum is heated, what happens to the molecules inside the aluminum?
The molecules move slower and get closer together
The molecules stop moving
The molecules move faster and get farther apart
The density of a block of aluminum is 2.7g/cm³. If the block of aluminum is heated, what happens to its mass and volume?
The mass increases and volume decreases
The mass stays the same and volume increases
The mass decreases and volume increases
