What happens when a cork and a rock are placed in water?

Back

The cork floats while the rock sinks, indicating that the rock is more dense than both the cork and the water.

Front

What is density?

Back

Density is the mass of an object divided by its volume. It determines whether an object will float or sink in a fluid.

Front

What is an example of a homogeneous mixture?

Back

Lemonade is an example of a homogeneous mixture because the components are evenly distributed and cannot be easily separated.

Front

What is an example of a heterogeneous mixture?

Back

Trail mix is an example of a heterogeneous mixture because the different components can be seen and separated.

Front

What happens when oil and water are mixed?

Back

Oil and water do not mix because oil is less dense than water, causing the oil to float on top.

Front

What is the principle of buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which depends on the object's density compared to the fluid's density.

Front

What is the difference between a solution and a mixture?

Back

A solution is a homogeneous mixture where one substance is dissolved in another, while a mixture can be heterogeneous and retains the properties of its components.

Front

What is an example of a physical change?

Back

Melting ice is an example of a physical change because it changes from solid to liquid without altering its chemical composition.
