What does it mean for a substance to be soluble in water?

Back

A substance is soluble in water if it can dissolve in water to form a solution. For example, salt and sugar are soluble in water.

What is density?

Back

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

What is the difference between soluble and insoluble substances?

Back

Soluble substances can dissolve in a solvent (like water), while insoluble substances do not dissolve and remain separate.

What is the significance of a material's density in relation to water?

Back

If a material's density is less than that of water (1 g/cm³), it will float; if it is greater, it will sink.

What is a magnet?

Back

A magnet is an object that produces a magnetic field, attracting certain metals like iron, nickel, and cobalt.

What is the role of conductors in electrical energy?

Back

Conductors are materials that allow electricity to flow through them easily. Examples include metals like copper and aluminum.

What does it mean for a substance to be less dense than water?

Back

A substance that is less dense than water will float when placed in water.
