Question

select all the correct answers.
what happens to water when it changes to ice?

its density increases.

its density decreases.

its mass increases.

its mass decreases.

its volume increases.

its volume decreases.

Explanation:

• Mass is conserved during a physical change (like water freezing to ice). So, the mass of water remains the same when it becomes ice.
• Density formula is \(

ho=\frac{m}{V}\) (where \(
ho\) is density, \( m\) is mass, and \( V\) is volume). When water freezes to ice, its volume \( V\) increases (because ice has an open - lattice structure). Since \( m\) is constant and \( V\) increases, using the density formula \(
ho=\frac{m}{V}\), density \(
ho\) decreases.

Answer:

• B. Its density decreases
• E. Its volume increases
