Question

As water is cooled from 4°C to 0° C, its density

O
A. decreases and increases
O
B. increases
O
C. decreases
O
D. stays the same

Answer 1

Option B - Density increases

Step-by-step explanation:

Density is defined as:

δ = mass / volume

When T°2 is > T°1, volume has been increased

As the volume increased, density has decreased.

↓δ = mass / volume ↑

In the situation above, temperature decreased from 4° to 0°.

The volume has been reduced, so the density has been increased.

↑ δ = mass / volume ↓
