Question

As temperature increases from $0^{\circ }Cto{4}^{\circ }C$ the density of water ______

Answer 1

1. As temperature increases from $0^{\circ }Cto{4}^{\circ }C$ , water changes from a solid to a liquid state.
   Thus, as temperature increases volume of water increases.
2. We know that, $density=\frac{mass}{volume}$
3. Therefore, we can see that, as volume increases, density will decrease.
4. Hence, as temperature increases from $0^{\circ }Cto{4}^{\circ }C$ the density of water decreases.
