Help me past due Write down what you think will happen to the density of water if you add salt or sugar.
Gennadij [26K]

Answer:

If I add sugar or salt, the water's density will increase.

Explanation:

Density is the relation between mass and volume. We can represent it with the formula δ= m/v. Where δ stans for density, m for mass,  v for volume.

If we add salt or sugar, we increase the mass, but the volume is the same. As a result, the density will increase.

We can use numbers to understand it better.

Suppose that before adding salt or sugar, the mass is 1 g and the volume is 1 l

δ= 1g/l1t

δ= 1 g/lt

Now, if we add sugar or salt, the mass increases. Suppose that we have 2g of mass and the volume is the same, 1l.

δ= 2g/1lt

δ= 2g/lt

We can see that the density increased when the mass increased.
