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

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.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
