Mixtures. How do you make hot chocolate? Read and think. One, read and answer. A, what is a pure 00:00:00
substance? B, what is a mixture? C, what is filtration? D, what is a homogeneous mixture? 00:00:10
A pure substance consists of only one component. For example, silver, water, salt, and wood are 00:00:20
pure substances. A mixture happens when we put two or more substances together. For example, 00:00:29
we can mix a yogurt with sugar. There are two types of mixtures, heterogeneous mixtures and 00:00:37
homogeneous mixtures. Heterogeneous mixtures. In a heterogeneous mixture, we put two or more 00:00:45
substances together, but we can still see them separately. The whole mixture looks different. 00:00:53
For example, when we make fruit salad, we can make a heterogeneous mixture. We can still see the 00:00:59
different fruit separately. Homogeneous mixtures. In a homogeneous mixture, we put two substances or 00:01:05
more together, but we can't see each of them separately. The whole mixture looks the same. 00:01:13
For example, when we put sugar and orange juice and stir, we make a homogeneous mixture. We can't 00:01:20
see the sugar and the orange juice separately anymore. It just all blends. Separating mixtures. 00:01:26
There are different ways of separating mixtures. Two common methods are evaporation and filtration. 00:01:34
Evaporation separates homogeneous mixtures, for example, salt and water. Leave the mixture in a 00:01:42
shallow dish. So that means a dish that is not very deep. So let's say this was the dish, 00:01:49
It's not very deep. It's shallow. 00:01:54
So we put the mixture in, the water evaporates, and the salt stays in the dish, right? 00:01:57
So the salt reappears separately. 00:02:05
Filtration. Filtration separates heterogeneous mixtures. 00:02:08
For example, sand and water. 00:02:12
Pour the mixture into a filter. 00:02:15
The water passes through the filter. 00:02:17
The sand stays in the filter, right? 00:02:19
because the sand doesn't dissolve into the water. 00:02:22
