Unit 15 - Laboratory Work

 

Bu ünitede de Bilim ve Teknoloji derslerinde karşılaştığımız ingilizce tabirlerden bahsedeceğiz.

madde        matter
katı        solid
sıvı        liquid
gaz  gas

 

There are three states for matters, they are "solid state, liquid state and gas state"

 

 

Solids have shapes. We can hold solids in out hands.
Liquids and gases don't have certain shapes. They take the shape of their containers.
For example, if you put water in a glass, the water takes the shape of the glass.

 
This desk is solid. A pencil is solid. A pen is solid too. But the ink in your pen is not solid. It is in liquid state.
 
An orange is solid but orange juice is liquid.
 
Can we see gases? Usually, they are invisible but sometimes we can see them. We can see smoke, can't we? We can see the exhaust fumes of a truck too.

 

If you put a glass of water in the refrigerator, it will freeze.
If you heat ice, it melts.
If you heat water too much, it boils.

 

Burada kullandığımız "if" sözcüğü, "eğer" manasına gelir.
 
-What happenes if you heat water to fifty-five degrees? Does it boil? Or does it freeze?
-No, It doesn't boil or freeze.
 
-What happenes if you heat water to 100 degrees?
