Journey Through the States of Matter
Imagine starting your day with a bowl of crunchy cereal. The cereal is a solid, it has a fixed shape that doesn't change. When you pour milk, a liquid, it takes the shape of the bowl. After breakfast, you look outside to see the bright sun. The sun is made of plasma, a state of matter that's like super-heated gas, and not common on Earth. In school, you have a science experiment. You boil water in a kettle and watch as it turns into steam, a gas. This shows how matter can change from one state to another. You also learn about an exciting state of matter called Bose-Einstein condensates, which exist only in extremely cold temperatures! So, in a day, you have experienced different states of matter, and how they can change. Isn't that fascinating?
Question 1
What is the state of matter of the cereal you eat in the morning?
Liquid
Gas
Plasma
Solid
Explanation. Cereal is a solid because it has a fixed shape that doesn't change.
Bose-Einstein condensates
Question 2
What state of matter does milk represent?
Solid
Gas
Plasma
Liquid
Explanation. Milk is a liquid because it takes the shape of its container.
Bose-Einstein condensates
Question 3
What happens to the water when it is heated in a kettle?
It becomes solid
It turns into a plasma
It stays liquid
It turns into gas
Explanation. When water is heated, it turns into steam, which is a gas.
It turns into Bose-Einstein condensates
Question 4
What state of matter is the sun made of?
Solid
