Climates: World, Spain and Europe
Weather and climate are different.
Weather is a short change of the air in an area measured by
temperature, precipitation, humidity, wind, and other factors. Climate is usually defined as the weather conditions in an area over a long period of time.
Physical vs Chemical Changes
Chemical changes make chemical reactions and the creation of new products possible. Typically, a chemical change is irreversible. In contrast, Physical Changes do not form new products and are reversible.
⭐Here are some examples of Chemical Changes:
- The rusting of iron
- Combustion (burning) of wood
- The metabolism of food in the body
- Cooking an egg
- Digesting sugar in saliva
- Baking a cake
- Using a chemical battery
- The explosion of fireworks
- Rotting bananas
- Grilling a hamburger
- Milk going sour
A physical change is a type of change in which the form of matter is altered but one substance is not transformed into another. The size or shape of matter may be changed, but no chemical reaction occurs.
⭐Examples of physical changes include:
- Crumpling a sheet or paper (a good example of a reversible physical change)
- Breaking a pane of glass (the chemical composition of the glass remains the same)
- Freezing water into ice (the chemical formula is not changed)
- Chopping vegetables (cutting separates molecules, but does not alter them)
- Dissolving sugar in water (sugar mixes with water, but the molecules are not changed and may be recovered by boiling off the water)

Matter!
Matter is everything around you. Atoms and molecules are all composed of matter. Matter is anything that has mass and takes up space. It is actually the amount of stuff in an object.
Even though matter can be found all over the Universe, you will only find it in a few forms on Earth. We cover five states of matter here. There are many other states of matter that exist in extreme environments.
Light
Light is a
form of energy which our
sense of sight can detect. It is made of electro-magnetic radiation and
travels in a straight line. Red, green and blue are
the primary colors of light. Mixing them in various ways will make all other
colors, including white.
