Two ways in which physical state of matter can be changed:
- changing the temperature
- changing the pressure
They are alike because #1 they are a change insubstance, #2 the form is different. I hope i have been a huge help to people who need this for homework!
What exactly is matter? Matter is anything that has mass and takes up space. There are two main ways of classifying matter. Matter is classified first by its physical state as a solid, liquid, or gas. Secondly, we classify matter by it chemical constitution as an element, a compound, or a mixture. We are going to learn about the differences between atoms, ions, and molecules, the differences between compounds, elements, and mixtures, and the difference between physical and chemical changes.
Both chemically, and physically. First of all, if the mixture contains solids, many instruments could be used, such as a sieve or a magnet. If they were chemical, you could heat them, or freeze them, or use other methods for chemical reatctions, to separate the mixtures
what are three ways that people have changed the land in our country
Physical and Chemical
A rotten fruit is a physical change. Physical changes involve a change in size shape or state but the chemical makeup of the material remains the same. In the case of a rotten fruit the physical appearance has changed but the chemical composition of the fruit remains the same. The physical change can be seen in the following ways: The color of the fruit has changed from its original color to a brown or black color. The texture of the fruit has changed from firm to mushy. The smell of the fruit has changed from sweet to sour.Rotten fruit is an example of a physical change because the chemical composition of the fruit remains the same even though the physical appearance has changed.

1) physical erosion. 2) chemical weathering.

If you add heat to matter, it can either get it hotter, or it can change the state of matter (for example, from solid to liquid).

Colourless is a property, or word to describe matter, however the "gas" would be something you're describing. However, if a reaction is omitting a colourless gas, it could be considered a physical property of the reaction.
Changes of pressure or temperature
this is considered to be a hard question to answer. I'm sorry.
in what ways has drama changed over the past centuries
The two types of changes in matter that it goes through is physical change and chemical change... trust me, we are learning this at school.
