Answer:
Hello!
*I'll include the names here and the definitions and properties in the explanation since they are descriptive.
Three States of Matter:
- Solid
- Liquid
- Gas
Explanation:
Matter:
Anything that has mass and occupies space (volume) is called matter. Basically, matter (and energy) constitute all the phenomena in the universe.
Composition of Matter:
1. Atom:
An atom is the smallest component into which matter can be divided. It contains charged particles such as electrons, protons and neutrons. It is the basic building block of all substances.
2. Element:
An element is a chemical substance that cannot be broken down into its constituents by simple chemical processes. For example, copper (Cu)
3. Compound:
A chemical substance formed by the combination or bonding of two or more atoms or elements. For example, NaCl is a compound that contains the elements sodium and chlorine linked together by chemical bonds.
4. Physical Properties of Matter:
Properties that are physically observable and quantifiable. All properties that can be studied without changing the chemical constitution of matter. Following are some examples of physical properties:
- Melting point
- Boiling point
- Lustre
- Shape
- Conductivity
- Mass
- Volume
- Density
- Length
5. Chemical Properties of Matter:
Properties that demonstrate a substance's ability to form chemical bonds (undergo chemical reactions) with other substances. Chemical properties are only observable or measurable if the state or chemical composition of the substance is changed. Some examples are:
- Chemical stability
- Flammability
- Reactivity (with acids, oxygen, bases, etc.)
- Oxidation/Reduction
- Radioactivity
Answer:
In-spiration Respiration in trees releases energy stored in carbon compounds through a controlled process. Aerobic respiration uses O2 to oxidize organic compounds into CO2 and H2O. Energy released is stored within living cells as ATP, ETM, and a proton bank which are easily used for cell work.
Explanation:
You can put it into ur own words.
By eliminating co2 do you mean respiration?
Answer:
B the mantle becoming more massive and dense due to gravity
Answer:
Geothermal energy
Explanation:
Geothermal energy is the heat that comes from the sub-surface of the earth. It is contained in the rocks and fluids beneath the earth's crust and can be found as far down to the earth's hot molten rock, magma.
