Matter
What is matter
Matter is any substance that has mass and takes up space by having volume.
What are the 2 measurement types.
qualitative, and quantitative
the 6 types of scientific notation are.
Who is John Dalton
was an English chemist, physicist, and meteorologist, best known for introducing the atomic theory into chemistry.
What are the 3 different states of matter
solid, liquid, and gas
What is the difference between qualitative, and quantitative.
Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings.
Why do you need to publish your results
Publishing results of research projects in peer-reviewed journals enables the scientific and medical community to evaluate the findings themselves. It also provides instructions so that other researchers can repeat the experiment or build on it to verify and confirm the results.
How did Rutherford discover the nucleus
Rutherford discovered the dense atomic nucleus by bombarding a thin gold sheet with the alpha particles emitted by radium From this observation, they concluded that almost all the atomic matter was concentrated in a tiny volume situated at the atom center, the atomic nucleus.
What is a physical change
A physical change in matter is a change in one or more of matter's physical properties. In a physical change, matter may change its size, shape, or state, but its chemical properties do not change.
What is scientific notation, and what does the coefficient have to do with it.
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. The coefficient must be greater than or equal to one and less than 10
Why is the scientific method important
The scientific method attempts to minimize the influence of bias or prejudice in the experimenter. It provides an objective, standardized approach to conducting experiments and, in doing so, improves their results.
What is a sigfig
Significant figures of a number in positional notation are digits in the number that are reliable and absolutely necessary to indicate the quantity of something.
What are mixtures of matter
Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.
how do you convert in scientific notation.
To convert any number into scientific notation, you write the non-zero digits, placing a decimal after the first non-zero digit. Then, you count the number of digits you need to move the beginning decimal to get to where your decimal is now. If you move the decimal to the left, then your power is positive.
How has the scientific method helped the humans find answers to problems in our world.
The Scientific Method helps you put together experiments, use data to find conclusions and interpret them. In short, the Scientific Method is a step-by-step process.
What is the atomic mass of carbon
12.0107
Explain phase changes.
A phase change is when matter changes to from one state (solid, liquid, gas, plasma) to another. These changes occur when sufficient energy is supplied to the system (or a sufficient amount is lost), and also occur when the pressure on the system is changed.
What is a unit conversion
Conversion of units is the conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors.
