Explain why standard units of measurement are particularly important to scientists.

Answers

Answer 1
Answer:

The standard units of measurement are particularly important to scientists because they make the result more accurate and precise.

What are accuracy and precision?

When the average value of the different measurements is similar to the correct value then the measurement is said to be accurate and the phenomenon is said to be accurate.

When the values of measurement are close to each other then the result is said to be precise and the phenomena are said to be precise and need to do for the better accuracy of results.

Therefore, they make the result more accurate and precise.The standard units of measurement are particularly important to scientists.

Answer:

Explanation: The standred units of measurments are important to scientists because they are the same measurments that all scientist take to make sure that they all have the correct results.

Explain difference in appearance between a pure substance and a mixture.

Answers

A pure substance is a substance which cannot be separated physically or chemically. It is the same wherever found on earth. For example, pure gold is a pure substance. It will be the same whether it is found where you live or on another country. A mixture can be either homogeneous or heterogeneous. A homogeneous mixture is a mixture that looks the same throughout but is made of more than one element. An example of this would be salt and water mixture.  A heterogeneous mixture is a mixture in which you can easily identify the different parts which make it up. An example of this would be pizza. Both these mixtures can be broken into different parts either physically or chemically.

Hope it helps :)
a pure substance means its like a natural substance that has not been tampered with, such as sodium. but when sodium is mixed with chlorine it becomes sodium chloride( table salt), which is a mixture.

Multiply 3.2 mm times 5 mm and express the answer to the correct number of significant figures.​

Answers

Answer:

\large \boxed{\text{ 20 mm}^(2)}

Explanation:

In multiplication  and division problems, your answer can have no more significant figures than the number with the fewest significant figures.

\text{3.2 mm} * \text{5 mm} = \text{16 mm}^(2)

There are two significant figures in 3.2 and one in 5.

\text{You must round to one significant figure and report the answer as $\large \boxed{\textbf{ 20 mm}^{\mathbf{2}}}$}

What two factors affect the boiling point of water? A. Temperature and mass
B. Temperature and volume
C. Pressure and volume
D. Pressure and temperature

Answers

Answer:

D.  Pressure and temperature.

Explanation:

The answer is D because when water molecules (H2o) have heat and pressure added it will boil.  For exampe if your cooking pasta, you add water to your pan and when you add heat and put the lid of the pan it will boil.
