What is matter?
Matter can be defined as anything that has mass and can occupy space.
Thus, any physical object or substance that is found on planet Earth is typically composed of matter.
The three (3) states of matter:
Since all matter are made up of atoms, they have a property of existing in three (3) distinct states and these include;
SolidGasLiquidA bulk property of matter refers to the property that affects matter as a whole and they are listed as follows:
1. Stress
2. Strain
3. Elasticity
4. Boiling point
5. Surface tension
6. Vapor pressure
In conclusion, the other list of properties are not a bulk property of matter.

Relate: What are three ways to organize data?
Explain: What should scientists do if their hypothesis is supported?
Consider: How does the process of inquiry usually begin?
Recognize: What happens if a hypothesis is not supported?
Answer:
When gathering data, whether qualitative or quantitative, we can use several tools, such as: surveys, focus groups, interviews, and questionnaires. To help organize data, we can use charts and graphs to help visualize what's going on, such as bar graphs, frequency charts, picture graphs, and line graphs.
If your hypothesis is supported, you might think of ways to refine your hypothesis and test those. Either way, the process of experimentation often leads to whole new questions to explore. The possibilities are infinite, and the search for knowledge is never-ending.
The scientific method is a process that helps answer questions based on observations, carefully planned experiments and deductive reasoning. All scientific inquiry begins with the identification of a problem or question to be answered based on observation.
If the initial hypothesis is not supported, you can go back to the drawing board and hypothesize a new answer to the question and a new way to test it. ... Either way, the process of experimentation often leads to whole new questions to explore. The possibilities are infinite, and the search for knowledge is never-ending.

1. what is the energy associated with electromagnetic radiation of 6.34 x 10^15 hertz
2. What is the frequency of one of the bands of the sodium emission spectrum that has a wavelength of 585 nanometers?
1. The energy associated with an electromagnetic radiation of [tex]6.34 \times 10^{15} \;Hertz[/tex] is equal to [tex]4.2 \times 10^{-18}\;Joules[/tex].
2. The frequency of one of the bands of the sodium emission spectrum is [tex]5.13 \times 10^{14}\;Hertz[/tex]
Given the following data:
Frequency = [tex]6.34 \times 10^{15} \;Hertz[/tex]Wavelength = 585 nm to m = [tex]5.85 \times 10^{-7}\;meters[/tex]Scientific data:
Speed of light = [tex]3 \times 10^8\;meters[/tex]Planck constant = [tex]6.626 \times 10^{-34}\;J.s[/tex]1. To determine the energy associated with an electromagnetic radiation of [tex]6.34 \times 10^{15} \;Hertz[/tex], we would apply Einstein's equation for photon energy:
Mathematically, Einstein's equation for photon energy is given by the formula:
[tex]E =hf[/tex]
Where:
E is the energy.h is Planck constant.f is photon frequency.Substituting the given parameters into the formula, we have;
[tex]E = 6.626 \times 10^{-34}\times 6.34 \times 10^{15} \\\\E = 4.2 \times 10^{-18}\;Joules[/tex]
2. To determine the frequency of one of the bands of the sodium emission spectrum:
Mathematically, the frequency of a wave is given by the formula:
[tex]Frequency = \frac{Speed}{wavelength} \\\\Frequency = \frac{3 \times 10^8}{5.85 \times 10^{-7}} \\\\Frequency =5.13 \times 10^{14}\;Hertz[/tex]

Astronomers often scan the sky using devices called radio
telescopes. What can you conclude about these devices?
Answer:
A radio telescope is simply a telescope that is designed to receive radio waves from space.
radio telescopes helps to study naturally occurring radio light from stars, galaxies, black holes, and other astronomical objects. We can also use them to transmit and reflect radio light off of planetary bodies in our solar system.

The specific heat capacity of liquid water is 4.18 J/g-K. How many joules of heat are needed to raise the temperature of 5.00 g of water from 22.0 °C to 57.0 °C?
Answer:
731.5j.
Explanation:
Basic Formula : Q = mcT.
Q - Heat gained or lost.
m - mass of the given substance.
c - specific heat capacity.
T - Change in temperature ( it often has a delta(triangle) before it.
so now we are directly asked to find the heat.
Q = mcT
m= 5g
c = 4.18
but T = 35k which means 35 kelvin.
why? because you will need to convert the two given initial and final temperatures inorder to cancel the unit kelvin out from the formula above. the target is simply to make the unit J - joule be left alone.
now We convert celsius temperature to kelvin by adding a constant of 273.15 approximately 273.
therefore - Tk = Tc + 273
which will be equivalent to 295k for the initial temperature and 330k for the final.
now granted...keep in mind to use the CHANGE in temperature which is the difference of the 2 kelvin temperatures we just converted
so T = 330k - 295k = 35k
then just substitute everything in the very 1st formula i stated above.
Q = mcT = 5 x 4.18 x 35 = 731.5 J
peace to you.

representative element or a transition metal

Answer:
The correct answer is a transition metal.
Explanation:
Hope it helps.
Comments:
Hearts and RatesMark me as Brainliest AnswerFollow MeAll the given elements are representative elements as they have valence electrons present in p -orbital except option a which has valence electron d-orbital and hence is not a representative element.
It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.
Thus, all the given elements are representative elements as they have valence electrons present in p -orbital except option a which has valence electron d-orbital and hence is not a representative element.

a positively or negatively charged particle is called:
Answer:
A positively or negatively charged particle is called an ion.
