Answer: okay, girl I got you . Chemical.
Nuclear.
Thermal.
Electromagnetic. The Electromagnetic Spectrum. The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. This lesson will introduce electricity as the flow of electrons. In some cases, electricity can be the flow of positive charges or both positive and negative charges. This lesson will focus on the more typically defined flow of electrical current as that of electrons. Students should have some basic knowledge of atoms and their structure. However, as part of their online readings, students will investigate the basics of atomic structure (nucleus, protons, neutrons, electrons). Thus, this lesson provides a good opportunity to clarify misconceptions about atoms and to ensure that all students understand basic atomic structure. According to the Benchmarks for Science Literacy, students of all ages show a wide range of beliefs about the nature and behavior of particles. They lack an appreciation of the very small size of particles; attribute macroscopic properties to particles; believe there must be something in the space between particles; have difficulty in appreciating the intrinsic motion of particles in solids, liquids, and gases; and have problems in conceptualizing forces between particles. This misconception is important to keep in mind when talking about electricity as the flow of electrons. Students may think that the electrons are in the copper wire and not the copper atoms that make up the wire. It is important to stress this point with students so that they develop an understanding that substances are composed of atoms, rather than atoms residing as a separate entity within substances.
Explanation: hope this helped and please mark me brainiest.
Answer:
D) burning a candle
A demonstration that contains both physical and chemical changes will be BURNING OF A CANDLE.
<em>This is because when a candle is lighted up, on the top of it (where we see flame) the oxygen and other gases present around will be chemically changed (burned up)</em>
<em>When the wax in the top of the candle will get melted due to the heat of the fire a physical change takes places.</em>
