Question: Explain how each of the three types of energy transfer occurs in a solar oven while it cooks a bowl of soup.
Read below for some ideas of the answer and if you answer please make your answer reasonable.
To remove a metal pan from a hot oven, you must use an insulated pad or glove. If you do not, energy will transfer quickly to your hand by conduction. The pan is much hotter than your skin, so its particles have a lot more thermal energy. When the particles of the metal bump into the particles of your skin, energy is transferred.
When the hot pan is on top of the stove, you can tell that it is hot by holding your hand above the pan. The moving air around the pan absorbs energy and carries it to your skin by convection. You can also absorb energy by holding your hand to the side of a stove’s heating element. Energy is transferred through radiation to your skin.
Energy in the form of heat can be transferred by conduction, convection, and radiation. During all three types of energy transfer, the thermal energy of the warmer object decreases and the thermal energy of the cooler object increases. In all three types of energy transfer, energy is being transferred to a cooler object.

Answer:
Converting light energy to heat energy: Solar cookers concentrate sunlight onto a receiver such as a cooking pan. The interaction between the light energy and the receiver material converts light to heat and this is called conduction. This conversion is maximized by using materials that conduct and retain heat.
Explanation:
Solar cookers focus sunlight onto a recipient, like a cooking pan, to convert light energy into thermal energy.
What is energy?Energy is the ability to perform work in physics. It could exist in several different forms, such as potential, kinetic, electrical, chemical, thermal, electrical, radioactive, etc. Additionally, there is heat and work, which is energy being transferred from one body towards another. Energy is always assigned based on its nature once it has been transmitted.
Motion is a property of all energy types. For instance, if a body is moving, it possesses kinetic energy. Even while at rest, a tensioned object like a spring or bow has the ability to move; this is because of its design, which includes potential energy. Solar cookers focus sunlight onto a recipient, like a cooking pan, to convert light energy into thermal energy. Conduction is the process by which light energy is transformed into heat by interacting with the receiver material. Utilising heat-conducting and heat-retaining materials will maximise this conversion.
Therefore, Solar cookers focus sunlight onto a recipient, like a cooking pan, to convert light energy into thermal energy.

In 4 Ar2CO3 - 8 Ar atoms, 4 C atoms, 12 O atoms
Explanation:
All you need to do is multiply the coefficient by the number of each atom in the compound. For example, H3NCH3Br has 1 nitrogen, 1 carbon, 1 bromine, and 6 hydrogens. If you have 2H3NCH3Br, just multiply all those numbers by 2.

The octet rule states that atoms will gain, lose, or share valence electrons to get a full outer shell (orbital). Explain in your own words why this is an important rule to determine types of chemical bonds
someone pls help me i need it by today ty :)
Answers
Answer:
In covalent bonding, the octet rule is important because sharing electrons gives both atoms a full valence shell. As a result, each atom can consider the shared electrons to be part of its own valence shell.

In covalent bonding, the octet rule is important because sharing electrons gives both atoms a full valence shell.
What are chemical bonds?A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds.
The octet rule states that atoms are at their most stable when they have the electron configuration of a noble gas.
This means having eight outer shell electrons. Because of this, atoms tend to try and gain or lose electrons until they have eight electrons in their outer shell.
As a result, each atom can consider the shared electrons to be part of its own valence shell.

heat is added as a solid turns into a gas.
Answers
When heat is removed as a gas turns into a liquid. In liquid state molecules are more closer than in gases. Hence, option a is correct.
What is a phase change ?The interconversion between states of matter is called phase change. The conversion of solid to liquid, liquid to gas, etc. are examples of phase changes.
In solid state, particles are closely packed and cannot move apart. The strong intermolecular forces can be weaken by applying energy. In liquid state, particles have some more space to low and in gases they are far apart.
When gases phase converts to liquid, the heat is removed from the system and make make the intermolecular forces stronger to bring molecules closer.

Answers
Answer:
animals unlike us adapt faster to heat/cool weather or water
Explanation: Let's use fish as an example because that's the main water pet, so when you get a new fish and you have to put it in the water for about let's say 15 minutes. It's so it can adapt to the water. Water for us needs to be hot enough for us to actually feel the heat so therefore animals can adapt not only faster to heat but to cool air/water a lot faster than we can. I don't know if this helps or makes sense but it's what I know and have seen :P
