Fredrick has two samples of pure water - sample X and sample Y. Sample X has a volume of 1 L and sample Y has a volume of 10 L. How do the boiling points of these two samples compare?
Group of answer choices
Sample X will boil at a lower temperature because it has less volume.
Sample Y will boil at a lower temperature because it has more volume.
Which ever sample receives heat first will have a lower boiling point.
Sample X and Y will boil at the same temperature.
Answer:
D. Sample X and Y will boil at the same temperature
Explanation:
The boiling point of a liquid is the temperature at which the vapor pressure equals the atmospheric pressure.
The boiling implies a phase change of water from liquid to vapor. This requires an input of energy in the form of heat. Since Y has a greater volume than X, Y will require a higher heat input. However, the boiling temperature will remain unchanged.

What are the steps to evaporate Copper sulfate crystals?
Answer:
copper sulfate is soluble in water its crystals dissolve in water to form copper sulfate solution. During evaporation, the water evaporates away leaving solid copper sulfate crystals behind. A solution is placed in an evaporating basin and heated with a Bunsen burner

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.

How many atoms of each element are chemical formula: 3K2O3.
How many atoms of each element are chemical formula: 2H3NCH3Br.
How many atoms of each element are chemical formula: 4Ar2CO3.
Each of them are different questions pls help me!!! I need to get this right to bring my grade up from a C to an A!!!
Answer:
In 3K2O3 - 6 K atoms, 9 O atoms
In 2H3NCH3Br - 12 H atoms, 2 N atoms, 2 C atoms, 2 Br atoms
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.
