Which best describes thermal energy?
A.It is the difference between internal energies of two or more substances.
B.It is the sum of internal energies of two or more substances.
C.It is the portion of internal energy that can be transferred from one substance to another.
D.It is the portion of potential energy that can be transferred from one substance to another.
Answer:
Tha answer I s D. Hope it will work to u
Thermal energy is the difference between internal energies of two or more substances. Therefore, option A is correct.
What is thermal energy ?The energy present in a system that determines its temperature is referred to as thermal energy. Thermal energy flows as heat. Thermodynamics is a whole field of physics that studies how heat is transmitted across various systems and how work is done in the process.
The average kinetic energy of the system's component particles as a result of their motion makes up the thermal energy of the system. The sum of the kinetic and potential energies of the system's component particles represents the system's overall internal energy.
Thermal energy is also referred to as heat energy. A moving object's kinetic energy is its energy. Thermal energy is a type of kinetic energy because it is produced by moving particles.
Thus, option A is correct.

Can someone give me an explanation about the location of the protons, neutrons, electrons in the atom
There are two main areas of an atom, the electron cloud and the nucleus
First, let's talk about the atom's nucleus. The nucleus is in the middle of the atom. The nucleus contains neutrons (particles with no charge) and protons (positively charged protons). The number of protons is constant in every atom of the same element, meanwhile the number of neutrons is not. The atomic number of an element describes the amount of protons in a atom of that same element and it is fixed.
The electron cloud, on the other hand, is a predicted zone that's used to roughly estimate where the electrons are within the atom. Electrons are said to have no fixed orbit.

A solution contains 90 mL of methanol, 18 mL of propanol, and 2 mL of diethyl ether. Which is the solvent in this solution
solution?
O methanol
O propanol
O diethyl ether
O water
Answer:
Methanol
Explanation:
The solvent in this solution is methanol
What is Solvent?Solvent is a substance in which the solute is dissolved.polar and non polar are two types of solvent.
What are Polar solvents and Non Polar solvents?A solvent which has dipole moments are known as polar solvents.A polar solvent can dissolve ions and other polar compounds.A non polar solvent is a solvent which does not have dipole moments.
What is solute?A substance that dissolves in solution is called solute.When two liquids are mixed to form a solution, the solute is the species that is present in the smaller ratio.
Why Methanol is the solvent in this solution?Methanol is the component that has the greatest volume compared to other solvents. It means that it is found in a greater proportion. So methanol is the solvent in this solution.
Hence the other options are incorrect.

If a piece of aluminum has a density of 2.70 g/mL and its mass is 8.1 g. What is its volume?
Answer:
The answer is 3.0 mLExplanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\ [/tex]
From the question
mass of aluminum = 8.1 g
density = 2.7 g/mL
It's volume is
[tex]volume = \frac{8.1}{2.7} \\ [/tex]
We have the final answer as
3.0 mLHope this helps you

How is mass measured? What are standard units used to measure mass?
Answer: Mass in an object is often weighed on a scale. The standard units used to measure mass are the grams (g) and kilogram (kg).
Answer:
The basic SI unit of mass is the kilogram(kg). In physics mass is not the same as weight even though mass is determine by measuring the object's weight using spring scale rather than balance scale comparing it directly with known masses..
If A + B → C + D You start with 50 g of A and 30 g of B and 40 g of C are produced, how many g of D would also be produced?
Answer:40g of D
Explanation:
Law of conservation of matter:
Matter can neither be created nor be destroyed but can change from one form to another.
The total of the reactants must be equal to that of the product.
A+B=>C+D
50g+30=40g+D
80g=40g+D
D=80-40
D=40g

hierve a la misma temperatura un mililitro o un litro de la misma sustancia
Answer:
Yes
Explanation:
Since it is asking you if it boils at the same temperature, not at the same time, instead if it were for the time the answer would be no, because the more substance, the longer it would take to reach the point.
It is true that a millimetre or a liquid of a substance would require same temperature to boil no matter how much amount of that substance you want to boil.
Thus the answer is YES.

Answer:
17 protons
19 neutrons
Explanation:
Chlorine will always have the same amount of protons, and that would be 17 protons.
The atomic mass will change according to how many neutrons are present.
Cl - 35 is comprised of 17 protons and 18 neutrons.
We want to find Cl - 36:
We simply add 1 neutron. 18 + 1 = 19 neutrons.
