Answer: Thermal energy is the kinetic energy of particles and heat is the term used to describe how this energy may flow to other systems, such as in a radiator.
Explanation: Molecules have a level of kinetic energy that can be measured by temperature. Higher temperatures result in more rapid and frequent collisons of particles in motion. Heat is the term used to measure the quantity of vibration energy in a given system. The SI unit for heat energy is the Joule. The water molecules in a pot of boiling water have a kinetic energy sufficient for them to break away from other water molecules and become gaseous (boiling point). The heat energy in 1 liter of water at 95C can be calculated in terms of Joules/liter, based on the specific heat of water (e.g., in units of J/gC). This heat can flow to other systems. A home boiler heater unit heats water tha can be pumped around the house ehre it will flow from radiators into thje surrounding air.
Heat is the word used to explain how this energy may transfer to other systems, such as in a radiator, and thermal energy is the kinetic energy of particles.
What is thermal energy?
By virtue of its temperature, a system in a condition of thermodynamic equilibrium has thermal energy or internal energy. Unlike the energy of systems that are not in a state of thermodynamic equilibrium, thermal energy cannot be transformed into meaningful work as quickly.
For instance, the same fluid or solid in a thermodynamic equilibrium state with the same energy (as thermal energy) cannot do work unless it is combined with another substance at a different temperature, as in a heat engine. However, the same fluid or solid in a moving state with the same energy (as mechanical energy) can be converted to work in some mechanical device, such as a windmill or a waterwheel.
Therefore, heat is the word used to explain how this energy may transfer to other systems, such as in a radiator, and thermal energy is the kinetic energy of particles.

Answer: Technically, this cannot be answered, since none of the H atoms have a mass number assigned. With the assumption noted delow, I calculate 1.012 as the average atomic mass.
Explanation:
My answer is based on assumed masses for the three H isotopes:
1H : 1 AMU

Describe the differences between models and scientific laws and theories. (
Answer:
Scientific laws and theories have different jobs to do. A scientific law predicts the results of certain initial conditions. ...

Things around you. All around you there is matter. The chair you are sitting on, air and
water are all matter. Almost everything that you see is matter. Anything that has mass
and takes up space is called matter.
What do we call something that has mass and takes up space?
Answer:
Hi Lovelys!!
Answers down below!!
Explanation:
There are two answer my me: Matter and Volume
Matter is anything that has mass and takes up space. Mass gives an object the property of weight and inertia (resistance to change in the motion of an object).
Volume simply refers to the space an object takes up. Depending on the physical state of an object, there are a couple ways to measure volume. If we are trying to measure the volume of a box, for instance, we would multiply the length of the box by its height and by its width.

Which benzene derivative would be the least reactive in an electrophilic aromatic substitution reaction
Assuming equimolar quantities of reactants, which compound will react to the greatest extent with boron trifluoride (BF3) in a Lewis acid-base reaction
To solve such this we must know the concept of acid-base reaction. Therefore, NH[tex]_3[/tex] is the compound that will react to the greatest extent with boron trifluoride (BF[tex]_3[/tex]) in a Lewis acid-base reaction.
What is chemical reaction?Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
NH[tex]_3[/tex] is an example of a Lewis Base that will react extensively with BF[tex]_3[/tex] to form the compound NH[tex]_3[/tex] + BF[tex]_3[/tex] → [B (NH[tex]_3[/tex])F[tex]_3[/tex]].

PLEASE HELP!!!!!!!!! WILL MARK BRAINLIEST
Answer:
19.278049929737628457607385688801
Explanation:
Volume = L * W * H
Volume = 17.78 * 9.21 * 4.45 = 728.70441
Density = Mass / Volume
Mass = 14,048
14,048 / 728.70441 = 19.278049929737628457607385688801
Density = 19.278049929737628457607385688801
Explanation:
So density = mass/volume
Using this formula we'll solve the question.
mass = 14,048g/1000 = 14.048 kg
volume = 17.78/100 x 9.21/100 x 4.45/100
volume = 0.3143 m³
density = 14.048 kg/ 0.3143 m³
density = 44.69 kg/m³
round off to = 44.7 kg/m³

h = 3.0 a + 28.2
A pediatrician uses the model above to estimate the height h of a girl, in inches, in terms of the girl's age a, in years. Based on the model, what is the estimated height of a 2-year-old girl?
Answer:
h = 34.2 in
Explanation:
h = 3.0a + 28.2
h = height of a girl.
a = age of a girl.
h = 3.0a + 28.2
h = 3.0(2) + 28.2
h = 6 + 28.2
h = 34.2
The estimated height of a 2-year-old girl is 34.2 in.

Answer:
lost 2 electrons
Explanation:
A cation by definition is a positively charged ion. They are formed when a metal loses its electrons. A cation has more protons than electrons, giving it a net positive charge. So, it had to have lost 2 electrons to give it a positive charge of 2⁺.
