What happens to the particles in matter when hear energy is added to them

Chemistry
1 answer:
Ipatiy [6.2K]4 years ago

There are two possible situations.
1) If a phase change is not occurring, then the heat added contributes to increased translational energy of the particles. What that means is the particles move/vibrate faster.
2) If a phase change is occurring, then the heat added contributes to the breaking of bonds or intermolecular forces (depending on the chemical nature of the matter you're dealing with).

P.1 is a variant of SARS-CoV2. This is the so-called "Brazil variant". It has the amino acid the substitution N501Y in the spike
Free_Kalibri [48]

Answer:

more negative

Explanation:

There are various variants of Coviid virus. The Brazilian variant P also known as Gamma variant is the third variant of the original SARS-CoV2. This variant has raised concerns since it has ability to spread more quickly then previous variants and this is more negative variant. It is assumed that Coviid variant Gamma and Delta has ability to absorb move UV light but this is not proved yet and research is underway.

Answer:

https://youtu.be/3zmeVamEsWI

Explanation:

It is defined as the ratio of moles of one substance to the moles of another substance in a balanced equation. ... Mole ratios are the central step in performing stoichiometry because they allow us to convert moles of one substance to moles of another substance.

Explanation needed please!
VashaNatasha [74]

Answer:

Below

Explanation:

2) there are 28 protons in this isotope

     The number that is on the bottom of the "stacked pair" tells you how many protons are in this isotope. It is often represented by the variable Z.

3) there are 35 neutrons in this isotope

     Subtract the number of protons (28) from the top number

4) there are 28 electrons in the neutral element of Nickel

     If you were to look at the period table and find Ni, you would see that its atomic number is 28. This number tells us the amount of protons and electrons there are in that element.

5) 62.9296694 atomic mass units

     Just search it up (unless your teacher wants you to calculate it)

6) there are 92 protons in this isotope

     Again just look at the Z value to find the proton count

7) there are 146 neutrons in this isotope

     Subtract 238 - 92 = 146

8) there are 92 electrons in the neutral element of uranium

     Again just look at the periodic table and find U

9) 238.0507882 atomic mass units

10) 12C or carbon 12 is more likely to bond with oxygen that 14c carbon 14

     This is because 12C is more abundant at 98.93% than 14C

Hope this helps! Best of luck <3
