What are eV?
What are eV and when do we use them? I know they are a unit of energy and are called electron volts, but how do we convert to joules?

Re: What are eV?
The conversion factor from eV to joules is given on the constants and equations worksheet (1 eV = 1.602 x 10^-19 J), so I do not believe you need to memorize this.

Re: What are eV?
1 eV= 1.602 x 10^-19 J (this conversion is on our equation sheet). I believe a question will specify whether to give your answer in eV or J.

Re: What are eV?
Hi,
eV are electron volts and the conversion factor to get to joules is for every 1 eV you have 1.60218x10^-19 joules. You will only need to use this if you are asked for the answer in this unit or need to get to joules.

Re: What are eV?
To convert eV to joules you use this simple conversion factor:
1 eV = 1.602x10^-19 J
1 eV = 1.602x10^-19 J

Re: What are eV?
The conversion from eV to J is: 1 eV = 1.602x10^-19 J. It is also given on our equation sheet!

Re: What are eV?
I am also wondering when we use eV? Like for what concepts? However, I do understand that the conversion is on the equation sheet.

Re: What are eV?
I don’t believe EVs are used specifically for any concepts. They are simply another form of measuring energy. It’s like the difference between nano meters and normal meters. We simply use on or another if the problem asks for it.

Re: What are eV?
Everybody's already answered the conversion, but to answer what an electron volt really is, it's the kinetic energy of an electron as it accelerates under some specific conditions. It's like just a characteristic of an electron and that's why it keeps showing up when we work with energy problems.

Re: What are eV?
eV stands electron volts, and 1 eV = 1.602x10^(-19) juoles. They are used when it's a concept involving measuring energy.

Re: What are eV?
eV are electron volts and the conversion factor is 1 eV = 1.602x10^-19 J
It is also the kinetic energy acquired from an electron or proton that is acted upon by a potential difference of 1 volt.

eV are electron volts and to convert eV to joules it is 1 eV= 1.602x10^-19 J. This is found on the equation sheet.

Re: What are eV?
The question will usually specify when we need to use or convert from or to eV. We have the conversion for eV in our equation sheet as eV = 1.602x10^-19.

Re: What are eV?
eV is another way of expressing Joules and the conversion factor is 1 eV= 1.602 x 10^-19 J. You can find it on the equation sheet; however, most of the time you will work with joules and possibly convert the final answer to eVs.

Re: What are eV?
Hello! The conversion is 1.602 × 10^-19 J. You can use this number easily to convert eV to Joules and vice versa. It's just like converting moles to grams, if that helps give you a way to think about it! Hope this helps!

Re: What are eV?
eV, or Electron Volt, is a unit of energy. 1 eV is equal to 1.6x10^-19J. This number, 1.6x10^-19, is precisely the amount of charge in Coulombs in one electron. This is because eV is defined as the amount of kinetic energy produced when an electron passes through one volt of potential difference. I hope this help!
