At one spot on venus, the second closest planet to the sun, the surface temperature was 726 k. convert this temperature to °c and °f.

-  452.85 degree C and 847.13 degree F.

Solution:- The given temperature is 726 K and it asks to convert it to degree C and degree F. For degree C to K conversion we add 273.15. So, if we are doing opposite conversion that is K to degree C then we need to subtract 273.15.

degree C = 726 - 273.15 = 452.85

Now we could convert degree C to degree F using the formula:

Let's plug in the value of degree C temperature in it:

= 815.13 + 32

= 847.13 degree F

So, 726 K would be 452.85 degree C and 847.13 degree F.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
