<u>Answer:</u>
<em>
needed to heat the amount of water giving.
</em>
<u>Explanation:</u>
To solve this question we first need to know the specific heat of water which is given by <em>4.18 joules</em> Per gram for increasing <em>1° of temperature</em>. Now since one gram of water name one joules per gram so 2 grams will need <em>twice of 4.18</em> that is 8.36 similarly 50 grams will need ![50 \times 4.18 = 209](https://tex.z-dn.net/?f=50%20%5Ctimes%204.18%20%3D%20209)
Now we need to calculate the heat for 10° of change because temperature rises from 50° centigrade to 60° centigrade and difference in degrees
<em>so heat needed is=
</em>
It’s D actually because a proton has a positive charge and an electron has a negative charge
