Explanation:
Hello again.
So we know the formula
. c is the heat capacity but this time, it is not given. However, water has a very well known heat capacity which is 4.184 J/(g°C). This is in fact the number we refer to a calorie which is the amount of energy you burn that can raise the temperature of 1g of water by 1°C. So, plugging in values, you get the above. But double check if I am wrong.
Electronnegativity increase because the number of charges on the nucleus increases. Which attracts the bonding amount of electrons more.
