What will happen if you didn't have chemical energy in your body

You wish to cook some pasta and so take some water and heat it on a stove. If you use 2000 grams of water with an initial temperature of zero degrees C, how much energy would you need to add to raise the temperature to 100° C is all of the stove

A spring is 14cm long. Three masses are hung from it and then it is measured again. Now it is 19.5cm long. What force did the three masses provide? The spring constant for the spring is 30N/m.
