In order to make 4 cups of tea, 1.00 kg of water is heated from 22.0 oC to 99.0 oC. How much energy is required? 1) One point for how you would set up the problem and correct answer 2) 1 point for explaining any conversions 3) One point for explaining if this is endothermic or exothermic and why

Explanation:

m = Mass of water = 1 kg

c = Specific heat of water =

= Change in temperature =

Heat or energy required in the system is

The energy required is

Unit of energy is Joule

As heat is being absorbed by the water it is endothermic in nature.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
