Water (3070 g ) is heated until it just begins to boil. if the water absorbs 5.03×105 j of heat in the process, what was the initial temperature of the water?

Explanation:

The heat absorbed is given by:

 (1)  

Where:  

 is the mass of water

 is the specific heat of  water  

 is the variation in temperature, being  the final temperature which is the boiling temperature of water  

is the initial temperature

Finding :

  (2)  

  (3)  

 (4)  

Knowing  and we can find :

(5)

(6)

Finally:

This is the initial temperature of the water
