The question states. Peter is heating water on the stove to boil eggs for a picnic. How much heat is required to raise the temperature of his 10.0 kg vat of water from 20.0 degrees celcius too 100 degree celcius. I worked out my problem in this format Delta Q= mass times specific heat times that change in temperature. first i subtracted 100 degree celcius with 20.0 degree celcius and i got 80. idk were to go from here. i am stuck. because i don't have specific heat what am i suppose to do. how am i suppose to know how much heat is requred.
