In the burning food snack lab, a student burned a piece of Cheetos that weighs about 2.4 g. She used 75 g of water that absorbed the heat coming from the burning Cheetos. The initial temperature of the water was
26 °C and it rose to 33 °C. How much heat was released by the Cheetos?
Use the formula: Q= mcAT, where m=mass of water, specific heat of water =1 cal/g. °C, AT=
change in Temperature: final minus initial
