Question

A 0.37 g Cheeto is burned and the heat produced is used to heat 50 grams of water from 22.1 degrees * C to 34.4 degrees * O . What is the energy value of the Cheeto in kcal / g ?

Expert Solution

Step 1

Mass of Cheeto=0.37 g

Mass of water=50 g

Initial temperature =22.1°C

Final temperature=34.4°C

Temperature change, $∆ T$ =34.4-22.1=12.3°C

Specific heat of the water in kCal= 1 cal/g°C

The energy value of the Cheeto in kcal/g=?
