Question

please help me... Q: What is the difference between the Scientist/Engineer'scalorie and the dietician's Calorie? The energy released when afood sample is burned(in a calorimeter) is determined by measuringthe mass of water and the increase in the temperature of the water.A chem. 1414 student named C.T. Garcia decided to carry out theexperiment in order to confirm the Calorie claim on the label(120Calories or two cracker sheets). For this, she took twosheets(31.6g) and burned the in calorimeter that contained3500 g of water and the temperature of the water rose by 34.4C. Wasthe claim on the label justified? [Specific heat of water = 1cal/g C] show work... please help me... Q: What is the difference between the Scientist/Engineer'scalorie and the dietician's Calorie?

Explanation / Answer

The scientist's or engineer's calorie is the unit of energywhich is equal to 4.184 Joules exactly. ( 1 cal)
