A student wants to know the number of food Calories in their favorite snack. They burn their snack under a can of water to measure the energy transfer and record the following information: Mass of water: 200g Water temperature before burning (Ti): 25oC. Water temperature after burning (Tf): 45oC. The Specific Heat (Cp) of water is 1 chemistry calorie/g oC Calculate the number of chemistry calories of Heat transferred to water using the following formula: Q= M * Cp * (Tf -Ti)

Question
5) A student wants to know the number of food Calories in their favorite snack. They burn their snack under a can of water to measure the energy transfer and record the following information:
Mass of water: 200g
Water temperature before burning (Ti): 25oC.
Water temperature after burning (Tf): 45oC.
The Specific Heat (Cp) of water is 1 chemistry calorie/g oC
- Calculate the number of chemistry calories of Heat transferred to water using the following formula:
Q= M * Cp * (Tf -Ti)
- The mass of the snack before burning was 2.0g and the mass after the snack burning was 1.0g. Calculate the number of chemistry calories per gram of the snack.
