PRE-LAB QUESTIONS:

What is the difference between “scientist calories” and “nutritionist calories”?

A food label reads “80 Calories (C)”. How many “scientist calories” are in the food?

3. If burning a peanut caused 20.0 g of water to increase by 50.0 °C, what is the number of dietary

calories (Cal)?

Table 1:

Trial 1

Trial 2

Trial 3

Mass of peanut before ignition

Mass of peanut after ignition

Mass of peanut converted to energy

Volume of water

Mass of water

Initial temperature of water

°C

Final temperature of water

°C

Change in temperature of water

°C

Calculations:

1. Calculate the amount of heat absorbed by the water in the can (the amount of heat given off by the

peanut) in calories. !" !"#$% =!1.00 cal/g°C

!(!"#$%&) = !(!"#$%)×!"(!"#$%)×(!

− !

)

!"#$%

!"!#$%

2. Remember 1000 calories = 1 kcal = 1 Calorie. How many food Calories were given off by the peanut
