Question

pre-lab:
what is the formula that is used to calculate the amount of heat absorbed or released by water during a temperature change?
q= mhf

the conversion factor for calories to joules is 4180 joules = 1 food calorie. calculate how many food calories are equivalent to 20,000 joules of heat energy.

using the nutritional information of the pringles chips, determine the amount of food calories in 1 pringles chip
26 chips have 270 calories. one chip has 9.6 calories.
then, multiply that number by 4180 to find your accepted joules for 1 chip.

Explanation:

Step1: Set up conversion ratio

Use given 1 Food Calorie = 4180 Joules

Step2: Calculate Food Calories

$\text{Food Calories} = \frac{20000}{4180}$

Answer:

$\approx 4.78$ Food Calories
