QuestionHow many calories are in $6.55 \mathrm{~kJ}$ of energy? Convert to calories: [?] cal.

Studdy Solution

STEP 1

Assumptions1. The energy absorbed by water is6.55 kJ. We know the conversion factor from kilojoules to calories1 kJ =239.006 cal

STEP 2

We need to convert the energy absorbed by water from kilojoules to calories. We can do this using the conversion factor.
$Energy\, in\, calories = Energy\, in\, kJ \\times Conversion\, factor$

STEP 3

Now, plug in the given values for the energy in kJ and the conversion factor to calculate the energy in calories.
$Energy\, in\, calories =6.55\, kJ \\times239.006\, cal/kJ$

STEP 4

Calculate the energy absorbed in calories.
$Energy\, in\, calories =6.55\, kJ \\times239.006\, cal/kJ =156.2893\, cal$ The water absorbs approximately156.29 calories of energy.
