MCQ
One calorie is equal to
  • A
    $0.4184 $ $Joule$
  • ✓
    $4.184$ $Joule$
  • C
    $41.84 $ $Joule$
  • D
    $418.4$  $Joule$
✓

Answer

Correct option: B.
$4.184$ $Joule$
b
We need to find $1$ calorie is equal to how many joules.

A calorie is the amount of energy that is supplied in the nutrients that make up food. Because it is a form of energy, calories can be converted to joules through a measurement of heat.

$1$ calorie $=4.186$ joules. is the required answer.
