Question

1. What is the relation between the
joule and the kilocalorie?
O 1 kilocalorie = 4.18 < 1010 erg
O 1 kilocalorie = 4.18 x 103 joules
1 kilocalorie = 540 J
O 1 calorie​

Answer 1

Answer:

The relation between Calorie and Joule can be numerically written as-

1 calorie = 4.2 joules

1 Calorie/kcal = 4.2 kilojoules.

Where,

a calorie is the unit of energy.

Calorie or kilocalorie is the unit of energy = 1000 calories.

Joule is the unit of energy

Kilojoule is the unit of energy, = 1000 joules.

Please note that calories and calories are not the same. 1 Calorie = 1000 calories. Sometimes Calorie is often called as kilocalorie. Calorie and calorie both are the units of energy.
