1. 2 kcal ( kilogram c ikhalori e ) = ….. c ikhalori e?

Isixazululo

1 kcal = 1000 kcal

2 kcal = 2 (1000 c calorie e ) = 2000 c calorie e

2. 4 C ikhalori e = ….. c ikhalori e?

Isixazululo

I- Calori engu- 1 ( i-Capital C ) = 1 k cal = 1000 calori e

4 C ikhalori e = 4 (1000 c ikhalori e ) = 4000 c ikhalori e

3. 10 c ikhalori e = ….. Joule?

Isixazululo

Ikhalori eli -1 e = 4.186 Joules

Amakhalori angu- 10 c e = 10 (amaJoules angu-4.186) = amaJoules angu-41.86

4. 5 kcal = ….. AmaJoule?

Isixazululo

1 k cal = 1000 c i -alorie = 4186 Joules

5 kcal = 5 (4186 Joules) = 20930 Joules

5. AmaJowule angu-2000 = ….. k cal?

Isixazululo

AmaJowule angu-4186 = 1 kcal

Ama-Joules angu-8372 = 8372 / 4186 = 2 kcal

Ama-Joules angu-2000 = 2000 / 4186 = 0.4777 kcal
