The ratio which denotes the relation between the two different units is said to conversion factors.
According to conversion factors, the relation between calorie and kilojoule is given as, one Calorie is equal to 4.184 kJ.
1 Cal = 4.184 kJ
Now, according to above relation, convert 300 calories into kilojoules.
300 calories =[tex]300 Cal\times \frac{4.184 kJ}{1 Cal}[/tex]
= [tex]1255.2 kJ[/tex]
[tex]\simeq 1255 kJ[/tex]
Thus, kilojoules present in soda is equal to [tex]1255 kJ[/tex]
Answer: 1255.2 kJ
Explanation:.
Energy is the capacity to do work. It is expressed in units like calories, Joules and ergs.
These units of energy are inter convertible.
We are given:
Energy present in soda = 300 cal
Converting this unit of energy into kilojoules
[tex]1 cal=4.184J[/tex]
Thus [tex]300cal=\frac{4.184}{1}\times 300=1255.2kJ[/tex]
Thus, kilojoules present in soda is equal to 1255.2.
