Answer :
To convert calories into joules, we need to know the conversion factor between these two units. The conversion factor is:
1 calorie = 4.184 joules
To find out how many joules are equivalent to 143 calories, we multiply the number of calories by the conversion factor:
[tex]\[ \text{Energy in joules} = \text{Calories} \times \text{Joules per calorie} \][/tex]
Substitute the given values:
[tex]\[ \text{Energy in joules} = 143 \, \text{calories} \times 4.184 \, \text{joules/calorie} \][/tex]
Now, calculate the product:
[tex]\[ \text{Energy in joules} = 598.312 \, \text{joules} \][/tex]
Therefore, 143 calories are equal to 598.312 joules.
1 calorie = 4.184 joules
