an ice cream has marked a value of 700Kcal. How many kilowatt hour of energy will it delivered to the body as it is digested
Verified answer
Answer:
[tex]\bigstar[/tex] Given:
⇒ An ice cream has marked a value of 700Kcal
[tex]\bigstar[/tex] To Find:
⇒ How many kilowatt hour of energy will it delivered to the body as it is digested (in KWh)
[tex]\bigstar[/tex] Solution:
[tex]\rm 1 kcal = 10^3cal=1000cal = 4200 J[/tex]
[tex]\blue{\boxed{\boxed{\rm 1kcal = \dfrac{4200}{3.6*10^6}\; \;KWh }}}[/tex]
[tex]\sf Therefore,\; for\; 700kcal[/tex]
[tex]\implies \rm 700kcal = \dfrac{700*4200}{3.6*10^6}\; \;KWh[/tex]
[tex]\sf On \;further \;Simplification \; we \;get\;,[/tex]
[tex]\rm \implies 0.81KWh[/tex]
[tex]\orange{\boxed{\boxed{\sf{0.81KWh}}}}[/tex]
0.81 KWh
Explanation:
Given:
Value of Ice Cream = 700Kcal
To Find:
The kilowatt hour of energy will it delivered to the body as it is digested.
Solving:
=> 1 kcal
=> [tex]10^{3}[/tex] cal
=> 1000 cal
=> 4200 Joules
Formula Used For Finding 1 kcal:
1 kcal = [tex]\frac{4200}{3.6*10^{6} }[/tex] KWh
In the question we are given 700 kcal:
Finding For 700 kcal:
= 700 kcal = [tex]\frac{700*4200}{3.6*10^{6} }[/tex] KWh
Solving Further:
= 0.81 KWh
Therefore, 0.81 Kilowatt Hour of energy will be delivered to its body as it is digested.
