First you need to convert kiloJoules to Joules
1 kJ is 1000 J
1500kJ *1000J == 1500000 J
Then 1500000J * 1Cal/4.18 J == 358851.6746 calories
1 kJ is 1000 J
1500kJ *1000J == 1500000 J
Then 1500000J * 1Cal/4.18 J == 358851.6746 calories
Answer : The heat energy in calorie is [tex]3.59\times 10^5\text{ Calorie}[/tex]
Explanation :
As we are given the conversion for heat energy.
[tex]1\text{ Calorie}=4.18\text{ Joules}[/tex]
or,
[tex]1\text{ Joules}=\frac{1}{4.18}\text{ Calorie}[/tex]
As we are given that:
Heat energy in kJ = 1500 kJ = 1500000 J
conversion used : (1 kJ = 1000 J)
Now we have to determine the heat energy in calorie.
As, [tex]1\text{ Joules}=\frac{1}{4.18}\text{ Calorie}[/tex]
So, [tex]1500000\text{ Joules}=\frac{1500000\text{ Joules}}{4.18\text{ Joules}}\text{ Calorie}=3.59\times 10^5\text{ Calorie}[/tex]
Therefore, the heat energy in calorie is [tex]3.59\times 10^5\text{ Calorie}[/tex]
