How much energy is required to raise temperature of 1gm of water by 1c

Answer 1

Hey friend,

Here's your answer,


✔ One calorie is the amount of heat required to raise the temperature of 1g of water by 1°Celsius.


________________________________




✴ Since, we know, that heat is a form of energy, it can also be expressed in Joules.



☸ Joule is the SI unit of energy.



✒ The relation between Joules and other units of heat ( Calorie and kilo calorie) are :-


✴ 1 calorie = 4.2 Joules

✴ 1 Kilocalorie = 4200 Joules

✴ 1 Joules = 0.24 calorie


Therefore, it can also be said that, 4.2 Joules of energy is required to raise the temperature of 1 gm of water by 1°C.




Hope this helps!!!
