Question

When 20 grams of water is heated from 10 c to 15 c, the required energy in joule is
​

Answer 1

418.6 J

Step-by-step explanation:

We know the specific heat for water is 4.186 kJ/kg * °C, so this can also write as 4.186 J/g * °C, so the heat increases 5 C in this question, so you can get 4.186(J/g * C) * 5C * 20g = 418.6 J
