How much heat is required to raise the temperature of 100 grams of water from, 25c to 82 c?

- 23.8 kJ of heat is required to raise the temperature of water.

Solution:- We have been given with grams of water, it's initial and final temperature and asked to calculate the heat required to raise it's temperature. Here, lower degree C water is changing into higher degree C water. So, the formula used to calculate the heat is:

Where, q is the heat energy, m is mass, c is specific heat of water and delta T is change in temperature.

m = 100 grams

= 82 - 25 = 57 degree C

q=?

Let's plug in the values in the formula and do the calculations:

q = 23848.8 J or 23.8 kJ

So, 23.8 kJ of heat is required to raise the temperature of 100 g of water from 25 to 82 degree C.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
