g a 144 g metal bar requires 2500 J to change its temperature from 23.5 to 100 degree C what is the specific heat of the metal

226.9 J·kg⁻¹·°C⁻¹

Explanation:

The specific heat of a substance can be defined as the amount is heat that has to be added in order for a given mass of the substance to increase its temperature:

In this case:

We input the data:

And calculate c:

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
