Water has a specific heat of 4.186 J/g*C. How much energy would be required to raise the temperature of 10 g of water by 10 C?
Sladkaya [172]

Energy(heat) required to raise the temperature of water : 418.6 J

<h3>Further explanation  </h3>

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

Specific heat of water = 4.186 J/g*C.

∆T(raise the temperature) : 10° C  

mass = 10 g

Heat required :

\tt Q=m.c.\Delta T\\\\Q=10\times 4.186\times 10\\\\Q=418.6~J
