Question

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?

Answer 1

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

Further explanation

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* 4.186* 10\\\\Q=418.6~J`
