Answer: 502.08 J

Explanation:

The heat (thermal energy) needed in to raise the temperature in a process can be found using the following equation:

[tex]Q=m.C.\Delta T[/tex]   (1)

Where:

[tex]Q[/tex] is the heat

[tex]m=8 g[/tex] is the mass of the element (water in this case)

[tex]C[/tex] is the specific heat capacity of the material. In the case of water is [tex]C=4.184\frac{J}{g\°C}[/tex]

[tex]\Delta T=15\°C[/tex] is the variation in temperature  (which is increased in this case)

Knowing this, let's rewrite (1) with these values:

[tex]Q=(8 g)(4.184\frac{J}{g\°C})(15\°C)[/tex]  (2)

Finally:

[tex]Q=502.08 J[/tex]
