How much heat is released when 10.0 grams of a substance cools 15 degrees? The specific
heat of the substance is 3.5 J/g °C.

Respuesta :

Answer:

Q = 525 J

Explanation:

Given that,

Mass, m = 10 grams

The change in temperature, [tex]\Delta T=15^{\circ} C[/tex]

The specific heat of the substance is 3.5 J/g °C

We need to find the amount of heat released in the process. It can be given by the formula as follow :

[tex]Q=mc\Delta T\\\\Q=10\ g\times 3.5\ J/g^{\circ} C\times 15^{\circ} C\\Q=525\ J[/tex]

Hence, 525 J of heat is released.
