How much energy, in joules, is released when 17 kilograms of granite is cooled from 45 c to 21 c? a. 365,575.3 j b. 785,662.8 j c. 901,980.3 j d. 327,992.8 j

Answer is: D. 327,992.8 J.
m(granite) = 17 kg = 17000g.
ΔT(granite) = 21°C - 45°C = -24°C (-24K).
cp(granite) = 0,804 J/g·°C, specific heat capacity of granite.
Q = m(granite) · ΔT(granite) · cp(granite).
Q = 17000 g ·(-24°C)· 0,804 J/g·K.
Q = -327990 J.
The granite lost 327990 joules of energy.
Q - amount of energy gained or lost. 

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.

Theoretical temperature at which molecules stop moving and no more heat can be removed from the object. kelvin: absolute zero degrees. none of the above.
