Answer:
C. Condensation
Explanation:
When molecules release heat energy, it is called exothermic. In this case, condensation would be an example of this.
Answer:
It is the third one
Explanation:
"Both atoms achieve a more stable configuration."
From Q = mcΔT, we can rearrange the equation to solve for mass, m = Q/cΔT. The specific heat capacity, c, of solid gold is 0.129 J/g °C. I'm assuming that the energy is given in joules, as it's not specified in the question as written.
m = Q/cΔT = (35.73 J)/(0.129 J/g °C)(40.85 °C - 0.85°C)
m = 6.92 g of gold was present
