Answer:
1,632,550
Explanation:
Now, we can calculate the total heat released:
1. Heat released during condensation:
Q_{condensation} = 1 kg x 841000 J/kg= 841000 J
2. Heat released during cooling:
T = 351 K- 30°C= 321 K
Q{cooling} = 1 kg x 2450 J/kg°C x 321 K =791,550 J
Therefore, the total heat released when 1 kg of ethyl alcohol in the gaseous state at 351 K condenses and cools to 30 °C is:
Q = 841000 J + 791550 J = 1,632,550 J
So, 1,632,550 Joules of heat is given off during this process.
