Thermodynamically favored process are those processes that do not require any assistance from outside the system e.g water boils at 25 degrees. Thermodynamically unfavored processes require assistance from outside to induce the required change for example water doesn't freeze at 15 degrees and therefore for that to happen several factors in the system have to be modified to achieve this. Therefore, there is a possibility of companies to produce product by using thermodynamically unfavored process by inducing changes in the system to achieve desired change or modification.
1 would be the 3 one
Hope it’s correct
Due to its higher oxygen content and based on its structure dietheylene glycol has a higher energy efficiency (cal/g) compared to isopropanol and paraffin wax.
<h3>What is the calorific value of a fuel?</h3>
The calorific value of a fuel is the amount of heat energy released from the combustion of the fuel under standard conditions.
Dietheylene glycol, isopropanol and paraffin wax are all used as fuels.
However, due to it higher oxygen content and based on its structure, diethethylene glycol has a higher calorific value than either isopropanol or paraffin wax.
Therefore, dietheylene glycol has a higher energy efficiency (cal/g) compared to isopropanol and paraffin wax.

Answer:
The final temperature of the setup = 36.6°C
Explanation:
Let the final temperature of the setup be T
Heat lost by the copper tubing = Heat gained by water and the vessel
Heat lost by the copper tubing = mC ΔT = 455 × 0.387 × (89.5 - T) = (15759.61 - 176.1T) J
Heat gained by water = mC ΔT = 159 × 4.186 × (T - 22.8) = (665.6T - 15175.1) J
Heat gained by vessel = c ΔT = 10 × (T - 22.8) = (10T - 228) J
Heat lost by the copper tubing = Heat gained by water and the vessel
(15759.61 - 176.1T) = (665.6T - 15175.1) + (10T - 228)
851.7 T = 31162.71
T = 36.6°C
