Given that the normal boiling point of CH3COCH3 is 56 °C, which of the following statements about he process below is/are correct? You may choose more than one, or none, of the statements. CH3COCH3(g, 74 °C, 1 atm) → CH3COCH3(1, 46 °C, 1 atm) You may assume that the temperature of the surroundings is constant and also equal to 46 °C. Note: The normal boiling point (Tnbp) is the boiling temperature at 1 atm. The phase change is eversible at the normal boiling point but irreversible if P = 1 atm and T* Tnbp.

States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

the process below is/are correct? You may choose more than one, or none, of the statements.
CH3COCH3(g, 74 °C, 1 atm) → CH3COCH3(1, 46 °C, 1 atm)
You may assume that the temperature of the surroundings is constant and also equal to 46 °C.
Note: The normal boiling point (Tnbp) is the boiling temperature at 1 atm. The phase change is
reversible at the normal boiling point but irreversible if P = 1 atm and T* Tnbp.
The entropy of the system increases: AS > 0.
The entropy of the surroundings increases: ASsurr > 0.
The entropy of the universe increases: ASuniv> 0.
Work is done by the system on the surroundings.
Heat flows from the system into the surroundings.
The entropy change for the system is equal to AH / Tvap.
The entropy change for the system is equal to AHI Tsurr.
The process is thermodynamically reversible.
