What is the vaporization of bromine?
30.91 kJ/mol
Bromine has a heat of vaporization of 30.91 kJ/mol and its boiling point is 59°C.
What is the condensation point of bromine?
Bromine at 15°C will condense, sublime) when the pressure is raised from 10 to 50 kPa. y gas to liquid þ. Bra at 70 kPa (vaporizes, freezes) when the temperature is decreased from 20 to -15°C.
At what temperature is the vaporization point?
100° C
The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100° C (212° F).
What happens when bromine evaporates?
The reddish-brown liquid evaporates readily into a red vapor with a strong odor resembling chlorine. Bromine is hazardous, according to Lenntech. It is corrosive to human tissue in its liquid state, and it irritates eyes and the throat and is highly toxic when inhaled in a vapor state.
What is the molar enthalpy of vaporization of bromine?
30.71 kJ/mol
The molar enthalpy of vaporization for liquid bromine is 30.71 kJ/mol. Calculate the entropy change in the system, the surroundings, and the universe for the reversible vaporization of 1 mol of liquid bromine (Br2) at its normal boiling point (59°C).
Is Br2 L → Br2 G exothermic?
The Attempt at a Solution The chemical reaction is going from liquid to gas, therefore the entropy is increasing because the reaction is causing more macrostates due to the greater area of distribution for the gas molecules. The reaction is exothermic, because its giving off heat.
What is bromine melting point?
19.04°F (-7.2°C)
Bromine/Melting point

What is the vaporization point of water?
That is, water has a high heat of vaporization, the amount of energy needed to change one gram of a liquid substance to a gas at constant temperature. Water’s heat of vaporization is around 540 cal/g at 100 °C, water’s boiling point.
What is Class 9 boiling point?
Boiling Point: The temperature at which the liquid boils and changes into gaseous state at the atmospheric pressure is called boiling point. For example, water boils at 100°C to form water vapour (at 76 cm pressure).
Is bromine corrosive to metal?
When tested, bromine consistently generates trends of showing higher rates of corrosion when applied to metallic surfaces compared to the rates of other halogens, such as chlorine. Metals that are alloys of iron, aluminium and titanium corrode heavily in the presence of bromine.
What is the enthalpy of formation of liquid Bromine at 25 OC?
The enthalpy of formation for Br (monoatomic gas) is 111.881 kJ/mol.
