Answer:
Latent Heat of Vaporization of Nitrogen is 
Explanation:
• We have learned that adding thermal energy by heat increases the temperature of a substance.
• But surprisingly, there are situations where adding energy does not change the temperature of a substance at all. Instead, the additional thermal energy acts to loosen bonds between molecules or atoms and causes a phase change.
• Because this energy enters or leaves a system during a phase change without causing a temperature change in the system, it is known as latent heat (latent means hidden).
• Latent heat of vaporization is a physical property of a substance.
• It is defined as the heat required to change one mole of liquid at its boiling point under standard atmospheric pressure. It is expressed as kg/mol or kJ/kg.
• When a material in liquid state is given energy, it changes its phase from liquid to vapor; the energy absorbed in this process is called heat of vaporization.
• Latent Heat of Vaporization of Nitrogen is
15 number of division on Vernier scale and 12 cm on the main scale means 13.2 cm of the object thickness.
<h3>What is value of 15 division of Vernier scale generally?</h3>
A Vernier scale has 10 divisions and the total length of these 10 divisions is equal to the length of 9 divisions of the main scale that equals to 9 mm so in this way 15 number of division on Vernier scale means 14 divisions on the main scale which is equals to 14 mm and we know that there is 12 cm on the main scale so by adding 12 cm and 14 mm we get the 13.2 cm reading of the object thickness. Vernier caliper is a measuring device that comprise of a main scale and a sliding jaw with an attached Vernier.
So we can conclude that 15 number of division on Vernier scale and 12 cm on the main scale means 13.2 cm of the object thickness.

It can dissolve many substances because 1. Polarity of water molecule. 2. Exceptional hydrogen bonding ability (Not in list)
The volume that sticks out of the water is 83 m³.
To find the answer, we need to know about the archimedes principle.
<h3>What's archimedes principle?</h3>
- It says that when an object is on a water surface, the amount of force on the object is equal to the weight of water displaced by it.
- Mathematically, weight of the object= weight of water displaced
<h3>What's the volume of an object remain on the water surface, if the density and mass of the object are 941.0 kg/m³, 1039.0 kg respectively?</h3>
- Let V = volume of the object,
- v= volume of water displaced
- V-v = volume that sticks out of the water
- Weight of the object = V× density of object × g
- Weight of water displaced= v× density of water × g
- As per archimedes principle, V× density of object × g=v× density of water × g
- V-v = density of water - density of object
= 1024 - 941 = 83 m³
Thus, we can conclude that the volume that sticks out of the water is 83 m³.
