When water evaporates, its latent heat of evaporation absorbs heat.
<h3>What is Latent heat?</h3>
A body or thermodynamic system can release or absorb latent heat during a constant-temperature process, often a first-order phase transition.
There are two types of latent heat:
- The heat of freezing
- The heat of vaporization
The statements about water's latent heat and changes in state are:
- The heat of freezing is the quantity of thermal energy produced as a liquid freezes, and the heat of vaporization is the quantity of thermal energy needed to change a liquid into a gas.
- Water may move energy from one location to other thanks to latent heat.
- There aren't any weak (hydrogen) bonds between water molecules in the vapor state.
- Hurricanes are propelled by the latent heat of condensation, which occurs when water vapor condenses and turns into a liquid.
- All water molecules in the solid state are connected by flimsy (hydrogen) bonds.

Answer: Option (c) is the correct answer.
Explanation:
When current passes through a wire then a magnetic field is formed. Therefore, when two wires carry current in the same direction then both the wires with have respective magnetic fields in the same direction and their total magnetic field will be large.
But when current between two wires flow in opposite direction then the magnetic field produced will also be in opposite direction. Therefore, both the magnetic fields cancel each other out. Thus, total magnetic field will be small.
As a result, wires which carry current in the opposite direction repel each other.
If the system is cooled, more of the products will be formed as the equilibrium shifts to the right.
Explanation:
The reaction is an endothermic reaction which absorbs heat from the environment. This is why we see energy on the reactant side.
This reaction is in equilibrium when energy is absorbed in this manner.
According to Le Chatelier's principle "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
- A change in temperature of an equilibrium system shifts the system to a new equilibrium point.
- The backward reaction is favored by an increase in temperature because heat is absorbed in that step.
- This will eventually lead to the production of more of the product.
- Cooling the system will decrease the temperature and will favor the forward reaction.
- If the system is cooled, more of the products will be formed as the equilibrium shifts to the right.
- More NO gas will be produced in the process.

The phenomenon that best explains the miscibility of heptane in pentane is that both are non-polar compounds.
<h3>Solubility of compounds</h3>
Solubility is defined as the ability of a solute or substance to dissolve in a given solvent and at a particular temperature.
Heptane is a straight-chain alkane hydrocarbon that contains 7 carbon atoms. It is a non polar solvent.
Pentane is also a straight-chain alkane hydrocarbon that contains 5 carbon atoms. It is also a non- polar solvent.
Both pentane and heptane are non-polar because the atoms in their molecules share electrons equally. They are able to dissolve each other because they are alike.
