Answer: Option (A) is the correct answer.
Explanation:
When two compounds react together then certain amount of energy must be supplied in order to form new substance. But when heat supplied is less than the heat absorbed by the reactants then there will be very less release of energy.
The reaction between ammonium chloride and water will be as follows.
Therefore, when we dissolve ammonium chloride in to water then ammonium chloride will absorb heat and dissociate into ions and the solution becomes colder. Thus, the reaction will be endothermic in nature because heat is absorbed by the reactants.
Hence, we can conclude that endothermic reaction is occurring when ammonium chloride is dissolved in water.

Answer:
4186 Joules
Explanation:
The specific heat capacity of a substance is defined as the amount of heat needed to raise the temperature of 1 kg of the substance by 1 Kelvin. In formula,
where
Q is the amiunt of heat needed
m = 1 kg is the mass
is the variation of temperature of the substance
For water, the specific heat capacity is . This means that the heat energy required to raise 1 kg of water by 1 K is exactly 4186 J.
Answer:
668 bright fringes
Explanation:
t = Thickness = 0.2 mm
= Wavelength = 600 nm
m = Number of fringes
We have the fringe width relation
So, total number of fringes will be including m = 0 is
