Question

Assertion: Temperature near the sea coasts is moderate
Reason: the angular momentum of the earth moon system is not conserved.
a) If both assertion and reason are true and reason is the correct explanation of assertion.
b) If the assertion and reason are true but reason is not the correct explanation of assertion.
c) If the assertion is true but reason is false.
d) If both assertion and reason are false.

Answer 1

in this question we will see the basic phenomena taking place at the sea coast for the given assertion. This will give us the required answer. Further we will discuss the basics of temperature. We will also see the basics of a thermometer, as it is used to know the temperature, for our better understanding.

Complete step-by-step answer:
Here, water has higher heat capacity than soil and rock. So, the sea takes much longer to get heat and cool than the land. Also, water has high thermal conductivity.
As we know that the temperature near seacoast is moderate because thermal conduction never takes place at sea-cost causing moderate temperature.
Therefore, the correct option is b) i.e., the assertion and the given reason both are true but reason is not the correct explanation of assertion.

So, the correct answer is “Option b)”.

Additional Information: As we know that the temperature is defined as the quantity measured by any thermometer. Also, here temperature is related to the average kinetic energy of atoms and molecules in a given system. When we know about the term absolute zero, it is the temperature at which there is no molecular motion in the given system. Further, we know that there are three main temperature scales that are: Celsius, Fahrenheit, and Kelvin.
Also, a thermometer is a device that measures temperature or temperature gradient. A thermometer has two important elements that are:
A temperature sensor- bulb of mercury-in-glass thermometer acts as a temperature sensor; in this some changes occur with a change in temperature.
Some means of converting this change into a numerical this change into a numerical value.
A clinical thermometer is a small medical thermometer with a short but finely calibrated range. These are used by doctors in clinics. A clinical mercury thermometer has mercury in them which expands with the temperature.

Note: We should remember that the thermal conductivity of a material is defined as the measure of its ability to conduct heat..There are different types of thermometer present for different purposes, like- clinical thermometer; laboratory thermometer etc. thermometers have different limits. The S.I unit of temperature is Kelvin (K).
