Question

8. Read the folowing paragraph and
answer the questions.
If heat is exchanged between a hot and
cold object, the temperature of the cold
object goes on increasing due to gain of
energy and the temperature of the hot
object goes on decreasing due to loss of
energy.
The change in temperature continues
till the temperatures of both the objects
attain the same value. In this process, the
cold object gains heat energy and the hot
object loses heat energy. If the system of
both the objects is isolated from the
environment by keeping it inside a heat
resistant box (meaning that the energy
exchange takes place between the two
objects only), then no energy can flow from
inside the box or come into the box.
i. Heat is transferred from where to
where?
ii. Which principle do we learn about
from this process?
iii. How will you state the principle
briefly?
iv. Which property of the substance is
measured using this principle?​

Answer 2

Answer:

(1) Heat is transferred from the object at higher temperature to the object at lower temperature

(ii) We learn the principle of heat exchange from this process

(iii) Principle of heat exchange states that the heat energy lost by hot object is always equal to heat gained by cold object provided that the system of both the objects is isolated

(iv) Specific heat of an object can be measured using this principle.

hope it will help u

thankyou:)
