Assertion Reason on Heat
Questions:
Q.1. Assertion (A): All materials conduct the heat.
Reason (R): Conductors are the materials which allow heat to pass through them easily.
(a) Both assertion (A) and reason (R) are true and (R) is correct explanation of assertion (A).
(b) Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A).
(c) Assertion (A) is true, but reason (R) is false.
(d) Assertion (A) is false, but reason (R) is true.
Difficulty Level: Easy
Ans. Option (d) is correct.
Explanation: All materials do not conduct the heat. Based on ability to conduct the heat materials are classified as: Conductors and Insulators. Conductors are the materials which allow heat to pass through them easily. For examples, aluminium, iron and copper. Insulators are materials which do not allow heat to pass through them easily. They are poor conductors of heat. For example, plastic and wood.
Q.2. Assertion (A): The body temperature of every person is not 370C
Reason (R): It is an average temperature of human body.
(a) Both assertion (A) and reason (R) are true and (R) is correct explanation of assertion (A).
(b) Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A).
