If a tensile force is suddenly removed from a wire then its temperature will
1 decrease
2 increase
3 become zero
4 remains constant
Explanation:
Sudden removal of tensile force on the wire, increases the kinetic energy of its molecules. Hence temperature of the wire increases. So correct option is (2)

Assertion : Water can be made to boil without heating. Reason : Boiling point is lowered by increasing pressure.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
To boil water without heating it, we need to decrease the external pressure until the vapor pressure of the liquid equals the atmospheric pressure. So correct option is (3).
