Assertion :Latent heat of fusion of ice is 336000Jkg1. Reason: Latent heat refers to change of state without any change in temperature.
  1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
  2. Both Assertion and Reason are correct, but Reason is not the correct explanation for Assertion
  3. Assertion is correct but Reason is incorrect
  4. Assertion is incorrect but Reason is correct

A
Assertion is correct but Reason is incorrect
B
Assertion is incorrect but Reason is correct
C
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
D
Both Assertion and Reason are correct, but Reason is not the correct explanation for Assertion
Solution
Verified by Toppr

The Latent heat of fusion of ice is amount of heat required to convert unit mass of ice at 0oC into water 0oC. For fusion of ice.
L=80calg1=80000calkg1
=80000×4.2Jkg1
=336000Jkg1
Hence both Assertion and Reason are correct but reason is not correct explanation of assertion.
