Question
why do the glaciers not melt completely during summer?
✓
Answer
The latent heat of melting of ice is 80cal. g−1 or 80×4. 2=336J , therefore each 1 gram of ice requires 336J of heat to melt , this much heat is not available to the large mass of ice on glaciers even in summer so ice doesn’t melt completely in summer or winter.
