A. melting ice is lower temperature than ice-cold water
B. water has higher specific heat than ice
C. ice floats and cools the air above the drink
D. ice absorbs latent heat during melting
E. ice makes better thermal contact than water
Correct Answer:
Option D – ice absorbs latent heat during melting
![Ice of mass 10g at 5ºC was completely converted to water at 0ºC, calculate the quantity of heat used. [specific heat capacity of ice = 2.1 Jg-1K-1, specific latent heat of fusion of ice = 336 Jg‾¹] Ice of mass 10g at 5ºC was completely converted to water at 0ºC, calculate the quantity of heat used. [specific heat capacity of ice = 2.1 Jg-1K-1, specific latent heat of fusion of ice = 336 Jg‾¹]](https://erudites.ng/wp-content/plugins/contextual-related-posts/default.png)
![Calculate the quantity of heat needed to change the temperature of 60g of ice at 0 °C to 80 °C.
