Answer :
80 calories are required to melt 1 gram of ice. (The energy required to elevate one gram of water by one degree Celsius is one calorie.) - The solidification process is what turns liquid into ice. 80 calories per gram will be released throughout this procedure.
What is the underlying concept here?
This issue is meant to provide you an estimate of the amount of heat required per gram of solid water, or ice, in order for a solid to liquid phase change to occur. Simply put, a measurement of the amount of heat needed to melt one kilogram of ice at its typical melting point of 0 degrees Celsius is provided. Therefore, you could conclude that 80cal/g is similar to 80cal of It took 0C of heat to turn 1 g of ice from a solid to a liquid. Thus, 3 g of ice would require 3 g x 8 cal / 1 g / 240 cal. So, keep in mind this notation. 80cal per gram. g1means that by applying 80cal of heat, every 1 g of ice at 0°C can be transformed into liquid water at 0°C.
