Detailed explanation-1: -An ice cube taken from the freezer will rise in temperature, but when it reaches room temperature, it will remain at this temperature. When the ice cube is taken from the freezer, the ice melts by absorbing the heat energy from the surroundings by radiation.
Detailed explanation-2: –When ice is kept at room temperature, it starts melting on its own to form water. Ice has a lower temperature and the surroundings have a higher temperature. So, the system that is, ice starts to absorb heat from the surroundings spontaneously and starts to melt.
Detailed explanation-3: -Solution : Due to increase in temperature ice melts and is converted into water.
Detailed explanation-4: -If ice is heated it changes into water, and this is called melting. If water is cooled below 0°C it freezes to form ice.
