Ice melts when exposed to heat because the heat energy causes the water molecules to move faster, breaking the hydrogen bonds between molecules to form liquid water. In the melting process, the water molecules actually absorb energy.
The melting point of ice is 0 degrees Celsius (32 degrees Fahrenheit). This means that ice will melt at this temperature, regardless of how much heat is applied. However, the rate at which ice melts will increase as the temperature increases.
There are a few factors that can affect the rate at which ice melts. These include:
- The surface area of the ice: The more surface area the ice has, the faster it will melt. This is because the heat can more easily reach the ice molecules on the surface.
- The temperature of the surrounding liquid: The warmer the surrounding liquid, the faster the ice will melt. This is because the heat from the liquid can be transferred to the ice.
- The presence of impurities: Impurities in the ice can slow down the melting process. This is because the impurities can interfere with the hydrogen bonds between the water molecules.
So, why does ice melt at a lower temperature? This is because the melting process is endothermic, which means that it absorbs heat. When ice melts, the water molecules are moving faster and the hydrogen bonds between them are broken. This requires energy, which is taken from the surroundin
