For example, to melt ice, you need to add heat energy. To freeze liquid water (to turn it back into ice), you have to remove heat energy.
Yes. For example, if ice is at the melting point (zero degrees Celsius), and you add heat, it will melt, becoming water at zero degrees Celsius. This will continue until you add enough heat energy to melt all the ice. Only then will the temperature start to increase, if you add additional heat.
Melt.
Water doesn't melt, it vaporizes and becomes a gas. The energy from heat melts or vaporizes all matter.
Ice does not melt all at once, and water does not freeze all at once. If you add heat energy to ice, it will melt at 0 oC. If you take away heat energy, water will freeze at 0 oC. The temperature will not change until the phase change is complete, so during the phase change, both liquid water and ice will be present.
It will melt! But you have to add enough energy to equal the latent heat as well as to bring the ice up to the freezing point, if it is in a freezer to start it will be at about -21degC.
The energy required to melt a substance is known as its heat of fusion. For water, the heat of fusion is 334 J/g. Therefore, to melt 18.2g of water, the energy required would be 18.2g x 334 J/g = 6078.8 J.
no it is not it is a physical change because you add heat energy to melt it
The energy required to melt a substance can be calculated using the formula: Energy = mass x heat of fusion. For water, the heat of fusion is 334 J/g. Therefore, the energy required to melt 56g of water would be 56g x 334 J/g = 18,704 J.
The thermal energy of the water increases as it melts, changing from a solid (ice) to liquid water. For a solid to melt, it is necessary for it to absorb energy from its surroundings.
