How fast ice melts depends on the temperature it is exposed to and what substance it is in. Ice melts at different speeds depending on if it is in air or water.
Ice generally melts quicker when it is in water, assuming they are at the same temperature. This is because water molecules are more dense; this means that more water comes into contact with the surface of the ice. Secondly, water has a higher capacity for heat. However, if the air is moving quickly across the surface of ice, then the molecules have more chances to interact with the surface and may be able to melt the ice quicker.Learn More
Wind increases the rate of evaporation by removing air already laden with water vapor from above the water. The rate of evaporation depends, in part, on the existing level of water vapor in the surrounding air, since water vapor condenses at the same time as water evaporates in normal circumstances. Strong winds also move the water, expanding the amount of surface area available for evaporation.Full Answer >
The brand of kettle is needed to determine the exact amount of electricity used, but most kettles have an average wattage of 2 or 3 kilowatts or kW. If a 2 kW kettle is used for 2 hours then it has used 4 kWh.Full Answer >
Water is a liquid at room temperature because the hydrogen bonds within its construction are weak. These weak bonds hold water molecules together for mere milliseconds, which keeps water in a constantly liquid state at room temperature.Full Answer >
