Are there other ways than heat to melt ice?
Answer:
Ice to be stable must be at equilibrium with it's environment.
If the vapor pressure of water is lower than the equilibrium vapor pressure at that temperature, the ice will "melt" directly to vapor. This is called sublimation.
If water can escape into the surrounding medium (say, a salt/water/alcohol solution) more easily than it can escape to the ice, then the mass of the ice will decrease. This is called melting.
Because water expands as it freezes, over a narrow range of temperatures (about 0 to -4 degrees Celsius) water can be melted by applying pressure.
Alcohol works.
Reduce air pressure. Heat is generally easier to come by than a bell jar and vacuum pump.
Pressure.
Urinate on it.
Rock salt.
ice do melt with heat, it melts in winter also. The air also helps melt ice.
however you melt it it will be due to the heat of the item as it will be hotter than the ice so heat from a flame underneath the icecube should be best
salt
salt, water,
doesn't salt melt ice
and that other ice melt stuff that looks like pellets
so I guess both of those are chemical methods
and not heating
You have probably seen salt used during the winter season.Therefore salt can be placed on ice to melt ice. Salt actually lowers the melting point of ice. Also, the chemical calcium chloride can be used.
salt... water..pressure..
ICE:
Most liquids freeze at a higher temperature under pressure because the pressure helps to hold the molecules together. However, the strong hydrogen bonds in water make it different: water freezes at a temperature below 0 °C under a pressure higher than 1 atm. Consequently water also remains frozen at a temperature above 0 °C under a pressure lower than 1 atm. The melting of ice under high pressures is thought to contribute to why glaciers move. Ice formed at high pressure has a different crystal structure and density than ordinary ice. Ice, water, and water vapor can coexist at the triple point, which is 273.16 K at a pressure of 611.73 Pa.
Melting ice by variation in temperature works better as it takes place naturally, while using higher pressure requires application of energy in the form of pressure.
kepp it in hot sun
