Car encased in ice texas cracked#
I gently tapped the ice on the roof and trunk with the side of my fist and it cracked and came loose. Even though it was in the low 20s, the sun came out and the thick ice seemed to degrade in the sunlight over the course of the morning (the car being black helped) enough so that I could pry it off the sides in big sheets (I think there was some solar heating going on from the inside as well). De-icing the rest of the car was interesting. The back window took some more work but I got it clear as well. The ice on the front window loosened enough so I could get it off with a scraper. I started the engine and turned on the heater and back window defroster and I let the car run for about 15 minutes. Yesterday I put a small tarp over the driver's door so I was able to get in with little effort. It took me a long time, but I got the ice off the car late this morning. UPDATE: Thanks everyone for the suggestions. This can be quite dangerous as the boiling water may literally explode out of the mug. When you pull the mug of superheated water out of the microwave, the motion you induce in the water in the mug initiates convection and all the water in the mug instantly boils. Thus it's possible to superheat the water in the mug as no heat transfer by convection is occurring within the water in the mug. The microwave energy is transferred directly to the water molecules. You can see a related phenomenon when heating a mug of water in the microwave for tea. Dasani and Aquafina are both bottled water brands that appear to be spring water but are actually demineralized (by reverse osmosis) tap water. If you took a close look at the label on the bottle you would probably find that it's actually demineralized water, not spring water. The water in the bottle is supercooled but remains liquid until you shake the bottle due to the absence of heat transfer by convection and by the absence of nucleation sites (i.e dissolved solids). This ties into Quantum Mechanics, as heat is basically a measure of the speed of atomic motion (This is as simply as I could say it)ĭistilled water would not freeze more quickly from a higher temperature, as it has no particulates to impede heat transfer.Ĭlick to expand.That's a different physical phenomenon. Since the water heater has removed some of the particulates, there is less resistance to heat transfer. These particles fall to the bottom or stick to the anode rod in the water heater.įor matter to change state, not only will it have to have heat added to its change of state temp, but also the latent heat of vaporization (boiling) added for it to change state from liquid to gas (for water this is 2270 kJ/kg.) Freezing is getting the water to the freezing temp (0*C) then also removing the additional heat to overcome the latent heat of fusion. The reason hot water can freeze or boil more rapidly is because some of the obstacles interfering with heat transfer have been removed from the water in the heating process by the heating meduim (in this case the water heater.) Thermodynamics, also a Physics based set of principles, is what is at work here.
