What doesn't melt ice?
colder temperatures then what the ice is, a working freezer
Does Ice melt at different rates in different liquids?
The only factors that lead ice to melt areheat transferthermal conductivityand the mixing of saltwater solution into newly-melted iceOther factors such as viscosity of liquids do not alter the speed in which a certain mass of ice melt.
What is TPE plastic?
TPE stands for Thermo Plastic Elastomer. It is a range of polymers (plastics) that can be processed (moulded or extruded) like a plastic when over their melt temperature, but exhibit properties of thermoset rubber. the advantage to using TPE over thermoset rubber, is that it can be easily re-moulded and re-worked whereas rubber cannot. TPE can be soft, stretchy, and flexible, or hard and rigid depending on the mixture of crystalline and amorphous polymers used.
How can you quickly melt two inch thick ice in -20 Celsius temperatures?
To melt it quickly add calcium chloride or ferous chloride, either will work down to -55 Celcius. You will need 43 grams per 100 g of ice for the CaCl2 and 50g / 100g if using feCl3 How quickly it melts will depend on how much mixing you do after adding the salt.
Can uranium melt?
Any element can melt.
What happens during hot melt extrusion when manufacturing drugs?
During hot melt extrusion, the active pharmaceutical ingredient and the polymers are heated about their class Tg or Tm. Screws are then fed into them for mixing purposes. If then quickly cools to form a glass.
What is the difference between melt spinning and dry spinning?
Melt spinning is used for polymers that can be melted i.e. the polymers must have a melting temperature (thermoplastic polymers). Dry spinning is used for polymers that do no have melting temperature and need to be dissolved in solvent (thermoset polymers). In case of melt spinning, the polymer solidifies by cooling after being extruded from the spinneret. Whereas, in case of dry spinning, the polymer solidifies through evaporation of solvents and this is achieved by a stream of air or inert gas.
Definition of melting method?
it is something that you melt
What is the definition of the word melt?
to become liquefied by warmth
What is the definition for the root word fusio?
The root word "fusio" is derived from the Latin word "fundere," meaning "to pour" or "to melt." It is commonly used in English to denote a blending or mixing together of different elements, as seen in words such as fusion, confuse, and diffuse.
Define what temperature index is related to polymers?
The value of Tg depends heavily on the mobility of the polymer chain, and for most synthetic polymers lies between 170°K and 500°K (-103°C and 227°C). Pure crystalline polymers do not have a glass transition temperature because the glass transition temperature is only applicable to amorphous polymers.
What doesn't melt ice?

Why does vegetable oil melt ice?
Mixing almost any substance with water will lower its freezing point. When you mix vegetable oil with ice, the long molecules disrupt the ice crystals forming, thus lowering the freezing point and cause it to melt.
Does Ice melt at different rates in different liquids?

Does polythene melt when heated?
Because, it has no crosslinks therefore its molecules move more freely. On the other hand, some other polymers, such as Bakelite, are crosslinked and you cannot turn then into a liquid without breaking the covalent bond.
When volcano works?
Trust me, You'll know when a volcano is working as soon as your cloths start to melt to your skin.
Can metamorphic rock melt to form sedimentary rock?
No. If a rock melts and then re-solidifies, then by definition the resulting rock is igneous.
