All plastics are polymers (but not the other way around). There are a zillion different plastics, and a wide range of melting temperatures for them. Some don't melt, but actually suffer decomposition at higher temperatures because their molecular structure won't permit them to melt. Unfortunately, the question is so broad that not much more can be said except to give some examples of common plastics:
No, MDMA does not melt. It is a solid crystal at room temperature.
Ice will melt faster in a room temperature glass compared to a frozen glass. The room temperature glass provides a warmer environment for the ice to melt quicker, while the frozen glass will keep the ice colder for longer, slowing down the melting process.
yes, frozen desserts have a melting point like anything else. If the temperature exceeds that, the dessert will melt.
The temperature rose above freezing, causing the snow to finally begin to melt.
Natural driving force causing ice to melt spontaneously at room temperature is the atmospheric pressure of nature.That and the fact that room temperature is well above freezing , one can put all the pressure one wants on ice , but until it rises above 0 deg. C , it will not melt. So temperature is the main factor , not pressure.
It does melt.
Yes you can melt it. But you want a high temperature.
i believe its thesame as your body temperature that's why it melt in your mouth and pocket
Ice will melt at a temperature of 0 degrees Celsius or 32 degrees Fahrenheit.
Increasing the melt temperature the material can be transformed in a gas.
Skin does melt at the temperature of 200 degrease C.
No, MDMA does not melt. It is a solid crystal at room temperature.
ice can melt at room temperature. Anything that is liquid at room temperature would, in its frozen state, melt at room temperature. Oils, beverages and mercury - if in a frozen state - would melt when exposed to room temperature.
They melt because the heat in the air is warmer than the temperature of the ice cubes.
sodium chloride
160°
melting temperature is when something melt in that time what is the temperature of it.
