Yes
There is really no set time on how long pottery need in the kiln. You just it to be at a certain temperature to get the effect like having it on low temperature to melt your glaze and some has to be on high to melt.
yes, temperature does effect plastic if it gets to hot it can melt it.
melting temperature is when something melt in that time what is the temperature of it.
Depends on the temperature.
a low temperature will freeze the substance, a high temperature will melt or turn the substance into vapor
The effect of salt (any soluble material will work) is to lower the freezing point of the water, making it melt faster at a given temperature (or melt at all, if the temperature is slightly below the normal freezing point).
I assume you mean "iceberg". If they are large, they will take a long time to melt, since they can only melt at their surface.The time it takes them to melt will also depend on the temperature - as well as the shape of the iceberg.
depends on the ambient temperature
Not as long as the air temperature remains below freezing.
The answer depends on the temperature of the water.
Yes. When a candle is in cold temperatures, it tends to melt much slower than a candle burning in room temperature.
No. A gross example is Venus, which has a runaway greenhouse effect. The surface temperature is hot enough to melt lead.
