No. Mixtures always have lowered melting points.

Is glass melting a chemical change?
I believe melting most items is a physical change as you are only changing the state of the matter, not it's composition. There may however be a breakdown that occurs depending on the composition of the glass with high enough temperatures. This would change the chemical composition. I believe you can relate it to melting plastic (don't actually do this as it releases toxic gases). At low enough temperatures it just becomes soft and moldable. At higher temperatures you burn it down and cause changes in the material. I'm no expert
When salt is added to boiling water at 100 degrees Celsius will the water boil faster or slower?
Slower, at higher temperature that is.
What boils at 96.2 degrees Celsius?
Water boils at 104 degrees celsius, I think.
Which component is affected when a catalyst is added to a chemical reaction?
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.
What do acids increase the number of when added to a chemical?
H+
As heat is added to a solid substance the atoms do what and move apart?
The higher the temperatures, the faster the atoms move. If the temperatures are high enough, the atoms may move apart changing the state of the object.
How can convert centigrade to Fahrenheit?
Zero degrees Celsius is equal to 32 degrees Fahrenheit. Go any higher than the 1.8 degrees Celsius to 32 degrees is added. Each down 1.8 degrees from 32 degrees Celsius which is low.

What are two factors that are affected when an enzyme is added to a chemical reaction?
- with enzymes the rate of reaction is higher- an important characteristic of an enzyme is the specifity

Can fren be added to the air conditioner unit at the house at any exterior temperature?
No, Freon can only be added of the outdoor temperature has been between 45 and 95 degrees for at least 48 hours. Otherwise, it wil end up being to much or too little freon when temperatures normalize
Does rusting happen faster if at a higher temperature and if so why?
Rusting is a chemical reaction between iron and oxygen. Specifically, it is the oxidation of iron. Almost chemical reactions occur at a faster rate at higher temperatures because particles have more kinetic energy. Based on the principle that particles must collide to react -----> This increase in kinetic energy means that when particles collide they 1) collide with more energy and 2) have more frequent collisions therefore the rate of reaction increases. The exceptions are exothermic reactions, which tend to slow down when more heat is added.
