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
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 is chemical added to heat resistant glass?
b
When a chemical is added to a microscope slide with a live paramecium the paramecium moves away from the chemical This movement is an example of?
Negative chemotaxis, which refers to the movement of an organism away from a chemical stimulus. In this case, the paramecium is exhibiting a negative response by moving away from the chemical added to the microscope slide.
What is 31 degrees 64 degrees?
31 degrees and 64 degrees cannot be added together mathematically. If you are referring to a range of temperatures, it would mean the temperature fluctuates between 31 and 64 degrees Fahrenheit or Celsius.
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.

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
How hot can steam get and what factors influence its temperature?
Steam can reach temperatures of up to 100 degrees Celsius (212 degrees Fahrenheit) at sea level. The temperature of steam is influenced by factors such as pressure, volume, and the amount of heat added or removed from the system.
When heat energy is added the speed of the molecules blank?
When heat energy is added, the speed of the molecules increases. This increase in speed leads to a higher kinetic energy and results in a rise in temperature of the substance.
What is the supplement of the complement of a 38 degrees angle?
The supplement of an angle is the angle that, when added to the original angle, equals 180 degrees. The complement of an angle is the angle that, when added to the original angle, equals 90 degrees. Therefore, the supplement of the complement of a 38-degree angle would be the angle that, when added to the complement of 38 degrees (52 degrees), equals 180 degrees. This angle would be 128 degrees.
How many degrees is a triangle supposed to be if you added all the angles?
180 degrees
How many degrees need to be added to a 64 degrees right angle?
26
When bread dough rises when yeast is added is it a chemical change why?
chemical
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
When bread dough rises when yeast is added is it a chemical change?
A chemical change
