What material is very strong and tough but shows very little elongation as it absorbs energy?
kevlar
Which color reflects heat the most - black or white?
White reflects heat the most because it absorbs very little. Black absorbs a lot of heat, so reflects very little.
What object absorbs most heat and why?
Well, I think metal absorbs the most heat. As, it is the best conductor of heat hope this helps a little! :D
Materials with a high specific heat can absorb a lot of energy and show little change in temperature?
Yes. Specific heat capacity is the amount of heat energy required to change the temperature of the material, so a material with high specific heat needs a lot of heat energy for its temperature to go up.
Why is a sample of radioactive material always a little warmer than its surroundings?
Radioactive material is warmer than the surrounding material because radioactive material is constantly breaking down. When material breaks down, that means that energy is constantly getting released. When energy is released, it produces warmth.

Why can radio telescope can see things that a telescope that detect visible light cant?
-- The source may be one that emits electromagnetic energy in the radio portion of the spectrum but little or no visible light. -- There may be material in the way, such as dust or gas, that absorbs visible light but doesn't absorb radio energy.
A plant that produces too little of the gibberellins might?
Stem elongation will be stunted.
What clour absorbs very little heat radiation?
white

White reflects heat the most because it absorbs very little. Black absorbs a lot of heat, so reflects very little.
What forces responsible for melting sodium chloride?
At high temperature the internal energy of a material is increased; consequently the ionic or molecular ordering is damaged and the material become liquid - a phase with little ordering.

Why does PMMA have a higher UTS and very little elongation compared to polyethylene?
PMMA has bulky sidegroups that hinder intechain movement, thus increasing entanglements
Can someone explain why chemical reactions will either release or absorb energy?
The Law of Conservation of Energy says that the total amount of energy in a system has to remain the same - usually expressed as "energy cannot be created or destroyed". In molecules, the bonds between the atoms have a lot of stored energy in them. In order to break a bond, you have to put in a little energy, but then the energy stored in those bonds is released and available to use. When you run a chemical reaction, you have two steps. First, you have to break the original bonds. This process is exothermic - it releases energy. Second, you have to make new bonds. This process is endothermic - it absorbs energy. What determines whether a reaction absorbs or releases energy is the balance between the two. Hydrogen gas and oxygen gas both contain a lot of energy, while water only contains a little bit of energy. Converting from hydrogen and oxygen to water is exothermic, while converting from water to hydrogen and oxygen is endothermic.

Is pan frying better than deep frying?
A little, but not by much-food just absorbs a little less grease.
