When an atom loses one or more electrons to form a positive ion the energy is?
Energy is released and absorbed
Is more energy absorbed than released is the result of an endothermic chemical reaction?
In an endothermic reaction, heat is taken in from the environment. Heat is a form of energy. Therefore, energy is taken in, i.e. absorbed.
Why absorption rate of galactose is more than glucose?
it is absorbed by active transport
Which statement describes how the absorption of solar energy by the Earth's surface changes during an ice age?
During an ice age, the Earth's surface is covered by a larger area of ice and snow. This increased ice and snow cover increases the Earth's albedo, or reflectivity, causing more solar energy to be reflected back into space rather than being absorbed by the surface. As a result, the absorption of solar energy by the Earth's surface decreases during an ice age.
Advantage of having a long small intestine?
There will be more absorption of nutrients

When iodine goes from iodine to iodine gas in energy absorbed or released?
Energy is absorbed because the iodine is going from a liquid to a gas. This means that the iodine molecules are moving faster so they had to have absorbed more energy to do this.

What has got more or less energy between endothermic and exothermic?
Any substance when undergoes a phase change heat is either absorbed or released The reaction in which heat is absorbed known as an endothermic reaction and in which the heat energy is released, is known as exothermic reaction. DKK
Is more energy from the sun absorbed or reflected by Earth's surface?
Absorbed
What does nuetron absorption accomplish in a nuclear reactor?
Neutron absorption is the key to the operation of a nuclear reactor as this is what perpetuates the chain reaction. Neutrons can be absorbed by a number of things within the core of an operating reactor, but when a fuel atom absorbs a neutron, it becomes unstable and fissions. The fission event releases fission fragments, energy, and more neutrons, which will, when absorbed, continue the chain reaction.

What converts light from the sun into thermal energy and distributes the heat using pumps and fans?
Sunlight reaching the earth along various electromagnetic wavelengths is converted to different wavelengths by refraction as it passes through or is absorbed by different materials when it reaches the Earth. Some of these different wavelengths are absorbed into materials as heat and some are reflected away producing no heat, but providing visible colors, or as invisible (to us) EM energy. Resistance always produces heat, absorption of EM energy, or reflection of that energy is a function of resistance of an object to the passage of the wave energy. The greater the resistance the more opaque the object appears, and the more energy is absorbed as heat.
What is the separation process which works because some colours are absorbed more easily by paper than others?
selective absorption
How do you know if the heat is absorbed or released?
Boiling does require the liquid to be absorbing heat--large amounts at the point of transition from liquid to gas. Obviously, in the real world, some of this heat is being released simultaneously, but more must be absorbed than is released for boiling to continue.
What is neutron absorption?
Neutron absorption is the process wherein an atomic nucleus will absorb a neutron. Many different atomic nuclei will do this, and different nuclei will present a larger of smaller target for the neutron, as you might have guessed. This is the neutron absorption cross section for the material, and it varies as the material does and as the kinetic energy of the neutron does, as well. You may have figured out that there are many different resulting products or outcomes that can be seen from neutron absorption. It is neutron absorption that powers up a chain reaction, so let's look at that aspect of this phenomenon. In a nuclear reactor, some spontaneous fissions will release neutrons, and these neutrons will, if the control rods are pulled out sufficiently, begin a chain reaction. The nuclear fuel, usually either uranium or plutonium, will absorb a neutron (after some slowing down of that neutron), and they'll fission as a result. These fissions will release more neutrons, which will be absorbed and will create more fissions, which will release more neutrons, etc. A neutron released from a fission event will have a high kinetic energy; it will be moving very quickly. It might be absorbed, but will have a higher probability of being absorbed if it is slowed down, or thermalized. The moderator in a reactor, usually water, does this slowing down of the neutrons. The slower neutrons have a much higher probability of being absorbed and continuing the chain. Fission by neutron absorption is the mechanism by which a nuclear chain reaction is maintained in a nuclear reactor.
