What is cephalic phase?
This phase is when the Brain prepares to absorb food, and the saliva production increases
When radiation is absorbed by an object its temperature increases or decreases?
When radiation is absorbed by an object, its temperature typically increases. The absorbed radiation is converted into heat energy, causing the temperature of the object to rise. However, certain materials may exhibit behaviors like selective emission in which they release more energy than they absorb, resulting in a decrease in temperature.
Why does a baby's weight go down after birth then increases?
absorb the body fluid and new environment.
What are the two functions of the colon?
1. absorb water and salt 2. hold resulting waste
Does liquid give off or absorb energy when it turns to gas?
Liquids absorb energy to turn into a gas. The resulting temperature should be less than the initial temperature.
What is the cephalic phase?
This phase is when the Brain prepares to absorb food, and the saliva production increases
Why do dark surfaces absorb heat?
Dark surfaces absorb heat because they absorb a wider range of light wavelengths, converting them into thermal energy. This is due to their ability to absorb more photons from sunlight, which increases their temperature. Lighter surfaces, on the other hand, reflect more light and therefore do not absorb as much heat.
What condition can result from colitis?
Colitis impacts the ability of the colon to absorb fluids with diarrhea often resulting.
Why does copper (ii) oxide increases in mass one exposure to the atmosphere?
All powders absorb water vapors from atmosphere.
What happens to temperature as altitude increases in the exosphere?
In the exosphere, temperature increases with altitude. This is because the few particles in this layer can absorb large amounts of solar radiation, leading to higher temperatures the higher you go.
Does absorbance increase or decrease as the solution concentration of the substance increase?
Absorbance typically increases as the solution concentration of a substance increases. This is because absorbance is directly proportional to the concentration of the absorbing species, as described by the Beer-Lambert Law. As more molecules of the substance are present in the solution, more light is absorbed, leading to higher absorbance readings.
Differentiate exothermic from endothermic reactions?
Exothermic reactions release heat energy to the surroundings, usually in the form of light or heat, resulting in a temperature increase. In contrast, endothermic reactions absorb heat energy from the surroundings, resulting in a decrease in temperature as the surroundings get colder.
