What is the word that goes with the definition they swing on hinges?
The word that goes with that definition is "door."
Is a drawing of an atom a scientific definition?
No, a drawing of an atom is not a scientific definition. A scientific definition of an atom would describe it as the smallest unit of matter that retains the properties of an element.
Where can I find the proper definition of transfixed?
You can find the proper definition of "transfixed" in a reputable dictionary such as the Merriam-Webster or Oxford English Dictionary. These sources will provide you with a clear and accurate definition of the word.
Does everything you can see fit the definition matter?
No, not everything that can be seen fits the definition of matter. Matter refers to physical substances that occupy space and have mass. Some things that can be seen, such as light or energy, do not fit this definition.
Which of the following is one definition of energy?
Energy is the capacity to do work or produce heat.
Why does physisorption decreases with increasing temperature?
physisorption is an exothermic reaction.so according to le chatlier's principle,as temperature increases,backward reaction is favoured
Is adsorption of oxalic acid on charcoal physisorption or chemisorption?
The adsorption of oxalic acid on charcoal is typically considered to be physisorption. Physisorption involves weak van der Waals forces between the adsorbate (oxalic acid) molecules and the surface of the adsorbent (charcoal). Chemisorption, on the other hand, involves stronger chemical bonds and typically requires more energy.
Why physisorption decreases with increase in temperature?
Physisorption involves weak van der Waals forces between gas molecules and a solid surface. As temperature increases, gas molecules gain more kinetic energy, making it harder for them to be retained on the surface through weak interactions. This leads to a decrease in physisorption at higher temperatures.
Why does physisorption decrease with the increase of temperature?
Physisorption is weaker than chemisorption and is typically dependent on van der Waals forces. As temperature increases, the thermal energy disrupts these weak interactions between the adsorbate and the surface, leading to a decrease in physisorption.
Is physisorption a reversible process?
Yes, physisorption is generally considered a reversible process because it involves weak van der Waals forces or electrostatic interactions between the adsorbate molecules and the adsorbent surface. This means that the adsorbate molecules can easily desorb from the surface under suitable conditions, making physisorption reversible.
Why does physisorption decreases with increase in temperature?
Physisorption decreases with an increase in temperature because at higher temperatures, molecules in the gas phase have more kinetic energy. This increased kinetic energy makes it more difficult for the gas molecules to be adsorbed onto the surface of the adsorbent material. Additionally, higher temperatures can disrupt the induced dipole-dipole interactions that are responsible for physisorption.
Why is enthalpy of chemisorption higher than physisorption?
The enthalpy of chemisorption is higher than physisorption because chemisorption involves the formation of chemical bonds between the adsorbate and the adsorbent surface, which requires more energy to break than the weaker van der Waals forces involved in physisorption. This leads to a stronger interaction between the species adsorbed on the surface, resulting in a higher enthalpy of chemisorption.
What is the difference between physisorption and non activated chemisorption?
Physisorption involves weak van der Waals forces between the adsorbate and adsorbent, while non-activated chemisorption involves stronger chemical bonds forming between the two. Physisorption typically occurs at lower temperatures and can be easily reversed, while non-activated chemisorption requires higher temperatures and is more difficult to reverse.
Why Physisorption is multilayered and chemisorption is monolayered?
physisorption involves van der wall attractive forces between adsorbent and adsorbed , This may result on the accumulation of many layers of the molecules on the surface. Chemosorption involves formation of chemical bonds between adsorbent and adsorbed molecule. Adsorbent have some functional groups or atoms on its surface with unsatisfied valences, once these valences are satisfied they don't undergo bond formation with more adsorbed molecules and only single layer is formed.
