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.
What is the correct definition of electrical charge and how can one choose the appropriate definition?
Electrical charge is a fundamental property of matter that determines how it interacts with electromagnetic fields. To choose the appropriate definition, one should consider the context in which the term is being used and select the definition that best fits that context.
How is the definition of sunset determined?
The definition of sunset is determined by the moment when the upper edge of the sun disappears below the horizon.
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.
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 is exothermic in nature. Therefore, in accordance with Le-Chateliere's principle, it decreases with an increase in temperature. This means that physisorption occurs more readily at a lower temperature.
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 Chemisorption Forces of attraction are vander Waals' forces Forces of attraction are chemical bond forces Low enthalpy of adsorption (20 - 40 k.J/mole) High enthapy of adsorption (200 - 400 k.J/mole) This process is observed under conditions of low temperature This process takes place at high temperatures It is not specific It is highly specific Multi-molecular layers may be formed Generally, monomolecular layer is formed This process is reversible This process is irreversible
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.
