What is the cause of surface tension? What causes Gravity? What is the factor that determines the categorization of the forces? What is destructive interference? What is the cause of escape velocity? What is the cause of the conductivity of an atmosphere?
What is the vapor pressure of ethanol at 16 �C.? Ethanol has a heat of vaporization of 38.56kJ/mol and a normal boiling point of 78.4 �C. How is boiling point affected by elevation? How will the boiling point of a substance be affected by (a) increasing and (b)...
3. Surfactant - Reduces surface tension to ensure uniform mixing. Emulsifiers, a special type of surfactant, enable the uniform mixing of two liquids. Hydroxyethyl urea is colorless and odorless. It is a derivative of urea and an effective moisturizer that helps the skin retain water, resulting ...
While the pump causes the solution to flow at a constant rate, charges accumulate at the surface of the liquid. Soon a point is reached where the electrostatic repulsion is larger than the surface tension that results in the liquid meniscus deforming into a conically shaped structured known as...
The spraying process starts when the solution is pumped at a constant flow rate and a specific voltage is applied to create an electric field between the needle tip and the collector. Charges accumulate at the liquid surface. When the electrostatic repulsion is higher than the surface tension, ...
great deal, they often collide with each other or with the container holding the liquid. These collisions cause energy to be transferred between molecular entities. When enough energy is transferred to the liquid's surface, it can break the bonds of surface tension, causing the liquid to ...
What is hydrogen bonding and how might hydrogen bonding be used to explain the substantial difference in boiling between ethanol CH3CH2OH (grain alcohol) and dimethyl ether (CH3OCH3)? Explain the nature of the bonding of H2O. What is covalent bonding? Define it. Explain w...
Polarity plays a role in other physical properties, such as surface tension, solubility, and melting and boiling points. A liquid boils when it is heated andkinetic energybetween the molecules increases to the point where the intermolecular bonds break. When water molecules are boiled it takes on...
Place the graduated cylinder in a flat surface and match the height of the liquid column directly with the level of your eye. Due to the superficial tension property of the liquid, this will tend to curve downward. This curve is known as meniscus...
