Generally bonds present between molecules are called intermolecular forces. they are three types:
1) Wander Wall forces (London forces)
2) Dipole - dipole interaction.
3) Hydrogen bond.
- As molecular weight increases boiling point also increases due to surface are is directly proportional to Wander Waal forces.
- Dipole-dipole attraction: the attraction between two different polarizable molecules is called dipole- dipole attraction, this attraction play important role in boiling point.
- Hydrogen bond: electrostatic attraction between hydrogen and more electronegative atom is called hydrogen bond.
- The substance which has hydrogen bond have higher boiling point.
1-pentanol has hydrogen bond
1- Bromopentane has dipole - dipole
1-pentene has only London forces
Hydrogen bond > dipole - dipole attraction > London force
Here is a diagram comparing both plant and animal cells.
Hope it helps:)
Answer:
Explanation:
Hello,
In this case, by using the general gas law, that allows us to understand the pressure-volume-temperature relationship as shown below:
Thus, solving for the temperature at the end (considering absolute units of Kelvin), we obtain:
Best regards.
Answer:
Explanation:
Tools, instruments, apparatus are very key to research works carried out in the laboratory. The more sophisticated they become, the more efficiency they provide in making ground breaking researches.
Over the years, technological advancement has afforded scientists with new way of achieving precision and accuracy in their procedures by developing cutting edge facitlities. These equipment can help carry out better experiment and make observations simple and easy to do.
