Question: Which Solution Has The Lowest Boiling Point?

Which metal has lowest melting point?

mercuryAmong the metallic elements, only mercury has a lower melting point (−38.9 °C, or −38.02 °F) than cesium..

What is the strongest metal in the world?

tungstenIn terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it’s a brittle metal that’s known to shatter on impact. Titanium, on the other hand, has a tensile strength of 63,000 psi.

What is the easiest metal to melt?

GalliumGallium is the metal that melts when taken in hands having a melting point of approx 29 degree celsius.

What is freezing point?

noun Physical Chemistry. the temperature at which a liquid freezes: The freezing point of water is 32°F, 0°C.

Which functional group has highest boiling point?

Lesson SummaryEthers have a higher boiling point than alkanes because they have both London dispersion forces and dipole-dipole interactions.Amines have a higher boiling point than both ethers and alkanes because they have London dispersion forces, dipole-dipole attractions, and hydrogen bonding.More items…

What is the trend of melting and boiling points?

The atoms of this group form covalent bonds with each other and therefore, there are strong binding forces between their atoms in both solid and liquid states. Melting and boiling points of group 14 elements are much higher than group 13 elements. When moving down the group, the melting and boiling points decreases.

Which has the lowest boiling point?

HeliumThe chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten.

Which solution has the lowest freezing point?

The solution which has the lowest freezing point temperature is 0.

What is the trend in boiling point?

The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. The influence of each of these attractive forces will depend on the functional groups present. Boiling points increase as the number of carbons is increased.

Does branching increase boiling point?

Branching decreases the boiling point As the length of carbon chain increases, the surface area of the compound will also increase. Van der Waals dispersion force is proportional to the surface area. So the increase of surface area increases the ability of individual molecules to attract each other.

What liquid has the highest freezing point?

ButaneButane liquifies at -0.5 °C and freezes at -138 °C (it liquifies at higher temperatures when it’s under pressure).

Why boiling point decreases down the group?

Both the melting and boiling points decrease down the group. … The decrease in melting and boiling points reflects the decrease in the strength of each metallic bond. The atoms in a metal are held together by the attraction of the nuclei to electrons which are delocalized over the whole metal mass.

What increases boiling point?

The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. The influence of each of these attractive forces will depend on the functional groups present. Boiling points increase as the number of carbons is increased.

What is the I in freezing point depression?

ΔTF, the freezing-point depression, is defined as TF (pure solvent) − TF (solution). … b is the molality (moles solute per kilogram of solvent) i is the van ‘t Hoff factor (number of ion particles per individual molecule of solute, e.g. i = 2 for NaCl, 3 for BaCl2).

Which has higher boiling point 0.1 m NaCl or 0.1 m bacl2?

NaCl dissociate to give two ions while BaCl. Hence BaCl2 posses high boiling point. Bacl2 will have higher boiling point as boiling point is a colligative property . … Consequently, 0.1M bacl2 will have higher boiling point than 0.1M nacl.

Which solution has the highest boiling point?

0.1 M MgCl2 solution has the highest boiling point. Elevation in the boiling point is a colligative property and depends on the number of solute particles. 1 mole of MgCl2 on dissociation in water gives 3 moles of ions. This is maximum number of particles as compared to other solutes.

Why is water’s boiling point so high?

The reason for the high melting and boiling temperatures is the hydrogen bonding between water molecules that causes them to stick together and to resist being pulled apart which is what happens when ice melts and water boils to become a gas.

Which metal has highest melting?

tungstenOf all metals in pure form, tungsten has the highest melting point (3,422 °C, 6,192 °F), lowest vapor pressure (at temperatures above 1,650 °C, 3,000 °F), and the highest tensile strength.

Which has maximum boiling point at one atmospheric pressure?

A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude.

What is the trend for melting point?

What is the trend of melting and boiling points in a periodic table? – Quora. The melting point of period three elements increases from sodium to silicon and decreases from silicon to argon. In general, melting point increases across a period up to group 14, then decreases from group 14 to group 18.
