Why is the water wet?
Water is wet, in the sense of being a liquid which flows easily, because its viscosity is low, which is because its molecules are rather loosely joined together..
What liquid has the highest specific heat?
WaterWater has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius. For water, this amount is one calorie, or 4.184 Joules.
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.
Which one has the highest boiling point?
Video Explanation Among the noble gases, Xe has the highest boiling point. The boiling points (in K) of He, Ne, Ar, Kr, Xe and Rn are 4.0, 27.0, 87.0, 121, 165.0 and 211 respectively. On moving down the group, the atomic size increases.
Why is the boiling point of water higher than the boiling point of chlorine?
the boiling point of water is higher than the boiling point of chorine because water is held together by polar covalent bonds which are stronger than the nonpolar covalent bonds holding chlorine together. it takes more energy to separate the water molecules because they are strongly attracted to one another.
Why is the specific heat of water so high?
Water’s high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.
What causes boiling point?
The boiling point of a liquid depends on temperature, atmospheric pressure, and the vapor pressure of the liquid. When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling will begin.
What is the strongest intermolecular force?
hydrogen bondingThe strongest intermolecular force is hydrogen bonding, which is a particular subset of dipole-dipole interactions that occur when a hydrogen is in close proximity (bound to) a highly electronegative element (namely oxygen, nitrogen, or fluorine).
Why does ammonia have a high specific heat?
Liquid ammonia has a higher specific heat, just for the same reason. Even a very easier reason to understand is the water’s relatively low molar mass: 18gmol. … In addition to vibration, rotations happen a lot to water molecules. This will result in a higher heat capacity.
How do you know what has the highest boiling point?
There are 3 important trends to consider.The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. … Boiling points increase as the number of carbons is increased.Branching decreases boiling point.
What causes water to have such an anomalously high boiling point?
Compared to the other molecules around it or its heavier cousin, hydrogen sulphide (H 2 S), water has melting and boiling points that are anomalously high. This is due to the fact that the hydrogen bonds between water molecules must be broken for a phase transition to occur.
