1,the average kinetic energy of a molecule in a liquid___a)gets larger when temperature increasesb)doesn't change when temperature increase2,why does warm water evaporate faster than cold water?a)energy needed to break a molecule out of the surface of water is less if the water is warmer...
The temperature of a gas is related to the average kinetic energy of its molecules by the formula:average K. E. =T where k = 1.38 x 10-21JK-1 and T is the temperature in kelvin (K).The mass of an oxygen molecule is 8 times greater than the mass of a hydrogen molecule. Two ...
Assertion: A gas can be easily liquefied at any temperature below is critical temperature. Reason: Liquification of a gas takes place when the average kinetic energy of the molecules is low. View Solution If the average kinetic energy of a molecule of hydrogen gas at 300 K is E , then th...
Kinetic Energy:Kinetic energy is energy in the form of motion. All molecules are rapidly moving, so they all have kinetic energy. The faster a molecule is moving, the more kinetic energy it has. Temperature:Molecules are so small that their kinetic energy cannot be observed. However, the av...
Transfer of heat takes place from a body at higher temperature to a body at lower temperature, till both the bodies acquire a final equilibrium temperature. This is the basic principle of calorimetry.Answer and Explanation: The molecular average kinetic ...
Average Local Ionization Energies as a Route to Intrinsic Atomic Electronegativities Historically, two important approaches to the concept of electronegativity have been in terms of: (a) an atom in a molecule (e.g., Pauling) and (b) the che... P Politzer,Z Peralta-Inga Shields,FA Bulat,...

The results indicate low average molecular weight values, which is most consistent with the recent understanding of DOM. A possible DOM size distribution is discussed to reconcile the small nature of DOM with the large-molecule behavior observed in other studies. 展开 ...
The rising vapor molecules are going to raise their kinetic energy (energy which a body possesses by virtue of being in motion.) Most of this jump is produced from the vapor’s immediate environment, which also is cooled. This means, when water is put in shallow trays during the cool ...
