Which statement is true regarding the motion of liquid water molecules and ice molecules?
Liquid water molecules exhibit a greater amount of motion than ice molecules.
When water changes from a liquid to a gas heat and energy do what?
When water changes from a liquid to a gas, it is evaporating or boiling. The "heat and energy" of the water molecules increases in the gaseous state. In fact, water molecules must pick up energy to change state from a liquid to a gas. Water molecules that are free to move as a gas have more kinetic energy than water molecules in a liquid form (as long as the liquid is not pressurized). The "heat and energy" of the H2O molecules that are now a gas is higher than that of liquid water.It should be noted that the thermal energy (heat) necessary to cause water to change state and become a liquid must come from somewhere. In evaporation, the energy necessary for the water molecule to escape from the liquid comes from the liquid. The liquid cools. We know that if we wet our finger and blow on it, it feels cool because evaporating water cools liquid water from which it escapes. That evaporating water has taken energy from the liquid water.In the case of boiling, water molecules take energy from liquid water, but the liquid water might not be cooling. It probably isn't as that liquid water is having thermal energy (heat) pumped into it by a heat source of some kind. Turn on a burner or element on the range under a pan of water and the water will begin warming until it's boiling. As water boils off, it is taking thermal (heat) energy with it, but the remaining water doesn't cool down as the heat source continues to add more thermal energy.
Does freezing then thawing a mechanical weathering of a rock?
Yes, it is a form of mechanical weathering. Water manages to get into a crack in a rock, and with cold temperatures, freezes. When transferring from a liquid to a solid, the molecules of water expand by crystallization, widening the crack in the rock.
How does the movement of water molecules change when goes from liquid to gas?
The molecules begin to release and move into the air more quickly than they condense back into liquid.
When water vapor liquid water droplets on a window in the early morning this is an example of?
Condensation. This is gas molecules forming in their liquid state.
Why does warm water evaporate faster then cold water?
At higher temperatures waer molecules at the surface of the liquid have more energy and is more simple to escape into atmosphere.
What can turn in to a gas then to a liquid?
ANY SUBSTANCE KNOWN TO MANKIND. Iron can be a liquid at high temperatures, and can evaporate/turn-into-a-gas at even higher temperatures. water
What happerns to particles in liquid water when the water boils into steam?
At the boiling point, molecules begin to move from a liquid to a gaseous state. For individual molecules, this process (evaporation) can occur at temperatures lower than boiling.*There is still additional energy required (called the heat of enthalpy) and there must be a nucleation point from which the molecules move. Lacking these, water can reach temperatures higher than the boiling point without becoming a gas.
Why is the boiling point of heavy water higher than that of ordinary water?
The boiling point of heavy water is higher than "regular" water because the water is a bit more massive (owing to the extra neutrons stuck to protons in hydrogen nuclei) and more energy is needed to allow the heavy water to change state. Boiling means the molecules gain kinetic energy and "escape" the bonds that are holding the water molecules together in their liquid state. Those same bonds act on the heavy water molecules just like "light" water, but because those molecules are a bit more massive, heavy water molecules need more kinetic energy to "break loose" and "escape" the liquid. That means higher temperatures are required for higher concentrations of heavy water to bring it to a boil. A link is provided to the Wikipedia article on heavy water.
What forces are responsible for keeping water molecules in the liquid state?
Water is liquid when the temperature is below 100 degrees c and 0 degrees c, temperature does not apply force but the molecules vibrate faster at high temperatures than lower ones.
Why do water molecules cohere to form a liquid?
Water molecules are already in liquid form.
What is the relationship between water vapor air molecules temperature?
Whatever it is, gas, vapor, liquid, solid - the higher the temperature, the higher is the local agitation/speed of the molecules/atoms.
What is the relationship between temperature air molecules and water vapor?
Whatever it is, gas, vapor, liquid, solid - the higher the temperature, the higher is the local agitation/speed of the molecules/atoms.
What is the mass 150cm to the third power of liquid water?
At room temperature (20C) 149.7 grams. At higher temperatures it will be less.
Do water molecules in the liquid state have more energy than water molecules in the polar state?
Do water molecules in the liquid state have more energy than water molecules in the polar state
Waters high specific heat is mainly a consequence of?
Water has a high specific heat capacity because it is a relatively light molecule (18 grams per mole). The specific heats of molecules are all about the same on a per-molecule basis, especially at higher temperatures. This is called the law of Dulong and Petit. At low temperatures, it gets more complicated because the vibrations of molecules are quantized. When specific heats are measured on a per-gram basis, lighter molecules have higher specific heats. For example, the specific heat of hydrogen (H2), which has a molecular weight of 2 grams per mole, is much higher than that of water. Liquid water has a higher specific heat than most other liquids (such as alcohols) because its molecules are lighter.
Is the concentration of water molecules higher in pure water or in sugar water?
Concentration of water molecules is higher in pure water
