At what temperature do water molecules become as tightly packed as possible?

Water molecules become as tightly packed as possible at about 4 degrees Centigrade. In ambient conditions, as liquid water cools below this point of maximum density, hydrogen bonds form in the water, and it eventually freezes (becomes a solid) to give us ice. Ice is obviously less dense than water because we can see ice floating on water.

Why does solubility of alum in water change with temperature?
The water molecules spread out as temperature increases, which allows the alum to dissolve more readily. Conversely, as temperature decreases, the water molecules become more compact which causes the alum to be less soluble.
How does a temperature increase cause the rate of a reaction to increase increase?
It increases the kinetic energy of the molecules (APEX)
What happens when fat is heated for a long time?
Depending on the temperature fat will eventually become a mass of carbon and assorted molecules.
Explain Why water can evaporate from puddles even on cold days?
Because as the water molecules get heated by the sun they start to move faster and faster until they escape from the liquid and become a gas (water vapour). On a cold day or a dau without sun, this process is slower becasue the molecules move slower and find it more difficult to escape from the liquid.
Is iron at room temperature solid liquid or gas?
Iron can be a solid, liquid, or gas because it is an element and elements can become all the forms of matter
Is it possible reduce distance between molecules of gas such that it become liquid?
Yes. This can be none by drcreasing the temperature or, if the substance is not above its critical point, by increasing the pressure.
How do molecules expand?
Air expands due to high temperature water. And nothing happens to the molecules. As they move faster usually from increased temperature, they become farther apart.
How does gases change to liquids?

Why is -273.15 called absolute zero?
Type your answer here...as all gases liquify before -273.15 is reached & at -273.15 all gas molecules become stationary therefore, kelvin suggested this temperature as lowest possible temperature hence, named it as absolute zero.
How does water move in evaporation?
The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere. After evaporation water become a gas.
What happen to a substance during changes between solid a liquid?
The molecules of a solid are more tightly or securely fixed or fastened together. When heat is applied to the solid, the molecules become agitated or set in motion thus becomming more liquified.
What happen to the atom or molecules of a substance when it melts?
The intermolecular forces are weakened.
Why does the temperature of an object rises when it is heated?
Temperature is the measure of heat in a body, as measured by the motion of its molecules. As you are providing heat energy to the body, the molecules of the body gain kinetic energy (due to the principle of conservation of heat). Hence the temperature increases unless it is transferred or radiated elsewhere.
Is barometric pressure connected to the temperature?
Barometric pressure has everything to do with temperature. There is a simple way to understand the relationship... The higher the temperature is, the lower the pressure. The lower the temperature is, the higher the pressure. Reasoning: Barometric pressure is caused by expansion and contraction of gaseous molecules(the air we breathe). Heat causes the molecules to expand, and become less dense, causing the warm air to rise, and pressure to be dropped. Cold causes the molecules to contract, making the air become more dense, and fall closer to the ground. Heat is rapidly moving, generously spaced molecules. Cold is slower moving, closer spaced molecules.
What increases the volume of a substance when the temperature increases?
The cause is the thermal expansion of the material; increasing the temperature the molecules become more and more separated each from others.
When a liquid becomes a gas the break away from one another?
During a liquid heating the intermolecular forces between molecules are first weakened and then supressed.As a consequence these molecules escape from the liquid and become a gas.Boiling occur at the boiling point and in the entire volume of the liquid; evaporation occur at the surface of the liquid and is possible at a temperature under the boiling point.
Why does solubility of alum in water change with temperature?
The water molecules spread out as temperature increases, which allows the alum to dissolve more readily. Conversely, as temperature decreases, the water molecules become more compact which causes the alum to be less soluble.
