Mass is just "the amount of stuff there is". We can measure it in kg. If I have 4kg ice and 4kg water, then the answer is "no", but I could just as easily have 4kg of ice and 5kg water, in which case the answer is "yes".
If you mean "does freezing water make it heavier?", then the answer is no - 4kg water makes 4kg ice, and they will weigh the same. However, ice has a greater volume than water*, so freezing water will make it expand.
*This is not true for every liquid/solid combo.
What else can I help you with?
How do things float?
things float because they are less denser then the water. second things do not float, the molecules from the water support the molecules from the thing on the water. that is how something heavy can float. it just has to be boyent meaning it is spread out enough so there is more water molecules to hold it up. if you mean in the air it is the same concept.
Is hot water less dense than cold water?
Yes, because the higher the temperature, the faster and more spread out the molecules, therefore making hot water less dense than cold water.
Does one cup of oil have the same mass as one cup of water?
Oil is less dense than water. Therefore, equal volumes of water and oil will not have the same mass. You can prove this by weighing each. The cup of oil will weigh less.
Are molecules in hot water different then molecules in cold water?
If you have the same volume of both then there are in cold water more molecules.
Would you expect the particles in chlorine gas to diffuse faster or slower than the particles in argon gas?
The rate of diffusion of a gas depends on the weight of the gas molecules. The heavier the molecules, the slower they move - the lighter the molecules, the faster they move. Nitrogen molecules weigh about 28 units. Chlorine molecules weigh 71 units. So we would expect nitrogen to diffuse more quickly than chlorine.
Does ice molecules has less mass than water molecules?
no it has more
Why is water denser than air?
Water is denser than air because water molecules are closer together and have a higher mass per unit volume compared to air molecules. This is due to the intermolecular forces present in water that cause molecules to be more tightly packed. Air molecules are further apart and have lower mass, resulting in air being less dense than water.
Why does water vapour have less density?
Water vapor has less density than liquid water because it consists of individual water molecules that are more spread out and have higher kinetic energy. This causes water vapor to be less compact and have less mass per unit volume compared to liquid water.
Why does cold water have less volume than cold water?
Cold water has a higher density than warm water, which causes it to have less volume for the same mass. This is because the molecules are closer together in cold water, making it more compact.
Why does cold water have greater mass to volume ratio than hot water?
molecules are less agitated and therefore more densely packed together
Is very salty water more or less dense than less salt water?
Very salty water is more dense than water with less salt because the dissolved salt molecules increase the mass of the water. This higher density causes the salty water to sink below less salty water.
How do things float?
things float because they are less denser then the water. second things do not float, the molecules from the water support the molecules from the thing on the water. that is how something heavy can float. it just has to be boyent meaning it is spread out enough so there is more water molecules to hold it up. if you mean in the air it is the same concept.
What determines if an object will sink or float in water?
An object will sink in water if its density is greater than that of water. If the density of the object is less than that of water, it will float. Density is a measure of how much mass is contained in a given volume, so objects with more mass in a smaller volume will sink, while objects with less mass spread out over a larger volume will float.
Why does warm water sit on top of cold water?
Warm water is less dense than cold water, so it sits on top of the cold water. This is because warm water molecules are more spread out and have less mass per unit volume compared to cold water molecules, causing warm water to be less dense and float on top of the denser cold water.
Why density of wax is less than water?
The density of wax is less than water because wax is less dense than water. In other words, the mass of wax for a given volume is less than the mass of water for the same volume. This is why wax tends to float on water.
Is it always true that the molecules of dense liquid are heavier than the molecules of lighter molecules?
NO. Water has a density greater than gasoline, but gasoline, octane anyway, has a greater molecular mass than water molecules.
Why does steam weigh less than water?
Steam is less dense than liquid water because steam is in the gaseous state, while water is in the liquid state. The molecules in steam are farther apart and have more kinetic energy compared to liquid water molecules, which results in steam having a lower mass per unit volume.
