What else can I help you with?
Does the mass of water increase when it is frozen?
No, the volume it occupies and the density will change however the mass will remain constant
Why does the mass of ice increase when it melts?
It doesn't. If you have 1 kg of ice, it becomes 1 kg of liquid water. If it became more massive that would mean there were more particles appearing from nowhere, which is of course impossible. What does increase is the density, i.e. the mass of 1 metre cubed. If you start with 1 metre cubed of ice, it will form a smaller volume when it melts (but it will still have the same mass). The reason it becomes more dense is that in ice the molecules arrange themselves in a particular way so that they produce a very open structure, and when it melts they actually move closer together, because they don't have to line up in that way.
Why is there a weight difference when water freezes and melts?
Water doesn't gain or lose mass when it freezes. Ice is less dense than water, this is why it floats. It may seem heavier, but there is no way that water can gain mass from just losing energy. Water does evaporate though even at very low temperatures, so if there is an apparent weight loss it is because of evaporation.
Does the density of objects change if you melt them?
As long as none of the water evaporates as the ice melts, the mass of water left over will be exactly the same as the mass of the ice cubes. the mass of ice is less than that of water ( that's why it floats ) therefore when it melts it takes up less space ( water expands when it freezes ) so the mass ( not the size ) is greater although the weight remains the same
Why does the level of kerosene in a glass decrease when an ice cube kept in it melts?
Ice expands as it freezes, so it takes up more volume than an equal mass of water. Hence when the ice melts in the kerosene, the liquid water takes up less volume, so the level of the kerosene drops.
What does water form when it freezes?
When it freezes, water becomes ice.ICE- A surface, layer, or mass of frozen water.
When water freezes its mass increases or decreases?
When water freezes, its mass stays the same. However, its volume increases, which is why ice expands compared to liquid water.
What is thermal expasion?
Its when a liquid freezes and expands or contracts. Ex. Water when it freezes has more mass than the liquid
What thermal expasion?
Its when a liquid freezes and expands or contracts. Ex. Water when it freezes has more mass than the liquid
Do you increase or decrease in mass?
you increase or decrease mass by taking the mass out
What is the mass of aluminum after it melts?
The mass of aluminum remains the same after it melts. When a solid, like aluminum, transitions to a liquid state, its mass does not change; it simply changes form. Therefore, if you start with a specific mass of solid aluminum, that same mass will be present in the liquid form after melting.
Does higher mass cause liquids to freeze faster?
No.Because, When water freezes there is no change of mass due to conservation of mass in any physical and chemical changes.
