What else can I help you with?
Which would evaporate quicker Water on a flat tray or water in an open bottle. with particle theory?
Water on a flat tray would evaporate quicker because there is a larger surface area exposed to the air, allowing more water molecules to escape into the air. In the open bottle, the surface area of water exposed to the air is smaller, so the rate of evaporation would be slower.
Why do you put a tray of water in the freezer to make ice?
Putting a tray of water in the freezer allows the water to freeze slowly and evenly, resulting in clear ice without trapped air bubbles. Additionally, the shallow tray shape allows for quicker freezing and easier removal of the ice cubes.
Is it a physical change when water in an ice cube tray freezes?
Yes, freezing of water in an ice cube tray is a physical change. It involves a change in state from liquid to solid without altering the chemical composition of water molecules.
What makes ice cubes stick in the tray so they won't come out?
Two things: Water expands as it freezes which applies force to the inside of the ice cube tray, holding it in place. Most ice trays are plastic and semi-porus. Some of the water molecules find their way into these small pores and when they freeze, joining to the rest of the cube, it acts kind of like molecular velcro.
What process would occur if you filled an ice cube tray with water and put it in the freezer overnight?
The water would freeze due to the cold temperature in the freezer. As the water reaches its freezing point, the molecules slow down and form a solid structure, turning into ice. This process would continue until the water in the ice cube tray is completely frozen.
Which freezes first out of hot water and cold water?
Cold water. It doesn't have to cool as much as hot water does, thus it freezes faster. Under VERY specific labratory conditions, it can be made possible to have warmer water freeze faster, however, these conditions will not be present when you fill your ice tray. If you want ice, use cold water.
What Infer What will happen if you completely fill an ice tray with water?
If you completely fill an ice tray with water, the water will expand as it freezes, potentially causing the ice tray to overflow. This expansion occurs because water expands by about 9% when it freezes. If the tray is filled to the brim, the ice may push against the edges, possibly leading to spills or cracking of the tray. To avoid this, it's best to leave a small gap at the top when filling the tray.
Why does ice spew upward in an ice tray?
When water freezes it expands and the only way it has to go in an ice tray is up.
Which would evaporate quicker Water on a flat tray or water in an open bottle. with particle theory?
Water on a flat tray would evaporate quicker because there is a larger surface area exposed to the air, allowing more water molecules to escape into the air. In the open bottle, the surface area of water exposed to the air is smaller, so the rate of evaporation would be slower.
When filling an ice tray what's best hot or cold water?
cold water is best because it will freeze faster
Can cold water freeze faster than cold water?
Think about it this way... If you start out with hot water, it has to cool its freezing temperature before it will freeze. Somewhere along the process it will become the same temperature as "cold" water - whatever temperature you choose to define as "cold". It takes time to reach that "cold" temperature and from the point that it becomes cold until it freezes should be the same as it was for water that started out "cold". All else being equal, cold water will freeze faster than hot water. Notice that I said "all else being equal". There are situations where water that starts out hot may freeze faster than the cold water. As an example - if you fill two ice trays with water - one with cold water and one with hot - and stick them into the freezer, the hot tray will start melting any frost or ice it is placed on. As it does so, it provides better contact with a cold surface that will act as a heat sink as it cools down. Having formed this better contact, it will begin to cool through both conductive and convective heat transfer. The tray that started out cold but which has poor thermal contact with its surroundings mainly cools by convection. Because conductive heat transfer is usually faster than convective heat transfer, the initially hot tray may catch up to the temperature of the initially cold tray and then continue to cool faster because of the boost from conductive heat transfer. Notice that the conditions have to be right for this to occur - the hot tray has to be warm enough to do the melting and establish the good surface-to-surface contact for the conductive heat transfer; there has to be frost or ice for it to be melting, the cold tray can't be too cold or it will start freezing before the hot tray catches up; likewise, the hot tray can't be too hot or it won't catch up to the cold tray; the freezer can't have too much forced convection (fan blowing in the freezer) but rather be primarily natural convection; the cold tray can't be warm enough to melt the ice or frost like the hot tray.

How can I quickly make ice cubes using boiling water?
To quickly make ice cubes using boiling water, pour the boiling water into an ice cube tray and place it in the freezer. The hot water will freeze faster than cold water, resulting in quicker ice cube formation.
Is it a physical change when water in an ice cube tray freezes?
Yes, freezing of water in an ice cube tray is a physical change. It involves a change in state from liquid to solid without altering the chemical composition of water molecules.
How do you clean sticky oil from an enamel baking tray?
soak in cold water.
Why does water cool down quicker in a tray with a larger surface area?
Water cools down quicker in a tray with a larger surface area because there is more area for heat exchange with the surrounding air. The increased surface area allows more water molecules to come into contact with the cooler air, facilitating faster heat transfer and cooling.
Why your finger sticks to a metal ice tray just taken from the refrigerator?
This is a matter of melting and freezing. When you touch the tray, the warmth from your finger quickly melts a bit of a ice and creates a thin layer of water between the tray and your finger. Since the tray is so cold, it quickly freezes that thing layer of water forming an icy bond between your finger and the tray.
