How does the size of an ice cube affect its melting?
The size of an ice cube directly affects its melting rate due to the surface area-to-volume ratio. Larger ice cubes have a smaller surface area relative to their volume, resulting in slower melting compared to smaller ice cubes with a larger surface area relative to their volume. This is because the surface area is where heat transfer occurs, so larger ice cubes retain their structural integrity longer before completely melting.
How long does it take to melt plastic?
The time it takes to melt plastic can vary depending on the type of plastic, its thickness, and the temperature it is exposed to. Generally, it can take a few minutes to melt thin plastic items like straws or plastic bags, while thicker plastics like water bottles or containers can take longer. Heat from a flame, hot surface, or microwave can expedite the melting process.
What substance has a high melting point?
One substance that has a high melting point is diamond.
How can they make sure enough evaporation takes placeSuggest two different ways?
One way to ensure sufficient evaporation is to increase the surface area of the liquid by using a shallow container or spreading it out thinly. Another way is to increase air circulation around the liquid using a fan or by placing the container in a well-ventilated area.
How can one determine the melting point of a compound?
To determine the melting point of a compound, one can use a melting point apparatus. The compound is heated gradually until it changes from a solid to a liquid state. The temperature at which this change occurs is recorded as the melting point of the compound.
How do the 3 states change from one to another?
These phenomenons are called melting, boiling, vaporization, sublimation, deposition, evaporation.
What are the changes?
Sublimation, boiling, condensation, melting and freezing. One might include evaporation, though that does not happen at a particular temperature.
What are the different changes?
Sublimation, boiling, condensation, melting and freezing. One might include evaporation, though that does not happen at a particular temperature.
What are the 2 kinds of vaporization?
The vaporization that takes place below the surface of liquid is called boiling. The other one that takes place at the surface of a liquid is called evaporation
What determines the rate of evaporation?
One factor that affects the rate of evaporation is temperature. Warmer weather means a faster rate of evaporation. The density of the air or humidity in the surrounding air is also a factor. If the air is already humid, evaporation will take longer.
Give two differences between evaporation and boiling?
Evaporation takes place at all temperatures but boiling at one particular temperature When saturated vapour pressure becomes equal to the atmospheric pressure boiling takes place but evaporation is not so
Which distance is longer mile or meter?
A mile is longer, since it takes 1,609.344 meters just to equal one mile
Which planets take longer then earth to complete one rotation?
Venus takes longer than Earth to complete one rotation on its axis. A day on Venus is longer than a year on Venus, as it rotates very slowly clockwise. Mercury also takes longer than Earth to complete one rotation due to its slow spin.
Why does the amount of water flows in a river change during the year?
one Answer EVAPORATION
The process that water goes through as it changes from one state to another?
Water changes states through the processes of evaporation, condensation, freezing, melting, and boiling. These processes involve gaining or losing energy to switch between solid, liquid, and gas states. For example, water evaporates to become a gas when heated and condenses back into a liquid when cooled.
Why does Jupiter have a longer year then Mercury?
Jupiter has a longer year than mercury because it takes longer for it to revolve around the sun.
Which is longer one year on mars on year on earth?
Mars. The further out from the sun, the longer a planet takes to revolve round the sun. For example, Pluto's orbit takes over 200 (Earth) years.
