Sand is a solid, so all the particles are closer together. This means that when heat energy is applied to it, the molecules vibrations can affect the the molecules close to it because all the molecules are so close together.
However, in a liquid, the molecules aren't as close together - they're random and just everywhere, with some molecules being quite far apart from another [but still attached to eachother], so it's harder for the vibrations from the heat energy to pass on from one molecule to another.
What else can I help you with?
What method of separation would be used to separate sand from water?
To separate sand from water, you can use the method of filtration. Pour the sand and water mixture through a filter paper or a sieve. The sand particles will be trapped on the filter paper or sieve, while the water will pass through, resulting in the separation of sand from water.
Why does it take longer for water to boil when there's more of it?
It takes longer to boil because there is more of it that therefor takes longer to heat up. This is because a larger volume of liquid is needed to be heated to the same temperature as a small volume of liquid.
What kind of flame takes longer time to boil water using Bunsen burner?
A yellow flame would take longer to boil water using a Bunsen burner compared to a blue flame. This is because the yellow flame is cooler and provides less heat energy for boiling water.
How do you get dry sand and water from wet sand?
One way to get dry sand and water from wet sand is to let the wet sand dry in the sun. The water will evaporate, leaving behind dry sand. You can also use a strainer or filter to separate the water from the wet sand.
How would you separate a mixture of sand and salt?
Evaporation is recommended. Firstly, put salt and sand into water and stir well to dissolve the salt. Secondly, filter out the sand from the salt solution using a filter funnel and filter paper. Thirdly, place the beaker of salt solution on a Bunsen burner until it evaporates fully and only salt crystals are left. Lastly, heat the salt crystals and sand until it is dry.
Will sand or water heat quicker?
sand will because the molecules of sand are closer together, which makes heat get to the whole object faster, unlike water in which the molecules are spread apart, so it will take longer for all of the heat to get the whole liquid. (i did an experemint in my class, which proves my answer.)
How fast does water put out fire compared to sand?
Water would take longer because it is a liquid. Sand would put it out faster
What does water take longer o do than land?
Water takes longer to heat up and to cool down then it does for land.
Does the amount of water affect when the water boils?
yes. the more water the longer it would take for the heating element to heat the water. the less water, the less time it would take to heat.
Does it take longer for water to cool or heat up?
It takes longer to cool off, but mostly depending on the temperature.
When you add an object in water why does it take longer to heat up?
because the object needs also to heat up
Why does water take longer to melt than tomato sauce?
Because when you are cooking sauce it's thicker then water so it takes longer to heat.
Why is the sand hot only on the top layer and why does heat?
Sand at the surface heats up quickly because it absorbs sunlight, which warms the particles at the top layer. Deeper layers of sand take longer to heat up because sunlight penetrates less effectively. Heat is transferred in sand through conduction, with the top layer passing on heat to lower layers.
Why does it a take a full kettle of water to boil longer than a half full kettle?
The more water in the kettle, the longer it will take to reach boiling point. This is why it is wasteful in energy to boil a full kettle if you only want to brew a small cup of tea.
Why does it take water longer to cool down?
Because the specific heat of water is very high. In fact, water has about 1400 times more heat carrying capacity than air.
What did you notice about the way the soil particles sank in the water How was it different from the way the soil and sand particles sank?
I noticed that soil particles took longer to settle in water compared to sand particles. Soil particles have smaller particles sizes and more organic matter which makes them less dense than sand, causing them to take longer to sink. Sand particles are larger and denser, so they settle more quickly in water.
Why does the ocean take longer to heat up and longer to cool down?
The high heat capacity of water means that it requires more energy to increase its temperature, leading to a slower rate of heating. Additionally, the mixing and circulation of water in the ocean contribute to a delayed cooling process as heat is distributed throughout the water mass.
