What else can I help you with?
If you drop a lump of sugar into a beaker of water the sugar particles will become evenly distributed throughout the water through what?
The process is called diffusion, where the sugar particles move from an area of high concentration (the lump of sugar) to an area of low concentration (the rest of the water) until they are evenly distributed.
What does pencil lead a lump of coal and diamond have in common?
Pencil lead, a lump of coal, and diamond are all made of carbon atoms arranged in different structures. Despite their differences in appearance and hardness, they all belong to the same carbon family on the periodic table.
Why do powder chemicals dissolve faster than solid chemicals?
Powder has a larger surface area than ribbon. Now do the rest of your homework yourself!
What is another name for a lump of coal?
A lump of coal is also known as a coal nugget or coal chunk.
Why does coal dust burn quicker than lumps of coal?
Coal dust has a larger surface area compared to lumps of coal, allowing for quicker combustion due to increased exposure to oxygen. The smaller particles in coal dust also ignite more easily, leading to faster burning. Additionally, coal dust has lower density and requires less heat to ignite compared to lumps of coal.
Why is it easier to dissolve icing sugar in water that it is to dissolve a sugar lump?
The icing sugar has a greater surface area than the lump and so the reaction occurs more easily with the icing sugar powder. This in general applies to many salts and soluble compounds.
Which will dissolve faster in powdered sugar crystal sugar or lump sugar in a glass of tap water?
Powdered sugar crystal
What are the three ways that can make a sugar lump dissolve faster and why?
Warm Water (The high temp. may cause the sugar particles to met/dissolve)
Why a sugar lump takes longer to dissolve than a spoonful of sugar?
A sugar lump takes longer to dissolve than a spoonful of sugar because it has a larger mass and a more compact structure, which reduces the surface area exposed to the solvent (usually water). When sugar is in granulated form, the smaller particles have a greater surface area relative to their volume, allowing them to interact with water more efficiently and dissolve more quickly. Additionally, the compact structure of a sugar lump requires more time for water to penetrate and break it down.
What will make a lump of sugar to dissolve fast?
A lump of sugar will dissolve faster when it is broken into smaller pieces, increasing its surface area and allowing water molecules to interact more effectively. Additionally, stirring the solution can enhance dissolution by promoting the movement of water molecules around the sugar. Higher temperatures also facilitate faster dissolution, as warmer water molecules move more rapidly and can dissolve sugar more efficiently.

What is the difference in desolving a lump of sugar and powdered sugar?
Assuming the solvent liquid is hot enough to dissolve all of the sugar and that the "lump" is more coarse than the powder, putting in the higher-density lump would impose diffusion-limited decomposition. In other words, putting in powdered sugar would allow faster absorption into the liquid, since there is more surface area of sugar exposed to the solvent. However, air resistance of small sugar particles between the powder source and solvent could lead to loss through in the pouring process, limiting the efficiency of sugar saturation.
How much is a lump of sugar?
a lot
What useful form of sugar was invented in the Czech Republic?
It is lump sugar
Why do you think that is easier to dissolve powdered brown sugar tahn a big whole piece or chunk of brown sugar in water?
The finer the grains of sugar, the more surface area of individual grains is exposed to the heat. A solid lump of sugar has to melt from the surface into the centre - therefore, initially, has less surface exposed to the heat.
Does require energy from the cell.?
No.Diffusion is a passive process. This means that it carries on without any energy being supplied, except for the energy that all atoms have at temperatures above absolute zero (zero degrees Kelvin).If you leave a lump of sugar in a cup tea for a few months, it will dissolve and then spread through the tea by diffusion. No cells needed. But it's quicker to buy a teaspoon!
Why Powdered coal burns faster than a lump of sugar?
Powdered coal burns faster than a lump of sugar primarily due to its larger surface area, which allows for more efficient oxygen contact during combustion. The fine particles of powdered coal facilitate quicker ignition and sustained combustion, as they can heat up rapidly and release energy more effectively. In contrast, a lump of sugar has a smaller surface area relative to its volume, resulting in slower combustion and heat release. Additionally, the chemical composition and structure of coal contribute to its faster burning characteristics compared to sugar.
