IS HELPS!Any change that OCCURS without altering the chemical composition of a substance is a PHYSICAL change. Physical changes can include changing the color, shape, state of MATTER, or volume of a substance. It is crucial to remember that physical changes NEVER alter the chemical makeup

is a water-soluble MIXTURE of different dyes extracted from lichens. It is OFTEN absorbed onto FILTER paper to produce one of the oldest forms of pHindicator, USED to test materials for acidity. The Brainliest Answer

Dissolution COMES from the Latin WORD dissolutio, meaning "a dissolving of something." Dissolution looks very similar to "dissolve," so to help you remember the meaning, think about what happens if you put paper in WATER — it breaks apart. Hope it HELPS....PLS mark Brainliest;)

If we KEEP PLASTIC it will be WEAK so we are not USING it

❤➡The DESALINATION is carried out using thermal, ELECTRICAL, and PRESSURE systems that greatly differ in TERMS in technology, energy consumption, and cost. The most common desalination technologies in the REGION are the distillation and the reverse osmosis (RO) based plants.

We already know that a moving object shows THREE kinds of motion, the rectilinear motion, the circular motion and the periodic motion. But how do we know whether the motion is slow or fast? This we decide by seeing the speed with which an object moves. Now, what is speed? A very common word for movement, speed designates the rate of CHANGE in position. Before DISCUSSING speed LETS discuss the varying levels of motion.Hope it helps you .

tion:The molecules of the solid are TIGHTLY PACKED . Because of that the molecules could not move and that is why it becomes rigid and has a FIXED shape.Whereas , the molecules present in LIQUIDS and gases have a more interparticular SPACE and the molecules present in it move more freely than solids . That is why the liquids and gases do not have a fixed shape .

these are some COMMON ELEMENTS. HOPE this will HELP you.

tion:Filtration: Filtration is a process of SEPARATING MIXTURES. ... The LIQUID which can pass through the filter medium is called the filtrate.d) None of theseMark me as a BRAINLIST thankyou...

it WORKS on the principle that light beams scatter due to the presence of large COLLOIDAL particles in the solution which separate the light HOWEVER in a true solution the particles are not as large enough to scatter the light particles, THATS why TYNDALL effect is not seen in true solution.

son coal is formed deep (ambiguous) inside the earth’s crust has a lot to do with the way coal is formed.Coal is formed by accumulation of vegetative material, which due to time, pressure, and heat decompose from their COMPLEX organic molecules to form elemental carbon, hydrogen, oxygen, phosphorus, sulphur, nitrogen, and whatever ELSE may be there. Subsequently, compounds like methane, sulphur dioxide, oxides of nitrogen, water are formed, which gradually escape the strata, but some of it also remains trapped.What is left is carbon in coal form along with some of the formed gasses trapped in the coal body.This process OCCURS over (~30–600) millions of years. In these millions of years, there is movement of material over the deposits, which causes the material to be part of the coal seam to move sub-surface.Hence we have coal seams forming from anywhere between 30–40 metres below SEA ground to over 3 kilometres below ground.The depth at which the coal seam is found is not indicative of its AGE. The surface will undergo periods of deposition and periods of erosion which will result in change of depth at which the seam is found. This results in outcrops of coal also being found very close or on the surface.

It just means that in the aqueous NACL SOLUTION (Nacl dissolved in water) ,each 100 GRAMS of the solution contains 15 grams of Nacl in it .

The increase in density will decrease the rate of DIFFUSION. There is an INVERSE relation between density and rate of diffusion. ... Diffusion is directly proportional to TEMPERATURE as it INCREASES the kinetic ENERGY of the molecules and inversely proportional to density of the substance.

We know that at higher altitudes, the atmospheric pressure is less.so the cooking of food becomes difficult. In ORDER to MAKE it fast and EASIER, pressure cookera are used at higher altitudes.pls mark it as the BRAINLIEST answer
