Fig. Microscopic objects are smaller than macroscopic objects and cannot be seen with the naked eye. The chemical name of a compound often consists of more than one word, but many compounds, like water, have common one-word names. Now we're talking about seven millionths of a meter. (b) physical property - Is observed without changing the identity of the substance. And on a similar scale, is this T-cell, you have a, you have things In order to do this, each cell keeps in constant communication with its neighbours. During cell growth, the cell ingests certain molecules from its surroundings by selectively carrying them through its cell membrane. (c) iron filings is a pure substance. Does the crystal have a definite shape? K2Cr2O7. But you immediately see on this picture how small the HIV virus is compared to the actual T-cell. WebThe only thing you can say is that organs and tissues are made of many cells, so they tend to be bigger than cells. -CHROMOSOME The diameter of the protein hemoglobin is roughly 5 nanometers. (b) apple juice - homogeneous mixture If you looked at these scales it would be much much much bigger. Can be separated by physical means. why? chemical change The sample may be a solid, a liquid, a gas, or a mixture of states.
