matters anything in our universe that takes up space what is an atom a basic particle which is made up of matter what holds atoms together in a molecule, a chemical bond what is the difference between a molecule and a compound a molecule has same atoms and a compound has different atoms, table, salt, and water example of compounds what is difference between a chemical and physical property and element. A physical property can be observed without changing and a chemical property described ability to change into different substances textures and colors are examples of what property of matter, physical heating, and liquid and measuring the temperature which it boils is what kind of property? Physical Describing how messy as a gas can easily catch fires, what kind Property? Chemical. What is the difference between a physical and a chemical change? A physical change that alters the appearance of matter, but doesn’t change the substance. A chemical change produces a new substance Dissolving salt and waters. What kind of change physical change. Tarnishing metals what kind of change? Change. Burning what is what kind of change? Chemical. What is the difference between a mixture and a solution? An example of each one. A mixture is when two or more kinds of matter I’ll put together for example trail mix. A solution dissolved into another For example, salt water. What is the difference between a homogeneous mixture and a heterogeneous mixture a homogeneous Mixture has uniformity the same throughout. Heterogeneous mixture is having visually distinguishable components. Distillation purifying liquid by a process of heating and cooling. So important to separate mixtures? To separate substances, for example salt from drinking water. A graduate cylinder what are the measure measurements that we Graduate cylinder use/milliliters for length we use centimeters inches or feet and for mass we use grams. The volume of an irregular object is V equals M over D the formula for density is D equals MV. What is density of an object with the volume of 3 cm and a massive 15 g. 5 g|ml. Why is it why is dancy important property of matter? So we can identify substances and help us understand how objects will flow or sink. What is the Sol is what is being dissolved
