Is screening rocks from sand a physical change?
Screening rocks from sand is a physical change because it does not alter the chemical composition of the rocks or sand. It simply separates the two components based on their physical properties, such as size and shape.
Which two properties characterize an air mass?
Temperature and moisture content are the two main properties that characterize an air mass. Air masses are classified based on the temperature and humidity conditions they acquire from their source region.
What is crossover temperature?
Crossover temperature is the temperature at which two materials transition from one state to another, such as from solid to liquid or from liquid to gas. It is the temperature at which the properties of the materials change significantly.
What are two physical properties of sausage?
round and pink in color
What are two important properties of air?
There are more than two properties of air and all of them are important. Properties of an air mass include pressure, density, and temperature.
What are two physical properties that can vary even when the substance with these properties does not change?
Density and temperature can both vary for a substance without changing the identity of the substance. The density of a substance can change with temperature, pressure, or the presence of impurities, while the temperature of a substance can change due to external factors like heating or cooling.
What are two physical properties that can that can vary when the substance with these physical properties that dose not change?
Two physical properties that can vary without changing the substance are temperature and pressure. For example, water can exist as a solid (ice), liquid, or gas (steam) at different temperatures and pressures, but it remains chemically the same H2O molecule.
What are 2 physical properities that can can vary even when the substance with these properties does not change?
Density and volume are two physical properties that can vary even when the substance does not change. The density of a substance can vary depending on the pressure and temperature, while the volume can change with the shape or container that holds the substance.
What is the two physical properties of steam?
If the steam is being produced by boiling water the physical property is gas and the chemical properties are H2O.
What are two physical properties that can very even when the substance with these properties dose not change?
The dimensions: height, length, and width.
What Are Two Physical Properties That can vary even when the substances with these properties does not change?
Color/smell or freezing/ boiling point.
The symbol for carbon 2 physical properties?
The chemical symbol of carbon is C. Two physical properties are (1) solid at room temperature and (2) high melting point.
What happens when you mix two substances?
You get a mixture.
What are two physical properties of urine?
It is the same temperature (98.6 F) as human body when expelled, and it is acidic.
What are two physical properties that don't depend on size?
Density and melting point are two physical properties that do not depend on the size of a material. Density is the mass of a substance per unit volume, while the melting point is the temperature at which a substance changes from a solid to a liquid state.
What two physical properties of matter can change according to how much of the substance is in an object?
a book and air
What periodic table group has similar chemical properties but different physical properties?
Group 17, the halogens have similar chemical properties. However, at standart temperature and pressure, two are gases, one is a liquid and two are solids.
