To accurately describe the physical states of substances at points A, B, C, D, and E, I would need more context regarding what these points represent, such as temperature, pressure, or specific phase transitions (e.g., solid, liquid, gas). Generally, substances can exist in solid, liquid, or gas states, and their state can change due to variations in temperature and pressure. If you provide more details about points A, B, C, D, and E, I can give a more precise answer.
Boiling point and freezing point are examples of physical properties. They describe the characteristics of a substance that can be observed or measured without changing the chemical composition of the substance.
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
To determine where the density of the material is greater, we need to consider factors such as pressure, temperature, and composition at points B and C. Generally, if point B is deeper within a material or subjected to higher pressure than point C, it will likely have a greater density due to the compression of particles. Conversely, if point C is at a higher temperature or in a less compact state, its density may be lower. Thus, without specific information about the conditions at points B and C, we cannot definitively conclude which has greater density.
no, the energy needs energy to do any form of energy or work for the energy.
The temperature of the mantle is greater at Point B than Point A. The temperature of the mantle is determined by its depth which is greater at Point B than Point A. The deeper the mantle the hotter and more pressurized it is and so the temperature at Point B will be greater than at Point A.Temperature can also be affected by other factors such as the composition of the mantle and the presence of radioactive elements. In this case since both points are in the same area and have similar composition the temperature will be determined by the depth.To summarize the temperature of the mantle is greater at Point B than Point A because it is deeper and thus more pressurized and hot.
B: Physical Property
The answer is D; the sublimation of dry ice. A physical change alters one of the physical properties of a substance (e.g. size, shape, color, etc.), but it does not change the substance itself. A chemical change causes new substances to be formed. The new substances have different chemical properties from the original substance. Changes in the state or phase of matter, such as the sublimation of dry ice (solid carbon dioxide), are physical changes because the chemical compositions of the substances do not change. Sublimation is the change of an object from a solid-state directly to a gaseous state.
The changes from A to B and from B to C are physical changes. Physical changes do not alter the chemical composition of the substances involved. In this case, the changes are likely related to states of matter or physical appearance, rather than chemical composition.
Boiling point and freezing point are examples of physical properties. They describe the characteristics of a substance that can be observed or measured without changing the chemical composition of the substance.
A journey is movement from point A to point B. for example a trip to the shops can be defined as a journey. your starting destination being point A and the supermarket being point B. journeys can be physical, of the mind or inner and emotional.
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
Reactivity is not an example of a physical property. Reactivity refers to how a substance chemically interacts with other substances, while the other options (freezing point, boiling point, density) are all physical properties related to the behavior or characteristics of a substance without changing its chemical composition.
You can label the test tubes with the names or letters like A,B and C. The difference can be seen from looking at the test tubes. However; there are also tests that can help you differentiate between different substance.
anabolic steriods..
The boiling and melting points are almost unique to individual substances. If it should happen that two possible substances have the same melting point, they can still be identified by the method of mixed melting points. If substances A and B have the same melting point and you mix them, the mixture will melt belowthe tabulated temperature. Thus if you mix your unknown with a sample of what you think it is, if you are right it will still melt sharply at the expected temperature, but if you are wrong it will melt gradually and at a lower temperature.
Tearing a tissue paper is a physical change because it involves a change in the physical state of the paper without altering its chemical composition. The other options, burning a match and baking a cake, involve chemical changes as they result in new substances being formed through chemical reactions.
any property used to characterize matter and energy and their interactions. A physical property is any measurable property the value of which describes a physical system's state at any given moment in time. For that reason the changes in the physical properties of a system can be used to describe its transformations (or evolutions between its momentary states).
