Is boiling points and freezing point are an example of a chemical property b physical property c energy or d matter?
b physical property
Write 3 differences between chemical and physical change?
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)
A chemical reaction involving substances a and b stops when b is completely used What would B be?
The final product
How do I find the latitude and longitude Point A for a specific point based on a known latitude and longitude Point B and a known distance between Point A and Point B Is there a formula?
If we understand the question, you're describing a circle on the surface of the earth, with its center at 'Point B', and its radius equal to the known distance. According to your specifications, 'Point A' can be any point on the circle. If you were to also specify the 'azimuth' (bearing or compass direction) from 'Point B' to 'Point A', then 'Point A' could be located by means of a formula which, though comparatively neat and tidy, would need to involve quite a bit of trigonometry.
Where is the temperature of the mantle greater point a or point b?
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.
Is a physical change A. an iron bar rusting B. oil floating on water C. a copper skillet tarnishing D. the sublimation of dry ice?
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.
Three test tubes labeled A B and C contain substances with appromimately the same melting points. How could you prove the test tubes contain three different chemical compounds?
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.
Is boiling points and freezing point are an example of a chemical property b physical property c energy or d matter?
b physical property

B: Physical Property
What does journey mean?
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.

Define the term physical property?
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).
What substances are used illicitly by athletes to increase muscle strength and physical stamina A. Amphetamines B. Barbiturates C. Benzodiazepines D. Anabolic steroids?

What are some possible physical properties?
some physical properties are how something looks, smells, sounds, or tastes or it could be the melting or boiling point of an object
Why are the boiling points of liquids above room temperature whereas those of gases below room temperature?
We refer the state of matter to atmospheric Pressure and Temperature. Substance A is consider common as liquid if the boiling point of A is above room temperature. Substance B is consider common as gas if the boiling point of B is below room temperature. A gas is already boiled, so the boiling point must be below the current temperature. A liquid has not been boiled, so the temperature must be increased in order for the liquid to boil.
