How can you determine the melting point of a substance based in its heating curve?
Heating curves (temp vs time) show the transition of a solid to a liquid to a gas. The solid begins to absorb heat, which is represented by a gradual increase in your curve starting from the origin. Eventually, the solid will reach the melting point, at which the temperature will cease to increase until it has fully transitioned to a liquid phase. Therefore, the melting point is the y-value correspondind to the first horizontal portion of the heating curve.
When can convection occur in a substance?
Convection can occur in a substance when there is a temperature gradient present, meaning that one part of the substance is hotter than another. This temperature difference causes the warmer, less dense portion of the substance to rise and the cooler, denser portion to sink, creating a convection current.
The H2O portion of the formula BaCl2 H2O indicates that this compound is a?
hydrate. It means that the compound has water molecules incorporated within its crystal structure. In this case, the compound is a hydrate of barium chloride.
What is part charge?
this is my full name
What the free energy will be if the temperature is kept uniform in a system?
If the temperature is kept uniform in a system, the free energy will remain constant. Free energy, also known as Gibbs free energy, depends on temperature and is a measure of the system's ability to do work. When the temperature is held constant, there is no change in the free energy of the system.
What does the flat portion of the temperature time graph indicates?
The flat portion of a temperature-time graph indicates a phase change where the substance is either melting or boiling. During these phase transitions, the temperature remains constant as the substance absorbs energy to change its state rather than increase in temperature.
Describe how the temperature of different flames could be investigated using wires?
If we held a wire a on upper portion so it is not very hot and middle portion is too hot ,inner is cold
What does indicates mean on math?
Dose is a measured portion of a medicine.
What portion of the ECG indicates ventricular repolarization?
The portion of the ECG that indicates ventricular repolarization or recovery is the t wave. It is the wave found after the QRS complex (Ventricular depolarizaton) in a normal ECG
What portion of the mantle is hot enough to begin melting rocks into magma?
asthenosphere
What is thought to form by partial melting and in situ crystallization of the melted portion?
migmatite

Describe an experiment that would you to determine whether the deep purple portion of the leaf is photosynthesizing?
You could conduct an experiment by covering the deep purple portion of the leaf with aluminum foil, leaving the green portion exposed to light. After a period of time, test both portions for starch using iodine solution. If the green portion turns blue-black while the purple portion remains light, it would indicate that photosynthesis is occurring in the green part but not the purple part.
Which cpt modifier indicates that only the professional portion of the service was performed?
-26
How aluminum melts at 460 degrees in galvanizing zinc pot although its melting point is 660?
formation of low melting point solutionsAll metal melting point in alloy form with other metal is vary according to its portion and always less than its pure condition. Please see the Zn-Al phase diagram. You can find that when the Aluminum portion in the zinc bath is less than 10%, the Zn-AL alloy melting point is less that 450 C.
What is Fractional melting?
Fractional melting is a process in which rock is partially melted, resulting in the separation of the molten portion (melt) from the solid portion. This can occur in the Earth's mantle when rocks are subjected to varying degrees of heat, leading to the generation of magma with a composition different from the initial rock.
What is a dependent variable in an experiment?
A dependant variable in an experiment is the portion of the experiment, or "y" variable that is subjected to change as a result of the various forms of the independent variable, or "x" variable.
