What else can I help you with?
What two factors determine if a substance will be a liquid?
The temperature of the environment and the melting and evaporation temperature of the substance.
What is a colloidal salt?
1) A colloidal system consists of two separate phases: a dispersed phase (or internal phase) and a continuous phase (or dispersion medium) in which the colloid is dispersed.2) A colloid is a substance microscopically dispersed evenly throughout another substance.
Two factors that are responsible for a phase change?
Temperature and pressure are two factors that can cause a phase change in a substance. A substance will change from one phase to another when its temperature or pressure surpass a certain threshold, known as the melting point, boiling point, or sublimation point.
How does chromatography separate molecules?
The principle is based on equilibrium of the molecules between the mobile phase and the stationary phase. This will vary depending on the polarity of the substance, and the two phases. If the substance in more soluble in the mobile phase, it will travel further, and vice versa.
Is wood a sublimatory substance?
No, wood is not a sublimatory substance. Sublimation is the process in which a solid changes directly into a gas without passing through the liquid state. Wood undergoes combustion, which is a chemical reaction that releases heat and light energy when it interacts with oxygen in the air.
How do you calculate the partition coefficient in a given system?
To calculate the partition coefficient in a given system, you divide the concentration of a substance in one phase by the concentration of the same substance in another phase. This helps determine how a substance distributes between two phases, such as between a solvent and a solute.
Name the 2 parameters which determine the physical state matter?
The two parameters that determine the physical state of matter are temperature and pressure. These parameters influence the arrangement and movement of molecules, affecting whether the matter is in solid, liquid, or gas form.
What are Two factors which determine the distance a substance travels up the paper?
The two factors that determine the distance a substance travels up the paper in paper chromatography are the solubility of the substance in the solvent and the affinity of the substance for the paper.
The phase of matter depends on what?
Heat and pressure are the two main factors that determine a substance's current phase.With high heat a substance's phase drifts toward the gaseous phase while freezing temperatures cause it to move toward its solid phase. With pressure it is the opposite. Higher pressures push the substance toward its solid phase, while lower pressures will encourage the substance to evaporate into its gaseous phase.
What two determine the state of a substance?
Temperature and pressure
What are the two parameters that are necessary to determine probabilities for a particular normal distribution curve?
Mean and Standard Deviation
What two factors determine if a substance will be a liquid?
The temperature of the environment and the melting and evaporation temperature of the substance.
What do the lines on a phase diagram represent?
The lines on a phase diagram represent the boundaries between the different phases of a substance (such as solid, liquid, and gas). These lines show the conditions of temperature and pressure at which two phases can exist in equilibrium with each other.
What 2 factors determine the state of a substance?
The two factors that determine the state of a substance are temperature and pressure. These factors influence whether a substance exists as a solid, liquid, or gas.
What is a colloidal salt?
1) A colloidal system consists of two separate phases: a dispersed phase (or internal phase) and a continuous phase (or dispersion medium) in which the colloid is dispersed.2) A colloid is a substance microscopically dispersed evenly throughout another substance.
How can one determine the phase difference between two waves?
To determine the phase difference between two waves, you can compare the starting points of the waves and measure the time it takes for each wave to reach a specific point. The phase difference is then calculated based on the difference in time or angle between the two waves.
What are the 3 phaes for Mesothelioma Clinical Trials?
In phase one the dosage and safety of a drug is determined. In phase two they determine how effective the drug is on the targeted illness. In phase three they determine how effective the drug is compared to other drugs.
