What else can I help you with?
What do you think will happen to the temperature of a substance during a phase change?
During a phase change, the temperature of a substance remains constant. This is because the energy being absorbed or released is used to break or form intermolecular bonds, rather than to change the temperature of the substance.
Why is the temperature expected to remain constant during the thermal arrest?
I think you must mean the 'latent heat of fusion' experiment where a change of state in the cooling curve of a hot liquid like naptha or Octadecanol. the liquid cools as expected until the liquid starts to solidify. The temperature drop is arrested as the crystallisation process emits latent heat. Having solidified it then cools as expected.
Difference between latent heat from sensible heat?
Two forms of heat are relevant in air conditioning:1. Sensible Heat2. Latent HeatSensible heatWhen an object is heated, its temperature rises as heat is added. The increase in heat is called sensible heat. Similarly, when heat is removed from an object and its temperature falls, the heat removed is also called sensible heat. Heat that causes a change in temperature in an object is called sensible heat.Latent heatAll pure substances in nature are able to change their state. Solids can become liquids (ice to water) and liquids can become gases (water to vapor) but changes such as these require the addition or removal of heat. The heat that causes these changes is called latent heat.Latent heat however, does not affect the temperature of a substance - for example, water remains at 100°C while boiling. The heat added to keep the water boiling is latent heat. Heat that causes a change of state with no change in temperature is called latent heat.Appreciating this difference is fundamental to understanding why refrigerant is used in cooling systems. It also explains why the terms 'total capacity' (sensible & latent heat) and 'sensible capacity' are used to define a unit's cooling capacity. During the cooling cycling, condensation forms within the unit due to the removal of latent heat from the air. Sensible capacity is the capacity required to lower the temperature and latent capacity is the capacity to remove the moisture from the air.
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 two things does the specific latent heat of a material depend on?
The specific latent heat of a material depends on the substance being considered and the phase change involved, such as condensation or freezing.

During a phase change, the temperature of a substance remains constant. This is because the energy being absorbed or released is used to break or form intermolecular bonds, rather than to change the temperature of the substance.
What property is it when you boil water and find the temperature?
You think probable to evaporation, a change of phase.
Why does water go through phase changes?
Because the chemical of that susbstance does not change, the only change in phase transition is the physical properties. For example, water (liquid) ------> water (ice). In this phase transition water is always H2O, but now water is harden (physically). However, you may think of the interactions between the molecules, but the chemical interation between water molecules do not change, only the fact that they interact with each other more frequently, which is also physical interaction. Hope this is help
What is the word for a vapor going to a solid?
You think probable to the sublimation change of phase
What is a two phase?
A two phase furnace includes 2 types of heat. Usually it is composed of an electric heat pump and also a nat. gas/ propane heat source when the temperature drops below a set range. The reason they use these is because heat pumps are very efficient when there's not a large temperature change required, but they're efficiency drops dramatically when the outside temperature (or ground temperature) drops below freezing. The only other two-phase furnace would be a two-phase electric (as opposed to a three-phase electrical furnace.) But I don't think you're asking about 2 vs 3 phase electrical furnace systems... Those are quite rare.

What change happened to the particles in the iodine when you did this?
The particles of iodine sublimated, meaning they changed directly from a solid to a gaseous state without passing through a liquid phase. This change occurred due to the increase in temperature causing the iodine to vaporize.
Which phase of digestion occurs when you think about see or taste food?
A chemial change because during digestion carbohydrates are converted into simple sugar units,proteins into amino acids and so on, water and enzymes present in the body catalysed these reactions.
Is liquid ammonia boiling a chemical or physical change?
Physical change.. think of it as it changing state not the substance
What temperature in the solid phase has the greatest water density?
In the liquid phase, it is 4o C. seeing how water only expands as it becomes ice, i think 0 degrees celcius is the densest
What mitosis phase does the chromosomes move rapidly toward the mitotic centers?
i think its during anaphase?
What phase does DNA replication take place?
DNA replication takes place during the S phase of the cell cycle, which occurs before cell division. During this phase, the cell synthesizes a copy of its DNA to prepare for cell division.
