What is the process called when a substance dissolved in a solvent?
solvent and solute
What process in the water cycle increases as the temperature increases?
Evaporation.
Under what conditions heat can be given to a substance without raising its temperature?
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
When thermal energy moves out of a substance the temptarue will?
The temperature of the substance will decrease. Scientists refer to the entire process and its effects as "cooling". But my dick is hotter. >:)
What is the shrinking of a substance called?
Since expansion is the process of a substance's dimensions increasing, e.g., thermal expansion caused by a rise in temperature, the logical opposite would be contraction.
If the temperature of a substance increases what can you conclude about the value of q?
The value of q would be negative indicating an endothermic process.
What is the process called when a substance dissolved in a solvent?
solvent and solute
What process in the water cycle increases as the temperature increases?
Evaporation.
What happens to the temperature while the water is in the process of freezing?
the temperature increases
How does temperature affect solubility of a substance which involves endothermic process in forming a solution?
endothermic substances absorb energy when dissolved. Therefore supplying energy(heat) externally will increase the solubility.
How would you expect the intrinsic volume for a polymer in a particular solvent to vary with temperature?
generally, a polymer gets dissolved in a solvent (which implies lower density and higher volume). the higher the temperature, the quicker the process, so to answer: the intrinsic volume for a polymer in a particular solvent increases with the temperature.
What do you mean by boiling process?
Boiling process is when a substance or liquid is boiled over a specific temperature. Once the temperature reaches the boiling point, the substance or liquid becomes vapor.
Describe the trend of the curve graph of temperature vs solubility decide whether the solution process is endothermic or exothermic?
Le Chatelier's principle of equilibrium can be applied here. In short, it states that if you stress a system at equilibrium, such as that when a substance is partially dissolved, the equilibrium system will shift to the right (increasing solubility) or to the left (decreasing solubility) to relieve the stress. You can treat heat as a substance in these kinds of problems, as in the following:heat + reactants products (endothermic)reactants products + heat (exothermic)In this case the dissolution equilibrium looks like this:heat + solid substance dissolved substance (endothermic)solid substance dissolved substance + heat (exothermic)If you add heat (raise temperature) to an endothermic process, it will shift to the right, causing more substance to dissolve in order to remove the stress of added heat. In other words, the solubility curve will show higher solubility at higher temperature.If you add heat (raise temperature) to an exothermic process, it will shift to the left, causing more substance to precipitate in order to remove the stress of added heat. In other words, the solubility curve will show lower solubility at higher temperature.
What is the process of dissolving called?
I think you mean solvent. A substance that dissolves another substance is called the solvent. Water is a solvent for sugar and salt, for example. The stuff that is dissolved in the solvent is called the solute.
Why does water generally move in the opposite direction of dissolved substances?
Diffusion is the process of a substance moving from an area of a higher concentration to a lower concentration. In this scenario the dissolved substance is the higher concentration and the water would go to an area with the lower concentration.
Under what conditions heat can be given to a substance without raising its temperature?
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
Whats a solute and a solvent?
Solute = the substance dissolved in a given solution. Solvent = a. the process by which a gas, liquid, or solid is dispersed homogeneously in a gas, liquid, or solid without chemical change. b. such a substance, as dissolved sugar or salt in solution. c. a homogeneous, molecular mixture of two or more substances.
