What must be added to a solid before it will dissolve?
LIQUID
How could you dissolve more solid solute in saturated solution in liquid solvent?
Increasing the temperature the solubility increase.
Is there a maximum temperature for a solid to dissolve?
The temperature must be under the decomposition temperature of the substance.
What must occur for a solution to form?
The correct answer is as follows: One Substance Must Dissolve In Another.
What must happen to the temperature of the liquid for vaporization to occur?
The temperature of the liquid must reach its boiling point for vaporization to occur. This is when the liquid molecules have enough energy to overcome the intermolecular forces holding them together and escape into the gas phase.
What characteristics must a liquid have before it can be used in a thermometer?
A liquid used in a thermometer must have a consistent and easily measurable expansion and contraction rate with changes in temperature. It should not solidify or boil within the thermometer's temperature range, and it should have low volatility to prevent evaporation. Additionally, the liquid should be non-toxic and chemically stable.
Do solutions dissolve solids?
Yes, solutions can dissolve solids. When a solid substance is mixed with a liquid solvent, the particles of the solid break apart and disperse evenly into the liquid, forming a solution.
What does it mean if a liquid turns into a solid?
The temperature affecting the liquid must have been below freezing for the liquid to turn into a solid.
What is meant by saturation temperature and saturation pressure?
The temperature and pressure of the atmosphere must be at that point or in an interval of values for the substance to be saturated. When mixing solutions, the temperature and pressure must be within a certain range for the substance to dissolve.
What happens to the temperature when a liquid changes into a gas?
The temperate of the liquid must rise in order to evaporate into a gas.
What must be done to oxygen to change it to a liquid?
To change oxygen gas into a liquid, it must be cooled to a temperature below its critical temperature of -118.57 degrees Celsius. This can be achieved by compressing the gas while simultaneously cooling it.
What temperature kills yeast?
Respiration requires enzymes to catalyze the oxidative breakdown of glucose, the respiratory substrate for respiration. Enzymes in yeast require an optimum temperature of about 30-40 degree Celsius. Hence temperature is closely tied to the rate of respiration in yeast.
