What effect does adding a solute have on the boiling point of a solution?
Adding a solute to a solution, or some liquid, causes the boiling point to increase. Think about water, sometimes people throw salt in their water when they're boiling noodles. This causes the boiling point to increase so the water is actually at a higher temperature (although most of the time the amount of salt added isn't nearly enough to cause any measurable change).
Which factors affect water potential in living cells?
Some factors which influence water potential include gravity, pressure, and solute concentration. Adding solute lowers the water potential. An increase of pressure will increase the water potential.
Can ordinary water be boiled in 95 degree Celsius or 105 degree Celsius?
pure water (with no impurities added ) can only boil at 100 degrees Celsius , no other temperature . But if we add impurities to it than the temperature at which the water will boil can increase or decrease. Another point is that when we increase or decrease the atmospheric pressure, the temperature at which ordinary water boils (i.e.100 degrees Celsius) can also increase or decrease.
Does a substances temperature change when it is changing state?
No. During a phase change, a substance will remain at a constant temperature until the change is complete. In the case of melting ice, the heat initially goes into separating water molecules from the ice lattice, which is melting. During that time, the heat goes into continued melting of the ice and the temperature remains constant. Once all of the ice is melted, adding additional heat will increase the temperature of the now liquid water.
What is the amount of table sugar that will dissolve in 1 kg of water can be increased by?
You can increase the temperature of the water.
Adding Glycerol to water?
Adding glycerol to water creates a glycerol-water solution. Glycerol is soluble in water, forming hydrogen bonds with water molecules. This mixture can be used in applications such as cosmetics, pharmaceuticals, and food products.
Does adding chemicals to water increase temperature?
No, adding chemicals to water typically does not increase the temperature of the water. The temperature of the water is determined by its initial temperature and any external heat sources or processes. Chemical reactions involving the added chemicals may release or absorb heat, but this would not necessarily increase the overall temperature of the water.
Why does temperature of water lowers on adding glucose?
It will increase the surface tension of water hence temperature decreases. If you add phenol to water temperature increase as it decreases the surface tension.
Which substances when added to water will cause the greatest increase and decrease in water temperature?
Adding hot water will cause the greatest increase in water temperature, as it has a higher initial temperature. Adding ice will cause the greatest decrease in water temperature, as it absorbs heat from the water to melt and reach thermal equilibrium.
What would increase the salinity of sea water?
Decreasing the temperature, evaporating water, or adding more salt.
What is superhydration?
nA state of hydration achieved by manipulation with ergogenic aid glycerol nWhen ingested with large volumes of water (1/2 litres), glycerol been shown to increase water retention in the body nReduces overall heat stress during exercise in hot conditions, lowering heart rate & body temperature nA state of hydration achieved by manipulation with ergogenic aid glycerol nWhen ingested with large volumes of water (1/2 litres), glycerol been shown to increase water retention in the body nReduces overall heat stress during exercise in hot conditions, lowering heart rate & body temperature nA state of hydration achieved by manipulation with ergogenic aid glycerol nWhen ingested with large volumes of water (1/2 litres), glycerol been shown to increase water retention in the body nReduces overall heat stress during exercise in hot conditions, lowering heart rate & body temperature
The temperature of true water is in a beaker is 25 c after adding a piece of magnesium to the water the temperature increase is this an exothermic or an endo thermetic?
exothermic ? because energy released
An increase in a body of water's temperature caused by adding warmer water is called?
Thermal Pollution.
Show by calculation how would you prepare 200ml of 80 percent glycerol?
To prepare 200ml of 80% glycerol solution, you would mix 160ml of glycerol (200ml x 80%) with 40ml of water. Calculations: 200ml x 80% = 160ml glycerol, and 200ml - 160ml = 40ml water needed. Mix the glycerol and water thoroughly to obtain the 80% glycerol solution.
What is the value of surface tension of glycerol solution?
The surface tension of a glycerol solution can vary depending on the concentration of glycerol and temperature. In general, the surface tension of a glycerol solution is lower than that of pure water due to the glycerol molecules disrupting the hydrogen bonding between water molecules at the surface.
How do the properties of glycerol and water and olive oil compare to the properties of LPG?
Glycerol and water are polar molecules, soluble in water, while olive oil is nonpolar and immiscible in water. LPG is a gas at room temperature and pressure, while glycerol, water, and olive oil are liquids. LPG is a hydrocarbon with lower boiling point compared to glycerol, water, and olive oil.
Does the volume of water affect the temperature increase when reacted with calcium oxide?
yeah the temperature does increase, when you increase the volume of water the temperature of calcium hydroxide increases too!
