1. Adding various salts to water can raise the freezing point -see News link in Related links below this box
2. Add methanol (according to ISIS, the Science & Technology Council, Oxford, UK.) They say the effect of hydrophobic molecules on water is usually to raise the freezing point, and that, at 150 bar, whilst the atomic concentration of methane dissolved in water is only about 1%, this solution freezes at +14o C. -see ISIS link.
What else can I help you with?
How does adding salt to water affect the temperature?
It does not affect the temperature of the water, but solutes raise the boiling point and lower the freezing point.
What are the effect of impurities on the freezing point of water?
Impurities in water lower its freezing point and raise its boiling point. This occurs because impurities disrupt the formation of ice crystals, requiring a lower temperature to overcome these disruptions and freeze the water.
How much heat is necessary to vaporize 500 grams of ice at its freezing point?
The heat required to vaporize 500 grams of ice at its freezing point is the sum of the heat required to raise the temperature of the ice to its melting point, the heat of fusion to melt the ice, the heat required to raise the temperature of water to its boiling point, and finally the heat of vaporization to vaporize the water. The specific heat capacity of ice, heat of fusion of ice, specific heat capacity of water, and heat of vaporization of water are all needed to perform the calculations.
What means that a large amount of energy is required to change the waters temperature?
Water has a high specific heat capacity, meaning it can absorb or release a lot of heat energy without its temperature changing much. This is why it takes a large amount of energy to raise or lower the temperature of water compared to other substances.
If a substance has a specific heat less than one would it take more or less heat to raise the temperature?
If a substance has a specific heat less than one, it would take less heat to raise its temperature compared to a substance with a specific heat of one. This is because substances with lower specific heat values require less energy to raise their temperature by a certain amount.
How many calories does it take to raise the temperature one gram of water from freezing point to the boiling point?
The value is 100 calories.
How does adding salt to water affect the temperature?
It does not affect the temperature of the water, but solutes raise the boiling point and lower the freezing point.
Would extra coolant in the radiator help to keep the temperature cooler?
No, It would only raise the boiling point higher and drop the freezing point lower.
What are boiling points and freezing points are examples of what property?
Phase transition, when matter changes from liquid to solid or gas at the same temperature. This involves extra energy to effect the transition at the same temperature. The energy does not raise the temperature it changes the physical structure.
Will the temperature go higher or lower if you add salt to the water?
Adding salt to water will lower the freezing point and raise the boiling point of the water, but it will not directly affect the temperature at which the water is heated or cooled.
Can snow melt at 30 degrees F?
Yes, snow can melt at 30 degrees Fahrenheit if there is sufficient sunlight or warmth to raise the temperature above freezing. Snow can melt when the ambient temperature is at or slightly above freezing as long as the snow is exposed to heat sources like the sun.
How does the temperature change during the freezing of water?
The temperature of the water will not change during a phase transition. If you have seen a graph of temperature versus heat input of water before, you can see that at the freezing point and the boiling point, the temperature remains constant while heat input increases. This is because during the phase transition (such as from solid to liquid), the heat put in will be used to separate the molecules and overcome the electrostatic forces between them, rather than to raise the temperature of the substance. Therefore, at the freezing point, it is possible to have both solid ice and liquid water at the same temperature.
Is it harder to raise the temperature of a rock than it is to raise the temperature of water?
It is harder to raise the temperature of water than it is to raise the temperature of a rock. It takes 1 calorie of energy to raise the temperature of 1 gram of water by 1 degree C, whereas it only takes 0.02 calorie to heat a gram of rock to that temperature.
What are the effect of impurities on the freezing point of water?
Impurities in water lower its freezing point and raise its boiling point. This occurs because impurities disrupt the formation of ice crystals, requiring a lower temperature to overcome these disruptions and freeze the water.
What do you use to raise the temperature on a fish tank?
A heater can raise the temperature of a fish tank if needed
Why do people use a lot salt when it snows?
salt makes the ice not slippery so you wont slip and fall on your butt. it also lowers the freezing/melting point of water. by lowering the freezing point, the ice will have to raise less degrees or the current temperature will be higher than the new freezing point so the water will just melt.
Does adding more solute to a solvent raise its freezing point lower its boiling point raise its boiling point or does not affect its boiling point?
Adding more solute to a solvent raises its boiling point and lowers its freezing point. This is known as boiling point elevation and freezing point depression. The presence of solute particles disrupts the organization of solvent molecules, making it more difficult for them to change phase.
