How does placing hand warmers in boiling water reset the crystals?
Placing hand warmers in boiling water helps reset the crystals by reversing the chemical reaction that occurs when the hand warmer is activated. Boiling water dissolves the crystals back to their original liquid state, allowing them to solidify and be reused.
What do crystals and boiling water make?
the water evaporates leaving salt crystal
Why do you dissolve jelly crystals in boiling water?
Dissolving jelly crystals in boiling water activates the gelatin, allowing it to dissolve completely and evenly. The heat helps break down the sugar and flavoring components in the crystals, ensuring a smooth texture without lumps. Additionally, using boiling water speeds up the dissolution process, making it easier to achieve the desired consistency for the jelly. Once dissolved, the mixture can then be cooled and set into its final form.
What is the independent variable in this experiment what effect does table salt have on the temperature of boiling water?
The independent variable in this experiment is the amount of table salt added to the boiling water. The effect of adding salt to the water is to raise the boiling point of the water, therefore increasing the temperature at which the water boils.
How can crystles be growen out of just borax and boiling water?
Crystals can be grown from borax and boiling water by creating a supersaturated solution of borax in the water. As the solution cools, borax particles start to come together and form crystals. By allowing the solution to sit undisturbed for a period of time, large borax crystals will begin to grow.
What effect would dissolving some copper sulphate crystals in the water have on its boiling point?
Adding copper sulphate crystals to water will raise the boiling point of the solution, as the dissolved particles disrupt the water molecules, making it harder for them to escape as vapor. This results in an increase in boiling point compared to pure water.

What is manipulated variables in experiment about boiling point of water?
Manipulated variables are variables that a scientist deliberately adds in to tweak the outcome of his or her experiment. For instance, a scientist may choose to add certain compounds into a pot of water to see if it may affect the boiling point.

What is the independent-dependent variable when boiling regular water and salt water?
In an experiment comparing boiling regular water and salt water, the independent variable is the type of water used (regular water vs. salt water), as it is manipulated by the experimenter. The dependent variable is the boiling point of the water, which is measured to observe how it changes based on the presence of salt. The experiment aims to determine how the addition of salt affects the boiling point of water.
What is a scientific question for a boiling water experiment?
How does the altitude at which water is boiled affect the temperature at which it boils?
Does boiling salt water leave residue?
Yes it does. The water evaporates off leaving salt crystals behind. Depending on how fast you evaporate the water, different sizes of crystals are formed. The slower you evaporate, the larger the crystals.
How do you get a hypothesis for how do you make borax crystals?
To form a hypothesis on making borax crystals, you could propose a statement that predicts the outcome of the experiment based on your understanding of the process. For example, your hypothesis could be: "If I dissolve borax in hot water and allow it to cool slowly, then I predict that larger crystals will form compared to when the solution cools quickly." This hypothesis can guide your experiment and help you determine if your prediction is correct.
A hypothesis for boiling salt water and regular water?
After boiled salt water, there will be some crystals left, but regular water will vaporize and left nothing.
