Dissolving salt with water. where do salt dissolves fast? hot or cold water?
Question:pls give me the answer..i know it is easy but pls can u giv me the steps of it using hte scientififc method?
1. Problem or Experiment: Rate salt dissolves?
2. State Hypothesis: What do you think?
3. Procedure: How are you going to find out?
4. Data: Results, what happened?
5. Conclusion: What is your answer to the question?
Think about this. Salt is hard to see dissolve.
Using instant tea, you can see what happens:
What happens when instant tea is put in cold water?
What happens when instant tea is put in hot water?
Instant tea dissolves best in which? hot water
When something is hot reactions will occur faster. Im not sure how to involve the scientific method since I am not doing an experiment.
If you want more of an explanation,
When the water is heated it's particles are put into faster motion. When the salt is added more collisions happen between salt and water since the water is now moving faster.
Anything will dissolve faster in hot water. The molecules of hot water have a higher kinetic energy and therefore are more able to combine with molecules of another substance, such as salt (NaCl). If you want steps in the form of scientific method wouldn't you have to provide a specific experiment? If so, test the rate at which the salt dissolves in cold water compared to room temperature water to hot water.
1. Problem or Experiment.
2. State Hypothesis.
hot water and that is as scientific as i get
salt dissolves faster in hot water.
high temperature speeds up the reaction rate and therefore more salt can dissolve faster.
i'm not sure about an explanation but i know that it's hot water but i think that it's because the particles of hot water are further apart so the salt particles can dissolve more easily. the cold water particles are closer together as the water is closer to freezing point. so since the particles of the hot water are further apart the particles of the salt can move around and eventually get dissolved.
that's what i think anyway. i remember it from my science class in yr 7 when i learnt about matter.
