We are doing an experiment on measuring the temperature. We are to measure the temperature of hot water (measure it initially, then wait for 10 minutes then measure again). Additionally, we are to measure the temperature of another water before and after putting ice (measure initially then measure 3 times [every 5 minutes] for 15 minutes). My question are:
What law or principles of chemistry could be applied in this experiment?
Should we expect the temperature of the hot water to drop? why?
Should we expect the temperature of the water to rise or drop after putting the ice? why?
I have chosen to discuss the terms heterogeneous and homogeneous for this week's discussion. I have some familiarity with these two words and most of my familiarity is in terms of cooking. There are a lot of examples of heterogeneous and homogeneous mixtures in the kitchen. A heterogenous mixture is one made up of multiple individual components, like a chocolate chip cookie or a bowl of cereal and milk. While the ingredients are blended together, they are still visibly separate. A homogeneous mixture is one that blends to the point of no individual components being visible. An example of this could be simple syrup or a pitcher of sweet tea or lemonade. The terms heterogeneous and homogeneous refer to mixtures of materials in chemistry. The difference between heterogeneous and homogeneous mixtures is the degree to which the materials are mixed together and the uniformity of their composition….just like as in the everyday usage of these terms. I feel like the similarities in the usage of…

Horror movies happen to be your favorite type of movie as well. You also know that all of these friends were born in the same week that you were, even in the same year. An astrology-loving friend hypothesizes that people born in that week like horror movies more than other genres of movies. You decide to use the scientific method to test this hypothesis. Part A What should you do next? O Come up with a theory to explain why movie preference is related to birth week. O Perform experiments to test your hypothesis.

Using this information, answer the following: 1. Do you think the student made aspirin? Why or why not? 2. How could you test your hypothesis? Explain what you would do and what the results would look like if they made aspirin versus if they didn't.arrow_forward

Which of the procedures would be the most effective way to separate the sugar from the tiny pieces of glass? Collect all of the sugar and glass pieces into a pot and heat the mixture to melt the sugar. Then, pour the liquid sugar through a filter to separate the glass from the sugar. Collect all of the sugar and glass pieces into a bucket of water. Allow the water to dissolve the sugar, then remove the water and sugar solution, leaving the glass behind in the bucket. The solution is then heated to evaporate the water, leaving the sugar behind. Use a magnifying glass and tweezers to safely remove the glass particles from the mixture.
