Which Heats Up Faster; Sand or Water?

Before the experiment, several pieces of glass were put into an oven to dry, and the heat from the

The dependent variable in the experiment was the temperature and energy absorbed by the water.

In this experiment, the results of the tested materials gave off heat and the change in the temperature was positive because when one substance was added to another the temperature increased. A calorimetric constant is required because the calorimeter that was made is different for every lab group.

Sand dunes act as a natural barrier against coastal storms and beach erosion caused by strong, destructive wind and waves. They are a vital part of maintaining our beaches as they absorb the impact

In this lab, there are two days. In the first day, there are is part A and part B. Part A is further divided into three experiments. In experiment one, we were to figure out the heat capacity of the calorimeter that we made. The next two experiment’s goal was to calculate the enthalpy of 2 reactions and using hess’s law, figure out the heat of formation of magnesium oxide. In a reaction, there are

Scientists model the manner in which a liquid wets fibers, gaining useful insights for improving glass wool properties. Sandcastles are a prime example of how adding a small amount of liquid to a granular material changes its characteristics

Independent: The independent variable in the following experiment is the temperature as it is what is being changed and will impact the overall outcome of the experiment.

Substances A and B have an appearance of a white solid like. Substances A and B were put into a test tube and on the Bunsen burner. As a result, B melted faster than A. A was slow to melt. The reason why B melted faster than A is because it has a lower boiling point than substance A which made it melt faster. It also shows that A needs more energy than B to be broken down.

could be the reason? The experiment was conducted at 6600ft. Water tends to boil at a lower temperature at higher altitudes.

2. Some of the outside variables that could have affected our outcomes for the experiment are the ambient temperature and how quickly the groups took the hot dogs out of the ice water to measure their temperatures. The ambient temperature was 28 degrees Celsius, the coldest temperatures of the hot dogs ranged from 35 to 37 degrees Celsius, so for the groups that measured their hot dogs’ temperature quicker, they gave their hot dogs a head start in the warming process. For groups that were not as quick with their measurements, their hot dogs starting warming up at a later time, so by the time the experiment was over, their temperatures would have been lower than the groups that measured quickly. We did not control these outside variables because we did not increase or decrease the room temperature by turning on the AC.

The purpose of this experiment was to investigate the effect that different liquids would have on gummy bears. To do this we brought in different liquids, such as Fanta soda, salt water, water, and baking soda water. My hypothesis is, If you put gummy bears in different liquids then they might dissolve or enlarge. This experiment was tested on 9-14-17 and my group and I started gathering data, we started with 1 minute, 5 minutes, and then 24 hours. There wasn’t much change in the 1 and 5 minutes, the real change happened overnight. The next day of this experiment the gummy bears had mostly enlarged and softened, there was one that accomplished to do the exact opposite, the salt water gummy bear decreased and hardened. I believe that the salt

Initially, when water was added to sand, the sand was unchanged. After several minutes, the sand continued to appear unchanged.

Question: Will changing the water temperature affect how quickly a gummi bear dissolves in water? Hypothesis: If the temperature of the water is warmer, then the gummi bear will decrease more quickly in size than compared to cooler temperatures. Materials: Gather the following materials including: •safety equipment including: goggles, gloves, and apron •two 25 mL beakers •one graduated cylinder •one thermometer •one hot plate •8 red gummi bears from the same brand •20 mL of normal tap water in each beaker •one balance measured in grams •forceps •paper towels Procedure: 1.Gather all the materials listed above. 2.Include data tables in your experiment by doing two trials.

The formula for calculating the effect of sugar on the boiling point of water is linear, every additional gram of sugar has the same effect of boiling point of a liter of water, ionizing solutes, such as salt, imat the boiling point of water much more significantly in the case of salt, that same gram elevates the boiling point of a liter of water by 1.87 degrees fahrenheit (a scale based on 32 for the freezing point and 212 for boiling point of

Well, liquids with more density will evaporate slower because they have more attraction between their molecules. This information came from: WWW.enotes.com/homework-help/why-do-some-liquids-evaporate-easily-faster-than-319881 .
