5. Use a 50mL or 100mL graduated cylinder to measure approximately 50mL of hydrochloric acid.…
The dependent variable (what I will be measuring or observing) in the project is the balloon’s growth/inflation from the mixture.…
1. If the room temperature for this experiment had been lower, the length of the resonating air column would have been shorter. The length of air column is directly proportional to temperature due to v=331msT273 .…
1. Describe the relationship that you observed between pressure and volume in this lab. Refer to your data and/or graph to help support your answer. …
Temperature Measurements: Look closely at the thermometer and record to the best number of significant figures, +/- 0.1 oC. In other words report, for example 24.0 oC, not 24 oC. Calculate the last 2 columns. (1 point)…
Procedure: The Graphing and Estimating lab exercise involves materials such as: a tea light candle, a 100mL beaker, 150 mL beaker, 250 mL beaker, 400 mL beaker, a 600 mL beaker, a graduated cylinder and a stop watch. The first item at hand to consider is to make sure each beaker being used in the experiment is dry prior to use. On a flat surface, light the candle and wait for a steady flame. Place one of the beakers over the lit candle and start the stopwatch immediately. Observe the amount of time it takes for…
Create a graph of your data for this part of the lab. You may use any graphing tool to create the graph, but be sure to follow common guidelines for creating a graph. Be sure to graph temperature in the unit Kelvin and volume in the unit liters.…
• describe the effects of this change on the pressure and volume of the gas sample.…
c) (3.15 x 10-1 – 9.7 x 10-3) * [(4.7 x 10-2)/(2.33 x 10-3)] = 1.5 x 10-2…
I think the presence of the smoke contributed to cloud formation since the moisture in the bottle from the water collects smoke particles which form into clouds. In the sky water molecules cling onto solid particles.…
Journey is the act of moving from one place to another, even though most journeys seem physical; many people who embark on a physical journey may also experience an inner journey themself. Ivan Sen’s Beneath Clouds is about two indigenous teenagers who embark on a journey to find more about themselves. Vaughn and Lena both embarks on a journey to find their parents. Vaughn and Lena goes a journey to find their parents. The main themes of Beneath Clouds are Family, friends and racism.…
You are a science teacher planning a lesson on monitoring changes in temperature. Given lab equipment, a thermometer and three cups of water at different temperatures, students will be able to record the temperatures on a graph with 80% accuracy.…
By combining Boyle’s Law, Charles’ Law and Avogadro’s Law, the General Gas Law (or ideal gas law) is proposed. It reveals the relationship between the three properties of a gas, which is pressure, volume and temperature, in a container. It states:…
Procedure: First a 400mL beaker was filled 2/3 full with ice. Next the time and temperature were recorded every minute for 18 minutes. All the data was recorded in a data table. Next the beaker was put on a hot plate and the temperature was taken and recorded every 30 seconds. Then the water was left to continue boiling for 5 more minutes and time and temperature were recorded every 30 seconds. Finally a graph of time and temperature was made.…
In the cloud point experiment, waxes will appear and thickens the oil and clogs fuel filter and injectors in engines. The wax also accumulates on the cold surfaces and forms an emulsion with water. The appearances of cloud point determine the first cloud of wax crystals in a liquid when it is cooled.…
