Physics : Mechanical Physics Of Heat Experiment

In the lab we filled the first beaker up with water. Then we took a pipet (filled with the liquid) and dropped water droplets onto the

Step 3: Use the thermometer to identify and record the temperature for room temperature, in your refrigerator, in your freezer, and then research the temperature of boiling water (do not take this temperature) and record them in Table 2.

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

2. Determine the room’s air temperature, and also measure the diameter of the glass tube. Record the data.

Drill a hole relatively larger than the thermometer in the lid of one of the jars. Only one lid needs to have a hole because the jars will be tested separately.

The control experiment for this investigation will be the experimental setup of 5 trials using 5oC as the temperature. All the steps in the method will be followed.

9) Trial E: Remove the syringe and empty the beaker. Add a Thermometer to the beaker. Add 200 mL of Room Temperature water to the beaker and heat with a Bunsen Burner until it reaches 100° C. Remove the Bunsen Burner. Repeat Steps 5 & 6.

To begin the experiment, students first obtain a LabQuest with a temperature probe. First, you retrieve about 20gs of t-butyl alcohol and put it in a pre-massed test tube. Students then prepare one beaker with ice water and another beaker with warm water. Students will first put the t-butyl alcohol into warm water to prevent it from freezing in room temperature, and put the temperature probe in the test tube. Afterwards, students will place the test tube containing the t-butyl alcohol and put it in the ice water until the temperature begins to

Procedure: This lab starts off by making sure the logger pro and temperature probe are in proper condition. Then, the data collection must be adjusted to 15 minutes and 12 samples/ min. After that a Bunsen burner must be set up by assembling a ring-stand, ring, and wire gauze, and a crack-less beaker is used to boil some water. First the beaker and the large watch glass need to be weighed and the mass has to be recorded using a triple beam balance. Next, the beaker with 200g of ice is placed on the ring stand, and immediately heated over medium flame. An important note is to make sure the flame is perfectly adjusted so the ice does not melt on the counter while trying to adjust the flame. Furthermore, place the temperature probe in the ice so it is not resting at the bottom of the beaker, it is best to secure it with a small clamp. Additionally, click the green start button on the computer and stir continuously with a glass rod until the ice is completely melted. Once the ice has melted which is somewhere between 3-5 minutes, the stirring rate will slow

Submerge the graduated cylinder in the plastic tub so that it is completely filled with water. Hold the open end of the graduated cylinder and move it vertically upside-down where the open end of the graduated cylinder is still submerged in the plastic tub. Clamp the graduated cylinder the ring stand of the lab table to keep it in place. perforate a hole in the top of the rubber cork for the solution container. Cut a straw the length of about four inches. place the straw inside of the rubber cork hole. Set up your timer for two minutes.

14. Note the height of the water in the tube. 15. Record the time the tube was

Start the magnetic stirrer and the timer at the same time and measure the temperature at 30 second intervals for 2.5 minutes.

Then pour 1/3 of the bottle’s volume of water back into the bottle and mark out the level of it with a pen. (It’s important to only use the bottle once in the experiment as it can be weakened by the explosion and can be dangerous if used again).

Heat is a form of energy that is transferred between two substances at different temperatures. The flow of the energy is from the object of higher temperature to the object of lower temperature. The heat is measured in units of energy, usually calories or joules. Temperature on the other hand, is how cold or hot an object is. The temperature is the average kinetic energy per molecule of a substance. This is measured in degrees on the Celsius or Fahrenheit or in Kelvins.

Rinse the graduated cylinder with some tap water. Then rinse the graduated cylinder with some about 10.0 ml of the 1.0 M HCl. Completely dry the graduated cylinder with a paper towel drying wand. Carefully measure 6.25 ml of the 1.0 M HCl. Leaving the HCl in the graduated cylinder measure the initial temperature of acid. 27.8∘C
