This experiment is to see if water flows faster out of a smaller can or a larger can. You will need: • two cans (one quite small like a soup can and the other large, like a juice, can.)Follow these steps: A. Remove the top of each can. Punch a hole in the side of each can, very close to the bottom, making sure the holes are equal in size. Cover each hole with a piece of tape, and place the cans next to the sink.B. Put water in both cans, making sure the water is at the same level - different amounts, but the same level. Turn the cans so the holes are facing into the sink, and remove the tape at the same time. Answer these questions: Do the streams of water shoot out at the same distance? Why or why not?C. Try the same experiment, but this time put one cup of water in each can. What happens to the streams of water now?D. Try the same experiment, but this time fill both cans to the top. What happens to the streams of water?ANSWER A B C AND D CORRECTLY!!!

Answers

1) How are particles in motion and temperature related?

Temperature is the measure of heat. The kinetic energy of particles in motion is determined by the temperature. The higher the temperature, the higher the kinetic energy of the particles (basically, the hotter it is the faster the particles move).

2) How does a thermometer work?

A thermometer measures the average kinetic energy of the particles around the thermometer. As seen in 1), the kinetic energy defines the temperature, so measuring the energy of the particles can show you the temperature of the object.

3) What are temperature scales, list them and give examples.

Temperature scales are pretty much systems with which we compare different temperatures. The three widely used temperature scales today are Fahrenheit, Celsius, and Kelvin. All three are used in different countries and mainly for different purposes. Fahrenheit is used only in the United States and a few other countries around the world, while Celsius is excepted by nearly the entire rest of the world. Kelvin is used primarily in the scientific setting.

4) Define volume.

Volume is pretty much the amount of three-dimensional space an object or substance takes up. For example, a liter is a unit of measurement of volume. A two-liter bottle of soda means it contains the amount of soda that fills up 2-liters worth of three-dimensional space.

A bicycle traveled 150 meters west from point A to point B. Then it took the same route and came back to point A. It took a total of 2 minutes for the bicycle to return to point A. What is the average speed and average velocity of the bicycle?

Answers

Answer:

2.5 m/s

0 m/s

Explanation:

Average speed is distance over time.

Average velocity is displacement over time.

The bicycle travels 150 meters from A to B, then 150 meters from B to A. So the distance is 300 meters and the displacement is 0 m.

s = 300 m / 120 s = 2.5 m/s

v = 0 m / 120 s = 0 m/s
