1 (Heat and its transferring)
1- Bring a beaker contains small amount of water, then record the temperature of water . 2- Heat a group of metal
balls by using boiler , then record the temperature of the balls . 3- Fall the hot balls in the water , and record the temperature of the water and the balls together . 4- What is your observations ........... Conclusion: Activity
2 (Movement of the particles and temperature)
1. Put some identical spheres made of metal in a plastic cup then determine the spheres temperature first. 2. Place another identical cup above the first one so that they are tightly together as in figure. 3. Invert the positions of the two cups upside down from 20 to 30 times then determine temperature at the end.
