3. Two identical refrigerators are plugged in for the first time. Refrigerator A is empty (except for air) and refrigerator B is filled with jugs of water. The compressors of both
refrigerators immediately turn on and begin cooling the interiors of the refrigerators.
After 2 hours, the compressor of refrigerator A turns off while the compressor or
refrigerator B continues to run. The next day, the compressor of refrigerator A can be
heard turning on and off every few minutes, while the compressor of refrigerator B
turns on and off every hour or so (and stays on longer each time). Explain these
observations.

Which of the following did you identify correctly

Answer: temperature? i hope this and have a wonderful

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it

This kind of reaction is called a synthesis otherwise known as combination reaction
