I. Introduction A. Purpose: The purpose of this experiment is to determine whether the distance between substances affects the time required for material to reach thermal equilibrium. B. Assumption: As the distance between the substances becomes shorter, the time required for the material to reach thermal equilibrium becomes shorter. C. Scientific concept: Measurement of thermal equilibrium of temperature - molecular motion - Kinetic energy - kinetic energy - energy when two substances are at the same temperature - energy reaches thermal equilibrium from higher temperature materials to lower temperature materials Time to take.

This is true through the process of evolution, which explains why some research is so frustrating that it duplicates. Experiments conducted in a laboratory using the same kind of animal and the same food, regardless of how carefully the experiment was made the same, had no effect in other laboratories. Perhaps the only difference is that there is a geographically specific virus lurking in a certain place. This is enough to activate a series of reactions that invalidate the experiment. It hurts

We can not manage the world outside the laboratory. Background is very important. Special preferences may be important. The previous experience may be important The specification of the group may be important. I tried to eliminate all the factors in the laboratory to determine the causal relationship of only one variable in the result. It may be important outside the laboratory. You may have determined the causal relationship between variables and behavior, but that is the result. However, the relationships and different backgrounds between different individuals and at different times between us and us may differ. . Other factors may affect the strength of the causal relationship

I can not even tell you if I sent two nearly identical gems to Gem Lab and got two different levels. In this respect, I sent the same stone twice to the laboratory many times and got different results from different jewelry scholars! The problem of relying on certificates is that it is subjective. At the end of the day, this is the opinion of the laboratory staff. You can score the same stone in different ways from different laboratories or send the stone back to the same laboratory to get another level different from laboratory different scoring on another day I will.
