Abstract
The utility model belongs to counters and particularly relates to a counter for measuring the molecular diameter through an oil film method. The counter comprises a bottom surface (1); square containers (2) are distributed on the bottom surface (1); both the bottom surface (1) and the square containers (2) are made of a transparent material; and the side length of the square container (2) is 2 millimeters. The counter has the advantages of simple structure, convenience and practicability.
Description
Technical field
The utility model belongs to counter, and particularly a kind of oil film method is surveyed molecular diameter and used counter.
Background technology
With the size of oil film method estimation molecular diameter is to utilize the measurement of macroscopic quantity to obtain the experiment of the size of microscopic quantity in the physics experiments of high school, significant to the understanding that improves student's microworld.During experiment, when oleic acid molecular after forming thin layer on the water surface, on thin layer, cover a transparent graph paper, the grid of forming by coordinate line that the number thin layers are shared.This method, when the number grid, most easily or leakage number.
The utility model content
The purpose of the utility model provides a kind of oil film method survey molecular diameter and uses counter.
The scheme that the utility model solve the technical problem is: a kind of oil film method is surveyed molecular diameter and is used counter, comprises the bottom surface, spreads all over square container on the bottom surface, and bottom surface and square container are processed by transparent material.
As further technical scheme, the length of side of said square container is 2 millimeters.
During experiment, after oil film forms, be placed on this counter above the oil film; Along the edge of oil film, in the residing square container in oil film edge, drip colored liquid, be described in the periphery of oil film on the counter with colored liquid; The number while dripping can or not omitted by majority yet.After the square container that is fenced up by colored liquid can be taken out the water surface, slowly carefully count.
In sum, the utlity model has simple in structure, convenient and practical advantage.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the enlarged drawing of the utility model at the oil film place.
Embodiment
Like Fig. 1, shown in Figure 2, a kind of oil film method is surveyed molecular diameter and use counter, comprises bottom surface 1, spreads all over square container 2 on the bottom surface 1, and the length of side of square container 2 is 2 millimeters, and bottom surface 1 and square container 2 are processed by transparent material.During use, this counter is placed on the oil film 3 gets final product.
Claims (2)
1. an oil film method is surveyed molecular diameter and is used counter, and it is characterized in that: comprise bottom surface (1), spread all over square container (2) on bottom surface (1), bottom surface (1) and square container (2) are processed by transparent material.
2. a kind of oil film method as claimed in claim 1 is surveyed molecular diameter and is used counter, and it is characterized in that: the length of side of said square container (2) is 2 millimeters.
