      密度计越往下密度越大吗,请问为什么密度计上越往下密度值越大?

      据和记百科网站「柚花离海」消息,近日,密度计越往下密度越大吗,请问为什么密度计上越往下密度值越大?引发热议,为什么密度计上越往下密度值越大同样引起许多争议,对此众网友各抒己见。但到底是怎么回事呢?和记百科为您解答。

      

    密度计越往下密度越大吗

     

      密度计越往下密度越大。密度计所受到的浮力等于物体排开液体的重力,而密度计的重力是保持不变的,因此当密度计放入被测液体中时,其浮力也保持不变。当密度计浸入液体部分减小时,即V排减小,而浮力保持不变,因此ρ液增大。

      密度计分类:

      按照密度计的应用场景不同,可以将密度计分为台式密度计和便携式密度计。

      按测量的物质形态不同,可以将密度计分为固体密度计、液体密度计和气体密度计。

      按照工作原理的不同,可以将密度计分为静压式、振动式、浮子式和放射性同位素式等类型的密度计。

      问题:

      正确答案:

      

      【英文介绍/For English】:

      

      The further down the densitometer goes, the higher the density. The buoyancy of the density meter is equal to the gravity of the object to displace the liquid, and the gravity of the density meter remains unchanged, so when the density meter is placed in the liquid to be measured, its buoyancy also remains unchanged. When the part of the density meter immersed in the liquid decreases, that is, the V row decreases, while the buoyancy remains unchanged, so the ρ liquid increases.

      Density meter classification:

      According to different application scenarios of density meters, density meters can be divided into desktop density meters and portable density meters.

      According to the different forms of substances measured, density meters can be divided into solid density meters, liquid density meters and gas density meters.

      According to different working principles, densitometers can be divided into static pressure type, vibration type, float type and radioisotope type and other types of density meters.
