Q1: Which of the following expressions defines the Baume gravity scale for liquids lighter than water ?

ANS:A - °Be = (140/G) - 130

The expression °𝐵𝑒=140𝐺−130°Be=G140​−130 doesn't represent the Baume gravity scale formula typically used for liquids lighter than water. However, let's break down this expression:

• °𝐵𝑒°Be represents the Baume gravity scale reading.
• 𝐺G represents the specific gravity of the liquid.

In this expression, 140 is a constant term and 130 is another constant term. When 𝐺G increases, the value of 140𝐺G140​ decreases. Subtracting 130 from this result would generally reduce the value further. This expression seems to suggest a scale where the Baume reading decreases as the specific gravity of the liquid increases. However, it does not align with the traditional Baume gravity scale formula for liquids lighter than water, which is typically expressed as °𝐵𝑒=145−145𝐺°Be=145−G145​. If this expression is used in a different context or for a different purpose, it would be important to understand the specific interpretation and basis behind it.
