When heating a container containing a liquid, it is possible to observe the expansion of the liquid, which occupies more volume. What is the name of the coefficient that measures the volumetric expansion of liquids?

The total expansion of a liquid is given by the difference between the expansion of the container that contains that liquid and the so-called apparent expansion.

only statements i, ii, and iv are correct.

In an experiment conducted in the Physics laboratory, students had three cylindrical objects A, B, and C, of the same weight but made of different materials. The three were placed in a container with water. The students observed that object A was floating with 3/4 of its volume immersed, while object B floated completely submerged. Object C was floating with 20% of its volume emerged. Based on this information, we can affirm that:

When heating a glass container containing a common liquid, such as water, it is possible to observe a variation in its volume. This variation occurs due to the thermal expansion phenomenon of the liquid. Considering that the volumetric expansion coefficient of water is approximately 2.1x, what will be the volume variation of a glass bottle with a capacity of 500 mL, completely filled with water, when heated from 20°C to 40°C?

A glass jar contains 200 ml of water at room temperature of 25 °C. On a summer day, the temperature rises to 35 °C and there is no change in the water level inside the container. What is a possible explanation for this phenomenon?
