So that the temperature of the liquid is at a constant measurement
If left in a beaker for a while, water can gradually evaporate due to exposure to air, especially under warm conditions. This may result in a decrease in the water level in the beaker. If the beaker is left uncovered, impurities from the air or container may also potentially contaminate the water over time.
The students should not use the beaker with the crack as it poses a risk of breaking further while pouring water, potentially causing injury. They should find a different beaker that is intact and safe to use for their experiment.
1. Never heat alcohol directly on naked flame 2. you should take a beaker with boiled water in it and then place the alcohol with the test tube in it 3. you should wear goggles while heating alcohol. 4. never smell the alcohol directly after heating
The volume of wax increases when heated because it expands due to the heat causing its molecules to move faster and spread apart. In contrast, the volume of water reduces when heated as it transitions from a liquid to a gas (steam), which results in decreased volume due to the increased distance between water molecules.
A graduated beaker has markings on the side to measure volume accurately, while a regular beaker does not have these markings. Graduated beakers are typically used when precise volume measurements are needed, while regular beakers are used for general mixing and holding liquids.

It evaporated.
The volume of the water in Beaker X will be 100cm3, as you are not adding any more water to the equation (50X+100Y is not 150Y or X, but 50X+100Y) The total volume of matter in Beaker X will be 150cm3, and if the beaker is labelled, the volume measure will indicate 150cm3 due to the displacement of water. But as the answer to your question, the volume of water in Beaker X must be 100cm3 even though visual indicators will not show this due to the displacement of water by marbles
no
If you left water in an open container for several days in summer, the water would eventually evaporate and there would be less water than you put before but if you put in in winter, the water would eventually freeze.

The hot saltwater will cause the potato cube to absorb the water due to osmosis, while the cold saltwater will cause the potato cube to release water. The difference in temperature affects the rate of osmosis – higher temperatures increase the rate, while colder temperatures decrease it.
The capacity of a beaker can vary widely depending on its size and design, but common laboratory beakers typically range from 50 milliliters to 2 liters. Smaller beakers may hold around 100-250 milliliters, while larger ones can accommodate several liters. It's important to check the markings on the specific beaker to determine its maximum volume.
The addition of sugar to Beaker B lowered the freezing point of the water, while the addition of salt to Beaker C also lowered the freezing point of the water. This is because both sugar and salt act as solutes that disrupt the formation of ice crystals and reduce the freezing point of the solution.
