As kerosene is less dense than water so level of kerosene will fall
If you add an equal amount of salt to the beaker on the left, the water level in that beaker will rise slightly due to the displacement caused by the added salt. In contrast, the water level in the beaker on the right, which has no added salt, will remain unchanged. The overall increase in water level in the left beaker is a result of the combined volume of the water and the salt.

To determine the mass of the beaker and fluid on a triple beam balance, you would first place the beaker filled with the fluid on the balance. Then, you adjust the sliders on the beams until the balance is level, indicating that the total mass is equal to the sum of the beaker's mass and the fluid's mass. The reading on the balance will give you the combined mass of both the beaker and the fluid. If you need the mass of each separately, you can weigh the empty beaker first and then subtract that mass from the total.
"definetly not it sould be clear" Sorry friend, you're wrong. Kerosene can be either dyed red, most often in bulk containers, or clear. The clear Kerosene has a higher federal tax than the died. It doesnt matter the color, red or clear.
The starting line is above the water level in the beaker to ensure that the measurement of liquid volume is accurate and consistent. This positioning allows for a clear distinction between the meniscus of the liquid and the starting mark, reducing the risk of parallax error when reading the scale. Additionally, it ensures that any variations in liquid surface tension or evaporation do not affect the initial measurement.
The density of the object is at least equal to, and possibly greater than, the density of the liquid in the beaker.

Ice expands as it freezes, so it takes up more volume than an equal mass of water. Hence when the ice melts in the kerosene, the liquid water takes up less volume, so the level of the kerosene drops.
ill tell you if you tell me how you complete level 7
Kerosene is soluble in iodine because both are nonpolar molecules. Nonpolar substances tend to dissolve in each other because they have similar intermolecular forces, such as London dispersion forces. This allows kerosene and iodine to mix together at the molecular level.
To raise the water level in the beaker, you should add more water to it. The amount of water added should be equal to the volume you want the water level to increase by.
in beaker the substance that contains is largely transpearable ,but in pippette the substance tat contain is transparable only drop-wise
Desalination
Yes, ozone levels have dropped. It is because of use of CFC's by humans.
not sure... I am REALLY stuck too!
Graduation marks on a beaker are the lines or measurements used to indicate volume or level of liquid inside the beaker. They help in accurately measuring the amount of liquid being poured or mixed in the beaker.
