What else can I help you with?
Why was it important not to let the thermometer rest on the bottom of the breaker?
It is important not to let the thermometer rest on the bottom of the beaker because the bottom can be heated unevenly leading to inaccurate temperature readings. Placing the thermometer in the liquid away from the bottom ensures a more accurate measurement of the liquid's temperature.
What liquid has highest density?
Mercury has the highest known liquid density at room temperature, which is about 13.6 times denser than water.
How and why would you use a beaker to measure the density of an object?
A beaker filled with liquid can be used to measure the volume of a non-soluble solid, or of a liquid. If the mass of the solid or liquid sample has been previously determined, the liquid (usually water) displaced from a filled beaker will provide the volume of the sample. Mass divided by volume gives the density. One of the early uses of the process was to identify counterfeit gold coins. In order to weigh the same as real gold coins, fakes would have to be thicker, and therefore have greater volume.
The image below shows a jar containing four different liquids, each a different color The liquids do not mix, so the colors remain separate Which of these liquids has a density greater than that of?
red clear blue
Where should a thermometer be placed in a beaker?
Hold it by the top or use a clamp. But make sure before you take the temperature you stir the liquid around in the beaker first and that you do not let it touch the bottom of the beaker as the glass will be hotter than your liquid.
What happens when an object is dropped into a beaker containing a liquid and then the object drops to the bottom of the beaker?
The density of the object is at least equal to, and possibly greater than, the density of the liquid in the beaker.
If a liquid is added to a beaker the pressure exerted by the liquid on the bottom of the beaker?
increases due to the increased weight of the liquid. This is because the liquid's weight creates a force that is spread out over the bottom of the beaker, leading to an increase in pressure.
How is density of a liquid measured?
The density of a liquid can be measured with a beaker. the beaker is weighed alone, then a specific measured volume of the liquid is placed in the beaker and the beaker is reweighed. The difference between the beaker with and without the water is noted. from there the mass of the liquid for the specific volume is then known. using hte formula d = m/v, we can therefore determine the density. where m is in kg and v is in liters.
How can you locate the densest liquid?
You can determine the density of a liquid by measuring its mass and volume, then calculating the density using the formula density = mass/volume. The liquid with the highest density will sink to the bottom when layered with other liquids of different densities in a container.
Why is it important to have the bulb of a thermometer submerged in liquid without touching the sides or bottom of the beaker?
The sides or bottom of the beaker will likely be at a significantly different temperature than the liquid.
Why is it not allowed to let the bulb of the temperature touch the bottom nor sides of the beaker that contains your liquid measuring the temperature?
The bottom and sides of the beaker will be hotter than the liquid inside.

It is important not to let the thermometer rest on the bottom of the beaker because the bottom can be heated unevenly leading to inaccurate temperature readings. Placing the thermometer in the liquid away from the bottom ensures a more accurate measurement of the liquid's temperature.
How do you make a device that measure the density of a liquid?
Density = mass/volume, so weigh a beaker, put your liquid in the beaker, weigh both beaker and liquid. With subtraction, find the weight of the liquid. Then, find the volume of the liquid with a graduated cylinder. Take mass/volume to find your density.
Will the liquid on the top have the highest or lowest density?
The floating liquid will have a lower density than the liquid it is floating on.
What liquid has highest density?
Mercury has the highest known liquid density at room temperature, which is about 13.6 times denser than water.
Three different liquids and two equal sized cubes are placed in a beaker which of the objects has the greater buoyant force acting on it?
The cube in the liquid with the highest density will experience the greatest buoyant force. Buoyant force is determined by the density of the fluid displaced by the object, so the denser the liquid, the greater the buoyant force.
