Air bubbles would make the volume you read in the measuring cylinder increase from the actual volume of theliquid. so when you add in the metal, there would be an increase in the volume of the metal than it really is. the mass of the metal cannot be affected by air bubble because this is the amount of matter in the metal. This increase in volume causes the density of the metal to reduce from its original value. since mass is constant, density is inversely proportional to volume. As volume increases, density decreases.
hope that was helpful.
What else can I help you with?
What were the bubbles in the solution when the metals reacted with acids?
The bubbles observed when a metal reacts with an acid are hydrogen gas bubbles. This is because the metal displaces hydrogen from the acid, resulting in the formation of hydrogen gas. The effervescence or bubbling indicates a chemical reaction is taking place.
How could you identify a pure metal if you a balance a graduated cylinder and a table of densities for metals?
Mass divided by volume, same as it is for anything else. The density of metals ranges from around 500 kg/cubic meter up to around 22000 kg/cubic meter, so if you were hoping for a value ... somewhere in that range, which is a pretty wide range, depending on which specific metal you're talking about.
How does the density of the metal in a crushed can compared with the metals density before the can was crushed?
The density of the metal in a crushed can remains the same as the density of the metal before the can was crushed. While the volume of the can decreases when it is crushed, the mass of the metal remains constant. Therefore, the density, which is mass divided by volume, remains unchanged.
When a piece of zinc metal is carefully placed in a beaker of strong acid bubbles form on the surface of the metal and begin to rise to the surface.?
This reaction is a result of the metal displacing hydrogen ions in the acid, forming hydrogen gas. The bubbles observed are likely the hydrogen gas being released and rising to the surface. This reaction is a common example of a single displacement reaction.
What is the density of a 25 gram piece of metal that has a volume of 10 cm cube?
Density= mass/volume 25/10 = 2.5 g/cm3
A piece of metal was gently lowered into a measuring cylinder containing water.The level of water was at 20 cubic metre mark, what is the volume of metal?
The volume of the metal can be calculated by measuring the volume of water displaced after the metal was placed in the cylinder. If the water level rose to the 25 cubic meter mark after the metal was added, then the volume of the metal is 5 cubic meters.
What mass does metal block displace?
The metal block will displace a volume of water equal to its own volume. By measuring the volume of water displaced, you can then determine the mass of the metal block - as long as you know the density of water (1 gram per cubic centimeter).
How does an air bubble inside a metal ball affect density?
It will increase the total volume, but it will hardly affect total mass. Remember the definition of density as mass / volume.
How does heating or cooling affect metal?
Heating metal can cause it to expand, increasing its volume and potentially altering its shape and strength. Cooling metal can cause it to contract, reducing its volume and potentially making it more brittle. Rapid heating or cooling can also lead to thermal stress and distortions in the metal.
Which tools measure length volume and mass and their units?
-- Length is measured by rulers; they are often wood. -- Volume is measured by measuring cups; they are usually glass. -- Mass is most often measured by a laboratory balance; they are metal.
How could you determine the volume of a metal stapler?
To determine the volume of a metal stapler, you would first need to measure the dimensions of the stapler using a ruler or calipers. Then, you would calculate the volume by multiplying the length, width, and height of the stapler together if it is a simple rectangular prism shape. If the stapler has a more complex shape, you could use the displacement method by submerging it in a known volume of water in a graduated cylinder and measuring the change in water level to find the volume of the stapler.
How would find the mass of a metal cube?
To find the mass of a metal cube, you can use a balance scale. Simply place the cube on the scale, and it will provide the mass directly in grams or kilograms. Alternatively, if you know the density of the metal, you can calculate the mass by measuring the cube's volume (length × width × height) and using the formula: mass = density × volume.
Will the volume of metal decrease if it is heated?
No, the volume of a metal increases as it is heated. It expands.
Why must a metal sample always be dry before its mass or volume is taken?
A wet metal sample can have water molecules attached to its surface, which can affect its mass and volume measurements. Removing water ensures accurate data and prevents errors in calculations.
Which property of a block remains constant when the metal is heated?
Mass
What is one way you measure flavoring?
You can use plastic or metal measuring utensils for measuring flavoring.
What metal has a mass of 35.4 and a volume of 3.11?
A sample of an unknown metal has a mass of 35.4g and a volume of 3.11cm^3. The metal is Lead.
