Ice is a solid, whether or not it has air in it
The liquid inside a Galileo thermometer is usually a clear, alcohol-based solution.
A solution is a homogeneous mixture composed of two or more substances. It consists of a solvent (the substance that dissolves the solute) and a solute (the substance that is dissolved). The solute particles are evenly distributed and do not settle out.
No, brass is not a homogeneous mixture. It is considered a solid solution of copper and zinc, making it a type of alloy. A homogeneous mixture has a uniform composition throughout, whereas brass has distinct copper and zinc atoms mixed at the atomic level.
An unopened can of soda is not a homogeneous solution; it is a mixture. While the liquid inside may appear uniform, it contains dissolved carbon dioxide, sugars, flavorings, and other ingredients that can separate when the can is opened. The carbonation creates bubbles, which are not evenly distributed throughout the liquid. Thus, it is better categorized as a heterogeneous mixture rather than a true homogeneous solution.
Only a hot mixture of the same gases that are in the air you breathe.
No, a fish tank with water inside is not a mechanical mixture. It is a homogeneous mixture because the water and any additives are evenly distributed throughout the tank.
Pond water with microscopic organisms is considered a mixture. It is a combination of different substances, including water, dissolved minerals, gases, and living organisms. The presence of multiple components in varying proportions makes it a mixture rather than a pure substance.
yes, it is because you can see the bubbles inside the tea so there is two substances inside so it's a mechanical mixture. yes, it is because you can see the bubbles inside the tea so there is two substances inside so it's a mechanical mixture. yes, it is because you can see the bubbles inside the tea so there is two substances inside so it's a mechanical mixture.
You can use a mixture of warm water and mild dish soap to clean the inside of your fridge. Wipe down all surfaces with this solution and then dry them thoroughly. Remember to remove all food items before cleaning.
To break open the cheek cells and release DNA from inside them, a detergent is added to the Gatorade and saliva mixture. The detergent disrupts the cell membranes, allowing the DNA to be released into the solution. This process helps to isolate the DNA for further analysis or experimentation.
The meat is usually considered the best part. In some fruits, the inside is the best part (like pomegranates), and are thus called "meat."
When a cell is in a solution that has the same concentration of water and solutes, it is considered isotonic. Water still moves through the plasma membrane, but water enters and leaves the cell at an equal rate-it has reached an equilibrium, and there is no net movement of water.
