How can dry ice spray be used effectively for cleaning and disinfecting surfaces?
Dry ice spray can be used effectively for cleaning and disinfecting surfaces by rapidly freezing and killing bacteria and viruses upon contact. The extreme cold temperature of the dry ice can penetrate cracks and crevices, making it a thorough and efficient cleaning method. Additionally, the dry ice sublimates, leaving behind no residue or moisture, making it ideal for sensitive equipment or areas where traditional cleaning methods may not be suitable.
What is really slippery?
Ice and oil are both substances known for being very slippery. Their smooth surfaces reduce friction between objects, causing them to slide easily.
What are some creative ways to make refreshing summer treats using dry ice, such as dry ice popsicles?
One creative way to make refreshing summer treats using dry ice is to create dry ice popsicles. To do this, mix your favorite fruit juice or soda with chunks of dry ice in a mold. The carbonation from the dry ice will create a fizzy and refreshing popsicle. Another idea is to make a dry ice ice cream by mixing cream, sugar, and flavorings with dry ice in a bowl. The dry ice will freeze the mixture quickly, creating a creamy and smooth ice cream. Just be sure to handle dry ice carefully and follow safety precautions when using it in food preparation.
Why is dry ice called so?
Dry ice is called so because it consists of solid carbon dioxide, rather than water ice. When dry ice melts, it sublimates directly into carbon dioxide gas, without leaving a liquid residue, which is why it is termed as "dry" ice.
What is ratio od dry ice volume to mass?
The ratio of dry ice volume to mass depends on the temperature at which the dry ice is stored, as dry ice sublimes at -78.5°C. At this temperature, the volume of dry ice is about 832 cm³ per 1 kg of mass. Keep in mind that this ratio may vary slightly due to factors such as pressure and purity of the dry ice.
When solid surfaces slide over each other what is the kind of friction that occurs?
The kind of friction that occurs when solid surfaces slide over each other is called kinetic friction. It is the resistance between the surfaces that are in motion relative to each other.
What types o surfaces have the least amount of friction and why?
Surfaces with low friction include ice and lubricated surfaces. Ice has low friction due to its molecular structure and lack of adhesion properties with other surfaces. Lubricated surfaces reduce friction by providing a slippery layer between two surfaces, allowing them to slide more easily.
What surfaces don't have much friction?
Surfaces that have low friction include ice, lubricated surfaces, polished metals, and certain plastics like Teflon. These surfaces allow objects to slide easily across them due to minimal resistance.
Would the pebble tech in your pool get messed up from dry ice?
Dry ice can damage pebble tech surfaces in pools due to its extreme cold temperatures. The rapid temperature change can cause the surface to crack or delaminate. It is best to avoid direct contact between dry ice and pebble tech surfaces to prevent any potential damage.
Is friction high or low on ice?
Friction is low on ice because ice has a very smooth surface, which reduces the amount of friction generated when objects slide across it. This is why it can be challenging to walk or drive on icy surfaces compared to other surfaces with higher friction.
Why does ice often form on he outside of a glass beaker containing dry ice?
A beaker of Dry Ice will have VERY cold, glass walls. The moisture in the surrounding air comes into contact with the cold surfaces, condenses and freezes on them. Thus, your ice formation on the beaker.

What are surfaces with very little friction?
Surfaces with very little friction include ice, polished metal surfaces, and Teflon-coated surfaces. These surfaces reduce friction because they have smooth textures or surface coatings that allow objects to slide over them with minimal resistance.
How do penguins walk on the ice?
They waddle. Sometimes, they fall onto their stomachs and slide.
What is an example of low friction?
Ice sliding on ice is an example of low friction because the smooth surfaces of the ice reduce the resistance between the two objects, allowing them to slide easily over each other with minimal force.
What is solid CO2 called?
a molecular solid...
