Answer:

4.Clean Regularly

Cleaning with a household cleaner that contains soap or detergent reduces the amount of germs on surfaces and decreases risk of infection from surfaces. In most situations, cleaning alone removes most virus particles on surfaces. Disinfection to reduce transmission of COVID-19 at home is likely not needed unless someone in your home is sick or if someone who is positive for COVID-19 has been in your home within the last 24 hours.

When and how to clean surfaces in your home

¤ Clean high-touch surfaces regularly (for example, daily) and after you have visitors in your home.

¤ Focus on high-touch surfaces such as doorknobs, tables, handles, light switches, and countertops.

¤ Clean other surfaces in your home when they are visibly dirty or as needed. Clean them more frequently if people in your household are more likely to get very sick from COVID-19. You might also choose to disinfect.

¤ Clean surfaces using a product suitable for each surface, following instructions on the product label.

5. Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.
