Viral meningitis: Meningitis caused by many viruses is usually contagious. However, certain viruses that are transmitted by mosquitoes are usually not spread person to person, so they are not contagious.
3] Heat transfers through the glass by conduction 4] Heat transfers from the glass to the outside air via convection. If the temperature differences are small and there are no winds or drafts, transfer of heat to/from air/glass will be by conduction.
It is water that condenses out of the air. When moisture-laden warmer air comes into contact with the cold surface of the glass, the glass absorbs heat from the air, and â¦ if conditions are right it absorbs the heat that has maintained the water as vapor.
