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.
On average, a fraction of the molecules in a glass of water have enough heat energy to escape from the liquid. Water molecules from the air enter the water in the glass, but as long as the relative humidity of the air in contact is less than 100% (saturation), the net transfer of water molecules will be to the air.
