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.
Assuming they are the same or similar shape and volume, water in glass would freeze first, then plastic then foam. Foam allows transfer of heat out of water more slowly than plastic and the glass probably has the highest rate of heat radiation of the three. 3 people found this useful.
