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.
Circulating air can transfer heat from one side of the room to another; thatâs convection. But out in the vacuum of space, the only way heat can transfer is radiation. Photons of energy get absorbed by an object, warming it up. At the same time, photons are radiating away. If the object is absorbing more photons than it emits, it heats up.
