The pin configuration of the 240 volt receptacle is different from a 120 volt pin configuration. This is a safety factor to prevent the wrong voltage being applied to the wrong devices.
yes but it will not be as good eg if it is a phone charger it will take longer to charge
Only use 110-120 volt appliances on a 110 volt socket.
can you plug a 115 volt into a 110 volt
You plug the appliance into the outlet. Israel uses 220-volt household current. Any 110-volt appliances brought from abroad will need a small transformer, which can be bought in appliance stores.
NO

Yes.

Yes you can - with a transformer. Maplin Electronics sell a converter that allows you to plug appliances that run on 110V into the normal UK mains. See the related.
no
Yes you can. Most electrical appliances will work if supplied with power that's within 10% of their voltage rating.
