the heat is used to BREAK BONDS between molecules in order t chnage state .It is not used to give kinteic energy to molecules therfore doesnt heat the molecules up and no temp rise

18- C??? best for convectional currents if u dotn kno ask

for the circuit to be complete, the current shud move from positive, through all the lamps, lastly through D, and to the negative.

If D breaks, the circuit isnt complete.

ok u know it has to be smewhere low for the warm air to rise and spread all over. the only two low points are D and C. answer is C because from C, there is a path for the warm air  to rise...it can also spread horizontally and spread.
