the total energy of system and the surrounding remains constant
it can be exchanged only
it is the special case of conservation of energy
sign conventions are different for chemistry and physics so it depends on the frame of reference
for now just learn that
physics emphasis on surrounding so everything coming in surrounding is +ve
and chemistry emphasis on system anything comes in system is +ve
