It will accelerate unless it is acted on by an equal and opposite force.

I can push on a pallet of rice but because of friction causing an equal and opposite force it will not move.

if a force is applies to an object, there must be a transfer of energy which normally involves addition or subtraction of kinetic energy.  In an ideal system with no other forces acting on the object, the object must change velocity ("accelerate") if a force is applied to it.

The statement is correct as far as it goes.  Sometimes, internal forces offset the applied external force and the transfer of energy is via heating of the object.  Heat, as represented by change in temperature, is a change in motion of (some of) the components of the object even if the totality of the object does not move.  Excited atoms display acceleration, which is not quite the same thing as the object accelerating.

"If a single force acts, on an object, the object will accelerate".  The adjectival phrases "acts on an object" is a qualifier and must be both preceded by a comma and terminated by one.  The physics of the statement is correct.  It is the corollary to Newtons first law.  Which is effectively that a body will NOT accelerate unless acted upon by a force.

I would probably say:

''If a net force acts on an object, the object accelerates in the direction of the net force''
