Why a heat engine with 100% efficiency can never be realized in practice?

For 100% efficiency T1 = ∞ (or) T2 = 0 k. As absolute zero and infinite temperature cannot be
realized in practice, the efficiency of a heat engine cannot have 100%. The efficiency of a heat
engine is always less than unity.
