Copper doesn't react with dilute sulphuric acid as its reduction potential is higher than that of hydrogen and so it cannot displace hydrogen from non-oxidising dilute H2SO4.
But, if we add concentrated sulphuric acid and heat the copper, a redox reaction occurs and the acid gets reduced to sulphur dioxide.
Cu + 2H2SO4 = CuSO4 + SO2 + 2H2O
