A fine copper wire(0.07-cm diameter) is initially heated to 175C. The wire is suddenly exposed to an environment at 40C with a heat-transfer coefficient of 60W/(m^2*C).

Determine(a) the wire temperature and (b) the heat loss per unit length(W/m) 10s after the wire is exposed tot he convective enviroment.
