1. Elaborar uma proposta de intervenção visando baixar a temperatura das salas de aula da escola e/ou de outros ambientes nos quais você convive (casa, cozinha, quarto, trabalho, etc.). Essa proposta deve levar em consideração os conhecimentos adquiridos sobre os processos de propagação de calor.

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg·k, and 20 w/m·k.
