1. The problem statement, all variables and given/known data A silicon electric circuit is 23 mg, when electricity flows through the circuit rising the energy by 7.4 mW but this circuit wasn't design for heat ventilation. Find the rate of how much the temperature is rising per second ( ΔT/Δt ) The specific heat of silicon is 705 J/kg.K 2. Relevant equations Q=mcΔT 3. The attempt at a solution I know that when the electricity flows through the circuit, it will rise the temperature and we can figure the change in temperature by find both initial and final temperature but what about time? how this factor get in the calculation?
