If the room is air tight the heat absorption at constant volume is 1.4 × 10⁶ J and delivers the power of 2KW, the time to provide the energy is _____?
Answer: 700s
Explanation
Time = Energy / Power
Given Energy = 1.4 × 10⁶ J and Power = 2 kW = 2000 W:
Time = (1.4 × 10⁶ J) / (2000 W)
Time = 1.4 × 10⁶ / 2000
= 700 s
