Answer:
Amount of Energy transferred
Explanation:
Given:
Initial volume=V
Initial pressure=P
Final volume=2V
Final pressure=3P
Now w know that the Energy transferred in constant pressure pressure is given by
Now the Energy transferred in constant volume process is given by
The total Energy transferred is given by
Answer:
= 5.74W
=0.27 W
Explanation:
d= 2.6cm =>0.026m (for both the ceramic and the carpet )
Thermal conductivity of wool ''=
=
= 0.04J/(sm °C)
Thermal conducticity of carpet '' = 0.84 J/(sm °C)
Area 'A'= =
= 77.2cm²=> 77.2 x
m²
=33.0°C
=10.0°C
Average Power is determined by dividing amount of energy'Q' by time taken for the transfer't':
= Q/Δt
Due to conductivity, heat of flow rate will be P= dQ/dt
P= =
For CERAMIC:
=
=> [0.84 x 77.2 x
(33-10) ]/0.026
= 5.74W
For WOOL CARPET:
=
=> [0.04 x 77.2 x
(33-10) ]/0.026
=0.27 W
