Answer:
The temperature coefficient of resistivity for a linear thermistor is
Explanation:
Given that,
Initial temperature = 0.00°C
Resistance = 75.0 Ω
Final temperature = 525°C
Resistance = 275 Ω
We need to calculate the temperature coefficient of resistivity for a linear thermistor
Using formula for a linear thermistor
Put the value into the formula
Hence, The temperature coefficient of resistivity for a linear thermistor is
Answer:
=118.8 K= 154.2°C
Explanation:
COP_max of carnot heat pump=
where T_H and T_C are temperatures of hot and cold reservoirs
Also COP=
in the question
⇒
heat is added directly to be as efficient as via heat pump
and T_H= 24° C= 297 K
on calculating the above equation we get
=118.8 K
the outdoor temperature for efficient addition of heat to interior of home
=118.8 K= 154.2°C
