Answer:
Explanation:
The efficiency of a refrigerator is defined in the terms of coefficient of performance (COP).
The ratio of amount of heat in cold reservoir to the work done is termed as the COP.
COP = QL / W
COP = T2 / (T1 - T2)
Where, T1 be the temperature of hot reservoir, T2 be the temperature of cold reservoir.

Answer:
11
Explanation:
According to Boyle's law:

Thus,

Where, n is the number of the balloons
From the question, it is given that:
For balloon:
P =
Pa
V = 0.040 m³
For cylinder:
P =
Pa
V = 0.0031 m³
So,

n = 11.625
<u>So, Maximum number of balloons = 11</u>
