Answer:
The answer to your question is 33.4 ml
Explanation:
Data
volume 1 = V1 = 42 ml
temperature 1 = T1 = 20°C
temperature 2 = T2 = -60°C
Volume 2 = V2 = x
Process
1.- Convert celsius to kelvin
T1 = 20 + 273 = 293°K
T2 = -60 + 273 = 233°K
2.- Use the Charles' law to solve this problem
Solve for V2
V2 =
3.- Substitution
V2 =
4.- Simplification
V2 =
5.- Result
V2 = 33.4ml
Explanation:
The given data is as follows.
,
Work produced per kJ of heat extracted from hot reservoir = 0.45 kJ = Efficiency
If the device is Carnot cycle then its efficiency will be maximum and its value will be equal to
Using this relation we will calculate the efficiency as follows.
Efficiency =
=
= 0.928
Hence, it means that this type of device is possible and the claim is also believable.
