Answer:
288.2 K
Explanation:
= Volumetric expansion coefficient =
= Initial temperature = 273.1 K
= Final temperature
= Original volume = 150 mL
Change in volume is given by
The temperature of the ethyl alcohol should be 288.2 K to reach 150 mL
Answer
given,
high temperature reservoir (T_c)= 464 K
efficiency of reservoir (ε)= 25 %
temperature to decrease = ?
increase in efficiency = 42 %
now, using equation
T_C = 348 K
now,
if the efficiency is equal to 42$ = 0.42
