During an adiabatic process an object does 100 J of work and its temperature decreases by 5K. During another process it does 25 J of work and its temperature decreases by 5K. Its heat capacity for 2nd process is:. a. 20J/K
b. 24J/K
c. 15J/K
d. 100/K

(C) the heat capacity for 2nd process is 15 J/K.

Explanation:

Given;

work, W = 100 J

change in temperature, = -5 K

For the first process;

dQ = dU + dW

for adiabatic process, dQ = 0

0 = dU + dW

dU = - dW

dU = -100 (This remains the same for the second process).

For the second process;

Let C be the heat capacity for 2nd process.

C (dT) = dU' + dW'

dU' = dU = -100

W' = 25

dT = -5 (decrease in temperature)

C(-5) = -100 + 25

-5C = -75

C = -75 / -5

C = 15 J/K.

Therefore, the heat capacity for 2nd process is 15 J/K.

im not to sure what it is

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

happy to
