If you know that the change in entropy of a system where heat was added is 12 j/k, and that the temperature of the system is 250 k, what is the amount of heat added to the system? a)-5j b)-125j c)- 600 j d)-5000 j e)-8000 j

Solution:

Given:

Change in entropy of the system, ΔS = 12J/K

Temperature of the system, = 250K

Now, we know that the change in entropy of a system is given by the formula:

ΔS =

Amount of heat added, ΔQ =

ΔQ = 3000J

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
