Thermodynamics

Question 1

Internal energy

Answer 1

The sum of random distribution of kinetic and potential energies within a system of molecules

Question 2

Change in internal energy

Answer 2

^U=32/k^T

Question 3

Workdone by a gas

Answer 3

Whenever it expands
W=p^v
F=pa
W=fd
W=p^v
-ve value for workdone by gas

Question 4

First law of thermodynamics

Answer 4

The increase in internal energy = energy supplied by heating + the work done on the system

Question 5

First law of thermodynamics equation

Answer 5

^U= q + W
