When a system is taken from state ' a ' to state ' c ' along a path abc , it is found that Q =80 cal and W =35 cal . Along path adc, Q =65 cal the work done W along path adc is
Options
- A20 cal .
- B45 cal .
- C35 cal .
- D65 cal .
Correct answer
A. 20 cal .
Step-by-step solution
For both the paths, U remains same. For path abc: U = Q - W =80-35=45 cal For path adc : U=45 cal and Q=65 cal W = Q - U =65-45=20 cal
