Which of the following is true about the sign convention of work done ...
Answer:
The sign convention of work done and heat is an important concept in thermodynamics. It helps us determine the direction of energy flow and whether it is positive or negative.
Heat:
Heat is a form of energy transfer between two systems due to a temperature difference. The sign convention for heat is as follows:
- Heat evolved by the system is considered negative: When heat is released from the system to the surroundings, it is considered negative. This indicates that the system is losing energy.
- Heat taken up by the system is considered positive: When heat is absorbed by the system from the surroundings, it is considered positive. This indicates that the system is gaining energy.
Work:
Work is the energy transfer that occurs due to a force acting through a distance. The sign convention for work is as follows:
- Work done by the system is considered positive: When the system does work on the surroundings, it is considered positive. This indicates that the system is expending energy.
- Work done on the system is considered negative: When work is done on the system by the surroundings, it is considered negative. This indicates that the system is gaining energy.
Explanation:
Based on the given options:
a) Heat evolved by the system is considered negative: This is true according to the sign convention explained above. When heat is released from the system, it is considered negative.
b) Heat taken up by the system is considered negative: This statement is false. According to the sign convention, heat taken up by the system is considered positive.
c) Work done by the system is considered as positive: This statement is false. According to the sign convention, work done by the system is considered positive.
d) Work done by the system is considered negative: This is true according to the sign convention explained above. When work is done on the system by the surroundings, it is considered negative.
In conclusion, the correct statements are a) Heat evolved by the system is considered negative and d) Work done by the system is considered negative. These statements align with the established sign convention for work and heat in thermodynamics.
