Question

Work and heat depend only on the beginning and ending states and not on the path from the beginning to mal state. : True or False. measurement. The Zeroth Law of Thermodynamics is the basis for Explain in your own words the First Law of Thermodynamics. The sign of energy transfer by Heat coming inside the system is negative positive Dimension of Work is a primary quantity, True or False An ideal gas that undergoes an isothermal process can be described by a polytropic process with an exponent (n) equal to

Answer 1

1. ANSWER- False.

Explanation- work and heat are path function. It depends upon path not process .it does not depend upon beginning and end state.

2 ANSWER- temperature.

Explanation-. According to zeroth law when two bodies are in thermal equilibrium with a third body, they are also in thermal equilibrium with each other.

3 ANSWER-first law of thermodynamics state that heat and mechanical work are mutually convertible. According to this law,a definite amount of mechanical work is needed to produce a definite amount of heat .

4 ANSWER- Positive.

Explanation- when heat coming in the system then temperature increases that is take positive sign in heat when heat remove from the system then take negative sign due to temperature decreases.

5 ANSWER-false .

Explanation- primary quantity does not depends upon any other quantity like mass,length or time etc work is depend force and distance.

6 ANSWER- polytropic index n=1

Explanation- in isothermal process temperature is constant and polytropic index is 1 .
