Here we will see the work formula in thermodynamics and also we will knowhow to calculate work done by the compression or expansion of a gas. As we already studied, work is some sort of energy required to move an object in the direction of the force. The work in gases can be done by...
Alternatively, work can also be calculated using the change in energy of a system, as in the formula W = ∆E. What is the difference between positive and negative work in thermodynamics?In thermodynamics, positive work is done on a system when energy is transferred from an external source ...
, which is defined as the work done by a force of 1 newton in moving an object through a distance of 1 meter in the direction of the force. a weightlifter lifts a barbell weighing 25 kg and displaces it from the ground by 2 m. here, the work done upon the barbell is against ...

Work, power, and energy play a significant role in solving various JEE Main problems, particularly in mechanics and thermodynamics. Some common applications include: Calculating the work done by a force Determining the power of a machine or engine Analyzing the energy transformations in different proc...
Suppose 100 Joules of work is done on a system and that 300 Joules of heat are delivered to the system. Which of these is predicted by the first law thermodynamics? (a) The internal energy U of the system does not change. (b) The internal energy U of the ...
An example where much work is done on stretching the adhesive is a pressure-sensitive adhesive that forms filaments before the adhesive detaches. If the phases are separated in dry air, work of adhesion WA is given by Eq. (2.9). (2.9)WA=γA+γS−γAS But if separation is in the ...
The author states that the thermodynamics is tricky because its general formula derived from Maxwell's equations that involves integral overall space. The author mentions that the second law is important to appreciate that net work must be done to pump heat uphill and achieve cooling.Moya...
If a piece of work is done in x number of days, then the work done in one day = 1/x Total Wok Done = Number of Days × Efficiency Efficiency and Time are inversely proportional to each other X:y is the ratio of the number of men which are required to complete a piece of work,...
