To verify the equation 2.8 Concept introduction: The work is performed on an object when an object moves a certain distance s due to the force F. Mathematically, it is indicated by the dot product of the force vector F and the distance vector s. The mathematical equation is given below, W o r k = F ⋅ s = | F | | s | c o s θ Where θ is the angle between the vectors F and s . The unit of work is joules. Work is a way to transfer the energy. The energy is defined as the ability to do work and so energy and work are described using the same unit in joules.

Interpretation:

To verify the equation 2.8

Concept introduction:

The work is performed on an object when an object moves a certain distance s due to the force F. Mathematically, it is indicated by the dot product of the force vector F and the distance vector s. The mathematical equation is given below,

Work = F⋅s = |F||s| cosθ

Where θ is the angle between the vectors F and s. The unit of work is joules. Work is a way to transfer the energy. The energy is defined as the ability to do work and so energy and work are described using the same unit in joules.

Water appears in nature in all three common states of matter. Water is a tasteless, odorless liquid at standard temperature and pressure. 2. The addition of salt in the distilling mixture made the water impure and saline. The addition of 5 drops of the silver nitrate solution into the distillate determines whether the distillate is impure or pure water. 3. The ideal electrical conductivity of totally pure water is 0.055 microSiemens, whereas typical deionized water has an electrical conductivity of 0.1 microSiemens. The freezing point of water at 1 atm is 100degC. 4. From the air, oxygen can slowly diffuse across the water’s surface from the surrounding atmosphere, or be mixed in quickly through aeration, whether natural or man-made. The aeration of water can be caused by wind (creating waves),…

1. Cows on a farm sometimes end up eating little pieces of metal, like tacks or little scraps of barbed wire. These bits of metal end up stuck in the cow's stomachs, so they have to be removed by feeding the cow a magnetic pill called a "cow magnet." As it passes through the cow's digestive tract, the magnet picks up the little pieces of metal, and the cow ultimately passes it out, The AS for this process is POSITIVE / NEGATIVE / ZERO. The AH for this process is POSITIVE/NEGATIVE / ZERO. The AG for this process is POSITIVE / NEGATIVE / ZERO. When pieces of metal get stuck to the magnet, they INCREASE / DECREASE / DO NOT AFFECT its temperature.
