introduction to thermal sciences solutions

. Litmus, a purple dye extracted from the lichen plant, is commonly used as an indicator in laboratories. Acids change the colour of litmus solution to red, and bases change the colour of litmus solution to blue. Turmeric is another common household indicator. A stain of turmeri..

Thermal Power Plant (Thermal Energy) - Large amount of fossil fuels are burnt everyday in power stations to heat up water, to produce steam which further runs the turbines to generate electricity. The transmission of electricity is more efficient than transporting coal or petrol..

The water at the surface of an ocean gets heated by the heat of the sun and attains a higher temperature than the colder water at deeper levels in the ocean. So, there is always a temperature difference between the water "at the surface of ocean" and "at deeper levels." At many places in the ocean..

Every organism whether plant or animal is unique in itself. There is a wide diversity in the flora (plants) and fauna (animals) in the world. The diversity we see today is the result of 3.5 billion years of organic evolution. During the course of this evolution several species vanished from the sur..

We have learnt about the motion of objects based on the definition of displacement, velocity and acceleration. Now let us see the causes that influence the motion of bodies. Have you wondered why certain natural phenomena occur and why they continue to occur in the same way? For instance - why do t..

The cells that make up our body are so small that you could fit over 200 of them on the full stop at the end of this sentence Before we plunge into the chapter, here are some interesting facts about cells. Read on... The word cell is derived from the Latin word cellula which means a little ..

We have learnt that a force changes or tends to change the state of rest, speed or direction of motion of an object, i.e., force produces an acceleration. In this chapter, we are going to identify one of the forces which produces acceleration in all objects on the surface of the Earth irrespective ..
