Answer:
e. All of these statements are false.
Explanation:
As we know that heat transfer take place from high temperature to low temperature.
It is possible to convert all work into heat but it is not possible to convert all heat in to work some heat will be reject to the surrounding.
The first law of thermodynamics is the energy conservation law.
Second law of thermodynamics states that it is impossible to construct a device which convert all energy into work without rejecting the heat to the surrounding.
By using heat pump ,heat can transfer from cooler body to the hotter body.
Therefore all the answer is False.
Explanation:
A compound is a pure substance composed of two or more different atoms chemically bonded to one another. A compound can be destroyed by chemical means. It might be broken down into simpler compounds, into its elements or a combination of the two.
Less because now there is less force on the scale and you are unbalanced. Therefore the scale will have a lower number then before.
Since D=M/V, the answer would be 2.7
1) Plates movement happens very slowly.
2) The earth's lithosphere is divided into pieces
3) they are caused by convection currents in the asthenosphere (upper mantle)
