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 pictorial representation of a circuit is called as circuit diagram.
The three important components of a circuit are : Power source, wires and load.
Load means a bulb or any other electrical equipment and power source means a battery.
<em>Out of three components, battery must be included in every circuit diagram because it provides voltage and without voltage there is no electric current.</em>
<u><em>The figure shows the symbol of a battery.</em></u>
