80 J of work are done on the gas in the process shown in Figure EX19.3. What is V1 in cm3 ?
The value of is
The work done has represented as energy that is transferred between system and environment.
As it is isothermal process , work done is positive.
The area of the triangle is
The area of rectangular is
So the total work done is
Here work done energy is 80J
So the value of is
The burner on an electric stove has a power output of 2.0 kW. A 750 g stainless steel teakettle is filled with 20°C water and placed on the already hot burner. If it takes 3.0 min for the water to reach a boil, what volume of water, in cm3, was in the kettle? Stainless steel is mostly iron, so you can assume its specific heat is that of iron.
