No because it will contain the same amount of mass, just in different forms.
        
                    
             
        
        
        
Answer:
We can retain the original diffraction pattern if we change the slit width to d) 2d.
Explanation:
The diffraction pattern of a single slit has a bright central maximum and dimmer maxima on either side. We will retain the original diffraction pattern on a screen if the relative spacing of the minimum or maximum of intensity remains the same when changing the wavelength and the slit width simultaneously.
Using the following parameters: <em>y</em> for the distance from the center of the bright maximum to a place of minimum intensity, <em>m</em> for the order of the minimum, <em>λ </em>for the wavelength, <em>D </em>for the distance from the slit to the screen where we see the pattern and <em>d </em>for the slit width. The distance from the center to a minimum of intensity can be calculated with:
                                                     
From the above expression we see that if we replace the blue light of wavelength λ by red light of wavelength 2λ in order to retain the original diffraction pattern we need to change the slit width to 2d:

Answer:
Yes, the heat that flows into the system is used to change the internal energy of the gas and becomes work done by the piston. 
Explanation:
First law of thermodynamics known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another.
The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics.
This is the first law of thermodynamics 
ΔE= Q− W 
ΔE= change internal energy of the system.
Q= heat transfer into the system 
And 
W= work done by the system.
Rewriting the equation 
ΔE= Q− W 
Q=ΔE +W 
Show that the heat flowing l into the system is transferred to the internal energy of the system and the work done by the piston 
So the third option is correct
 
        
             
        
        
        
Answer:
The rate at which work is done would be power. Bonus: The SI unit of work is Joules.

Its D i think because it doesnt refer to any other things
