Hi I need help with these and I don't really understand this topic.

3. The figure shows a pV—diagram for an ideal gas in which its absolute temperature at b is one- fourth of its absolute temperature at a. (a) What volume does this gas occupy at point b? (b) How much work was done in this process? Was it done by or on
the gas? (1:) Did the internal energy of the gas increase or decrease from a to b?
How do you know? (d) Did heat enter or leave the gas from a to b? How do you know? 4. The process abc shown in the pV—diagram in the figure involves
0.0175 mole of an ideal gas. (a) What was the lowest temperature the gas reached in this process?
Where did it occur? (b) How much work was done by or on the gas from a to b?
From b to c? (c) If 215 J of heat was put into the gas during abc, how many of those
joules went into internal energy? platm}
0 2.0 4.0 5.0 5. A sample of monatomic ideal gas is taken from a to b on the pV—diagram shown in the figure. During this process, heat is added and the pressure doubles.
(a) How much work is done by or on the gas? Explain. (b) How does the temperature of the gas at or compare to
its temperature at b? Be specific. (1:) How much heat is added to or removed from the gas? (d) How does the internal energy of the gas at (I compare to the
internal energy at b? Again, be specific and explain.
