The figure shows a pV diagram for an ideal gas in which its pressure tripled from a to b when 651 J of heat was put into the gas.
How much work was done on or by the gas between a and b?
Without doing any calculations, decide whether the temperature of this gas increased, decreased, or remained the same between a and b.
By how much did the internal energy of the gas change between a and b?
Did it increase or decrease?
What is the temperature of the gas at point b in terms of its temperature at a , Ta.
