Amass of a gas has a volume of 4m’3 a temperature of 290 k an obsolete pressure of 475 kpa. when the gas is allowed to expand to 6.5 m’3, it’s new temperature is 277 k. what is the absolute pressure of the gas after expansion? thnk you

What is the things about?

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current
