A 10 L sample of helium is measured to be 90°C. If the temperature changes to 65°C, what is the volume? Assume constant pressure of the system. (7 points) A. 22.4 L B. 44.8 L C. 9.2L D. 8.2L E. 7.2L

Explanation / Answer

1)

a)

Boyle’s law gives the relation between P and V

the relation is P*V = constant

this is inverse relation

4th graph depicts it

Answer: rightmost graph

b)

Boyle’s law
