Question

A syringe containing 2.56 mL of He gas at 75.2 degrees Celsius is cooled to 18.2 degrees Celsius. What is the final volume of the gas?

Answer 1

v = 2.141 ml

Step-by-step explanation:

we can use the "ideal gas law" :-

PV=nRT

p :- pressure ( pa )

V :- Volume ( m³ )

n :- amount of substance ( mol )

R :- Ideal gas constant ( 8.314 Jmol-¹ K-¹ )

T :- Temperature ( K)
