Answer:
            1.126 L

Solution:

Let's assume the gas is behaving ideally, then initial and final states of given gas are given as,

                                      P₁ V₁ / T₁  =  P₂ V₂ / T₂   ---- (1)
Data Given;

                  P₁  =  0.572 atm

                  V₁  =  2.15 L

                  T₁  =  25 °C + 273  =  298 K

                  P₁  =  1.00 atm

                  V₂  =  ?

                  T₂  =  0 °C + 273  =  273 K

Solving equation 1 for V₂,

                 V₂  =  P₁ V₁ T₂ / T₁ P₂

Putting Values,

                 V₂  =  (0.572 atm × 2.15 L × 273 K) ÷ (298 K × 1 atm)

                 V₂  =  1.126 L

A doorknob makes it easier for you to open doors because it is what type of simple machine?
vagabundo [1.1K]

Answer: Wheel and Axle

Both of these work together to form a simple machine. You can't have one without the other.

If you try to turn just the axle itself, then you'll find it takes a lot of work. This is because the inertia of the axle wants to keep the object at rest. Also, you won't have a lot of torque due to the small radius compared to what a doorknob can offer.

Using a doorknob is like putting a (steering) wheel on an axle. This increases the radius and therefore increases the torque. You put in less work into the system and get more out of it.
