Answer:
pressure of the gas inside the lungs will be =1.35 atm
Explanation:
so for calculation of pressure of gas we will use the formula
(remember to convert *C to kelvin)
PV₁/T₁ = P₂V₂/T₂ As we know that Temperature = 310.5 k =37 degree
so for pressure P₂
P₂=P₁V₁T₂/T₁V₂
= ((1.00atm)(2.20L)(310.15K))/ ((298.15K) (1.70L)
=1.35 atm
(remember to convert *C to kelvin)
The answer is D.) respitory tract
If the width is increased it would be harder to stretch more force will be needed to stretch it
The sugar pill serves as a control.
The control in experiments is a sample that remains the same throughout the experiment and it is used to compare the results of the main experiment to. It serves to guarantee that changes noted in the experiment are from the variables introduced and not something else.
Answer:
B. Because weather is a complex interaction among many different variables that are constantly changing
