A steel bottle contains nitrogen gas at STP. What is the final pressure if the temperature is changed to 155°C?

Option D

Explanation:

As we know at

PV = nRT

at STP,

Pressure is  1 atm and temperature is 273 K

Hence, option D is correct

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

that's what i got you can count the number of atoms
