Asample of hydrogen gas has an initial pressure of 2.86 atm and an initial volume of 8472 ml if the volume of the
were decreased to 365.8 ml, what would the new pressure be? gas law used:

Gas law : Boyle's law

New pressure: 66.24 atm

Concept tested: Gas laws (Boyle's law)

We are given,

We need to determine the new pressure, P₂

P₂ = P₁V₁ ÷ V₂

   = (2.86 atm × 8472 mL) ÷ 365.8 mL

   = 66.24 atm

Therefore, the new pressure is 66.24 atm

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:
