The United States has high speed trains running between Boston and New York capable of speeds of up to 160 m/hr. Are these trains faster or slower
than the fastest trains in the United Kingdom, which reach speeds of 225
km/hr? Explain your answer.

257 kilometers/h

Explanation:

First , convert the speed from m/hr to km/h

160m/h= 257 km/h

Hence, The trains in the U.S.A (257 km/h) are faster than the trains in the U.K(225 km/hr)

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
