week 13-14: thermal physics and energy in thermal process
how much heat energy must be removed from 100 g of oxygen at 24°c to liquefy it at -183°c? (the specific heat of
oxygen gas is 0.218 cal/g.°c, and its heat of vaporization is 50.9 cal/g.)
select one:
a. 14,400 cal
o
b. 19,200 cal
c. 9,600 cal

  73.11 m/s

  Explanation:

  degree = 25

  time = 16 secs

  g = 9.8 m/s^2 acceleration due to gravity.

  formula:

  F=(m)(g)tan(d)=(m)(a)

  mass will cancel for both sides so..

  (g)tan(d)=(a)

  =(9.8m/s^2)tan(25)

  =4.5698m/s^2 will be the the acceleration

  formula for Velocity is..

  V=(a)(t)

  v=(4.5698m/s^2)(16s)

  sec will cancel and will give you

  v=(4.56m/s)(16)

  V=73.11 m/s
