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
d. 2.400 cal
. 4,800 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
