Answer: 8855 Joules energy is released when 115 g of changes from a liquid to a solid at its freezing point.
Explanation:
Latent heat of freezing is the amount of heat released to convert 1 mole of liquid to solid at atmospheric pressure.
Amount of heat released to freeze 1 gram of = 77 J/g
Mass of given = 115 gram
Heat released when 1 g of is freezed = 77 J
Thus Heat released when 115 g of is freezed =
Thus 8855 Joules energy is released when 115 g of changes from a liquid to a solid at its freezing point.
So,
Recall Newton's Second Law of Motion: force = mass x acceleration
Also recall:
acceleration = velocity/time
velocity = distance/time
Distance is expressed in meters.
Time is expressed in seconds.
Mass is expressed in kilograms.
v = m/s
a = m/s^2
F = m * a
F = kg * m/s^2
The unit for force is the Newton (N).
