Famers spray water to the crops if they know that the
temperature will fall below zero. They spray water so that the
fruits on trees will not freeze and become inedible. Use your
knowledge in latent heat to explain why this will help prevent the
fruits from freezing.
Application
A player kicks a ball (m=45.9 grams) from a height of 8
m above the ground at a speed of 20 m/s. At the maximum height
above the ground, the ball is moving at 12 m/s. If air resistance
is negligible, what is the maximum height reach by the football and
at what velocity will it strike the ground.
As a part of an experiment, a student cools a 3kg metal
object to a temperature of -30oC. He places the metal in 5L of pure
water initially at a temperature of 50oC. The final temperature of
the mixture is 25oC. What is the specific heat of the
metal?
A 1.50 × 102 𝑔 piece of brass (specific heat capacity
3.80 × 102 𝐽 /𝑘𝑔𝑜𝐶 ) is submerged in 400.0 mL of water at 27.7 °C.
What is the original temperature of the brass if the mixture has a
temperature of 28.0 °C?
