Explanation:

Both because water can fall in holes and then freeze. However, water can also be chemically react with other elements and substances to wear something away.

The record time for a Tour de France cyclist to ascend the 1100-m-high Alpe d'Huez is 37.5 min. The rider and his bike had a mas
Leni [432]

Answer

given,

height of Alpe d'Huez =  1100-m

time = 37.5 min

mass of the rider and his bike = 65 Kg

the metabolic power to ride = 700 W

U = m g y

U = 65 x 9.8 x 1100

U = 700700 J

since efficiency is 25%

E_{chem} = \dfrac{U}{e}

E_{chem} = \dfrac{700700}{0.25}

E_{chem} = 2802800

E_{chem} = \dfrac{2802800}{4.19 \time 10^3}

E_{chem} =668.9\ cal

b) P = \dfrac{E_{chem}}{t}

P = \dfrac{2802800}{37.5\times 60\ s}

P = 1245.68 W

Suppose a grower sprays (2.2x10^1) kg of water at 0 °C onto a fruit tree of mass 180 kg. How much heat is released by the water
Bond [772]

There is no temperature change which drives heat flow, thus no heat will be released by the water.

<h3>Heat released by the water when it freezes</h3>

The heat released by the water when it freezes is calculated as follows;

Q = mcΔФ

where;

  • m is mass of water
  • c is specific heat capacity of water
  • ΔФ is change in temperature = Фf - Фi

Initial temperature of water, Фi = 0 °C

when water freezes, the final temperature, Фf = 0 °C

Q = 22 x 4200 x (0 - 0)

Q = 0

Since there is no temperature change which drives heat flow, thus no heat will be released by the water.
