59. To help prevent frost damage, fruit growers sometimes protect theircrop by spraying it with water when overnight temperatures are expectedto go below freezing. When the water turns to ice during the night, heatis released into the plants, thereby giving a measure of protection againstthe cold. Suppose a grower sprays 7.2 kg of water at 0 °C onto a fruit tree.(a) How much heat is released by the water when it freezes? (b) Howmuch would the temperature of a 180-kg tree rise if it absorbed the heatreleased in part (a)? Assume that the specific heat capacity of the tree is

Part A) Calculate heat lost by water when it freezes to zero degrees Celcius.

Early mountaineers boiled water to estimate their altitude. If they reach the top and find that water boils at 84°C, approximately how high is the mountain?
A tremendous force is generated when waterfreezes into ice and expands in volume by 9.0%. Suppose a 1.000-m3cube of liquid water freezes into ice that is 1.000 m on a side by1.090 m tall. How many 68-kg students would the ice be able tolift? Determine this by calculating the amount of force on the top1.000-m2face that would be required to squeeze 1.090 m3of iceback to 1.000 m3, assuming all of the volume change occurs alongthe vertical direction
In the United States, energy for household heating is generally sold using English units, e.g., therm, gal, and cord. A house in Wisconsin uses 1200 therms of thermal energy during the heating season. Calculate the cost of fuel if the furnace uses (a) natural gas with an efficiency of 70%; (b) No. 2 fuel oil, efficiency 65%; (c) kerosene, efficiency 99.9% (unvented); and (d) wood with l5% moisture with an efficiency of 50%. Use the data in Tables 2.2, 2.7, and 2.13. The efficiencies are based on the HHV. Assume the cost of natural gas is $8/MBtu, the cost of No. 2 fuel oil is $3/gal, the cost of kerosene is $3.50/gal, and the cost of wood is $100/cord. Assume the bulk density of cord wood is 30 lbm/ft3 .
As2...Suppose that we could increase the atmospheric pressure on the surface of Mars to 0.2 bar, by vaporizing the polar caps and subsurface ice. This atmosphere would then likely decrease over time, as a result of several processes, such as escape into space, and erosion by the solar wind. How would the surface pressure decrease as a function of time? How much time would it take until the pressure is only 0.1 bar?
A balloon filled with helium (of density ρHe = 0.164 kg/m3 ) has a cube shape and rises through the stratosphere. Air density is given by ρ(z) = ρa exp(− gz/ RT), where ρa = 1.225 kg/m3 is the density of air at the sea level, g = 9.81 m/s^2 is the gravitational acceleration, R = 287.06 J/kg/K is the specific gas constant of air, and T is the air temperature, which is constant in the stratosphere and equal to 217 K (Note that this expression for the atmospheric density is strictly correct only in the isothermal region of the stratosphere. However, please use it for solution to this problem). This balloon is designed so that ρHe and its side length h = 30 cm remain constant for all z. The lower surface is located at z and the upper surface at z + h. Derive an expression for the buoyancy force on the balloon and compute the maximum altitude to which the balloon rises in a unit of m.

A cold wave in the US brings temperature to -53 °C. A cold air mass, known as the polar vortex, passed through the United States in January 2019 and caused the temperature to reach -53 °C. Several states declared an emergency, while Chicago and North Dakota experienced -30"C and -37"C, respectively. It can be said that the lowest temperature recorded, in Kelvin, by the Chicago thermometers was:
