why is the air at higher altitudes cooler than that at lower altitudes
Explain why thunderstorms are more likely in the summer than in the fall during rainstorms, after calculating the energy released under each condition. Assume a summer temperature of 90°F and fall 40°F and that the rain is 40°F. Note that the specific heat of water is 4.184 J/g-˚C, and that the heat of vaporization of water is 2600 J/g.
Why are copper straps (rather than iron straps or bent over nails) used to hold household copper wire lines in place? when an iton post is immersed in water, rust forms at the water line and the iron post pits below the water line. Explain why this happpens. Why do aluminum pots and pans develop a pitted surface when taboe salt is added to the cooking water?
What is the operation principle of an evaporative cooler and what are the limitations of an evaportive cooler (4%)? Why people always sweat in summer but not in winter even winter has higher relative humidity. Using the Psychometric Chart below to support your answer (8%) $

It is a well-known fact that water has a higher specific heat capacity than iron. Now, consider equal masses of water and iron that are initially in thermal equilibrium. The same amount of heat, 30. calories, is added to each. Which statement is true? They are no longer in thermal equilibrium; the iron is warmer. They remain in thermal equilibrium. They are no longer in thermal equilibrium; the water is warmer. It is impossible to say without knowing the exact...
Question 1: Your bear cooler is made of 20-mm-thick polystyrene (k = 0.021 W/m.K) and has interior dimensions of 0.5 mx0.3 m X 0.3 m. If you fill the inside with an ice-water mixture (so the temperature is maintained at 4°C) and leave the cooler on the porch on hot summer day (ambient temperature of 30°C ), what is the heat flux through the container wall? Assume negligible heat gain through the base of the cooler. You may have to...
5. Because of the high specific heat capacity of water compared to that of soil, a large lake takes longer to heat in the summer than an equivalent area of land. This effect moderates the temperature along the lakeside. But how does the cooler lake keep lakeside communities cooler, i.e. what is the mechanism of energy transfer? (0.5 mark)
4. When an iron post is immersed in water, rust forms at the water line and the iron post pits below the water line. Explain why this happens. (52 Why do aluminum pots and pans develop a pitted surface when table salt is added to the cooking water? e faco of conner which is exposed
1. Why is solid water less dense than liquid water? 2. Why is water called the universal solvent?
