FAQ

what is the final temperature of 250g of water whose initial Temperature is 25 C if 80-g of aluminum initially at 70 C is dropped into the water? The specific heat of aluminum is 0.215 cal/C g how do you do it? our teacher did not show us how and it is not in the book

Given Data :-- Mass : Aluminium m(a) = 80 g, Water m(w) = 250 g Initial Temperature : Aluminium t? = 70 C and Water t?' = 25 C Final Temperature of both ( aluminium and water ) = T C (assume) Since Aluminium is initially at a temperature higher than that of water, it (aluminium) will lose heat to water . Heat lost by Al = Q = mass of Aluminium x sp.heat capacity of Aluminium x Temp. change = Q = 80 x 0.215 x ( 70 - T ) cal Heat gained by water = Q' = mass of water x sp.heat capacity of water x Temp. change = Q' = 250 x 1 x ( T - 25 ) According to principle of calorimetery . = Heat lost by aluminium = heat gained by water. = 250 x 1 x ( T - 25 ) = 80 x 0.215 x ( 70 - T ) = T = 27.9 C .... ( Rounded to one decimal place )...... Answer Answer .

Aluminum coils are protected against scratching and abrasion through various methods and coatings. One common method is the application of a protective film or coating on the surface of the coils. This film acts as a barrier, shielding the aluminum from external forces that could cause scratching or abrasion. Additionally, aluminum coils can undergo a process known as anodizing. Anodizing is an electrochemical method that creates a protective layer on the surface of the aluminum. This layer not only enhances the coil's resistance to scratching and abrasion but also provides it with increased durability and corrosion resistance. Another technique used to protect aluminum coils is the application of a protective lacquer or paint. This coating not only enhances the visual appearance of the coils but also acts as a barrier against potential scratches or abrasion. These protective coatings can be customized to meet specific requirements, such as UV resistance or chemical resistance. Furthermore, aluminum coils can be manufactured with a textured or patterned surface. This texturing creates a more robust surface that is less prone to scratching or abrasion. The texture helps distribute external forces more evenly, reducing the likelihood of damage. Overall, a combination of protective films, anodizing, protective coatings, and textured surfaces are employed to safeguard aluminum coils against scratching and abrasion, ensuring their longevity and performance in various applications.

The specific application and industry requirements can cause the common coil inner diameters for aluminum coils to vary. Nonetheless, 150 mm (5.9 inches), 200 mm (7.9 inches), and 300 mm (11.8 inches) are frequently utilized inner diameters for aluminum coils. These inner diameters are often selected considering factors like the coil's size, weight, ease of handling, and compatibility with manufacturing equipment. It is crucial to acknowledge that these examples are merely a few, and the actual inner diameters may differ based on the unique needs of each industry or application.

Consider the following ionization energies for aluminum:Al(g) → Al+(g) + eI1 = 580 kJ/molAl+(g) → Al2+(g) + eI2 = 1815 kJ/molAl2+(g) → Al3+(g) + eI3 = 2740 kJ/molAl3+(g) → Al4+(g) + eI4 = 11,600 kJ/mol A) Account for the trend in the values of the ionization energies.B) Explain the large increase between I3 and I4.

Iron is the main properly-known steel interior the earth. Carbon ought to have the utmost first ionization skill. it rather is considering is going to be the main resultant to resign / take one greater electron. Bromine is so on the brink of being a noble gas it is going to effortlessly income an electron to try this, for that reason it could have a low first ionization skill. the backside electronegative is interior the decrease left nook of the periodic table. It is going to the utmost as much as the better precise of the periodic table. for that reason l. a. could have the backside electronegative.

Yes, aluminum coils can be used in the production of aluminum windows. Coils are often used to create the frames and profiles of aluminum windows, as they can be easily shaped and formed into the desired configurations. This makes aluminum a popular material choice for window manufacturers due to its lightweight, durability, and corrosion-resistant properties.

Due to its inherent resistance to corrosion, aluminum coils excel in high humidity environments. Unlike metals like iron or steel, aluminum does not rust when exposed to moisture. Thus, it is an ideal option for applications where high humidity is a worry, such as air conditioning systems or refrigeration units. The corrosion resistance of aluminum primarily stems from the creation of a thin layer of aluminum oxide on its surface when it comes into contact with oxygen. This oxide layer acts as a protective barrier against further oxidation, safeguarding the metal from deterioration even in humid conditions. Furthermore, the lightweight nature of aluminum enables superior heat transfer and energy efficiency in cooling systems. This characteristic makes aluminum coils a favored choice as heat exchangers, efficiently transferring heat from the air or fluid flowing through them. Additionally, aluminum coils are commonly coated with a protective layer or treated with a corrosion-resistant coating to further enhance their performance in high humidity environments. These coatings offer an additional layer of defense against moisture and other corrosive elements, ensuring the durability and dependability of the coils. In conclusion, aluminum coils are highly suitable for high humidity environments due to their corrosion resistance and efficient heat transfer properties. The combination of these factors makes them a reliable option for various applications where moisture is a concern.

The elongation of aluminum coils refers to the degree to which the coils can be stretched or lengthened before they reach their breaking point. It is a measure of the material's ductility or ability to undergo plastic deformation without fracturing. Aluminum coils typically have a high elongation percentage, typically ranging from 10% to 30%, which means they can be stretched considerably before breaking. This property makes aluminum coils suitable for various applications where flexibility and resilience are required, such as in the manufacturing of electrical cables, automotive parts, and building materials.

The shelf life of aluminum coils can vary depending on various factors such as storage conditions, handling, and the specific alloy used. Generally, aluminum coils can have a shelf life of several years if stored properly. It is recommended to store them in a dry and clean environment, away from moisture, extreme temperatures, and corrosive substances. Additionally, handling should be done with care to prevent any damage or contamination that may reduce the shelf life. Regular inspection and maintenance are also important to ensure the integrity and longevity of aluminum coils. Ultimately, consulting the manufacturer's guidelines or contacting a professional in the industry can provide more accurate information on the specific shelf life of aluminum coils.
