If the specific heat of aluminum is 899 Jkg and degC and the specific heat of water is 4190 Jkg and degC which of the following statements is true?
The specific heat of water (4190 J/kg·°C) is significantly higher than that of aluminum (899 J/kg·°C). This means that water can absorb more heat energy per kilogram for each degree Celsius of temperature change compared to aluminum. As a result, water heats up and cools down more slowly than aluminum, making it more effective for temperature regulation in various applications.

Which would have higher temperature change water or aluminum?
Starting from the same temperature and for the same amount of heat input, aluminum would wind up with a higher temperature than water because water has a higher heat capacity (it takes more energy to raise its temperature) than aluminum.
A 48.26g sample of aluminum at 100.0C is dropped into 34.47g of water at 25.0C What is the final temperature?
To find the final temperature, you can use the principle of conservation of energy, Q lost = Q gained. The heat lost by the aluminum will be equal to the heat gained by the water. Use this formula: (mass of aluminum) x (specific heat capacity of aluminum) x (change in temperature) = (mass of water) x (specific heat capacity of water) x (change in temperature). You can then solve for the final temperature.
What is the specific gravity of aluminium in kg?
the atomic mass is 26.981539 if that's what you're looking for. NO. Not at all. The question wasn't atomic weight, but SPECIFIC WEIGHT. SPECIFIC WEIGHT is the ratio of DENSITY of the material to the Density of Water at an established set of conditions. Thus, the Specific weight of Aluminum is approximately 2.7 times the weight of water. So that if you have a cubic foot of aluminum, it will weight more or less two point seven times the weight of a cubic foot of water, that is around 168.5 pounds, but bear in mind that different commercial aluminum alloys can vary from 2.5 to 2.9 in their specific weight, but 2.7 is a good value for practical purposes.
Why it aluminum bitter?
Aluminum itself is not inherently bitter; however, some aluminum compounds can have a bitter taste. This bitterness is often due to the presence of impurities or the specific chemical interactions that occur in certain aluminum salts, like aluminum sulfate. Additionally, the perception of bitterness can vary based on individual taste sensitivity and the context in which aluminum is encountered, such as in food or water treatment processes.
Which component (the aluminum or water experienced a greater change in temperature?
To determine which component experienced a greater change in temperature, you would need to compare the initial and final temperatures of both the aluminum and the water. Generally, aluminum has a lower specific heat capacity than water, meaning it can experience a greater temperature change with the same amount of heat transfer. Therefore, if both components were subjected to the same heat transfer, the aluminum would typically exhibit a greater change in temperature than the water.
What heats up faster water or aluminum?
Aluminum heats up faster than water because it has a lower specific heat capacity. This means that it requires less energy to raise the temperature of aluminum compared to water.

Starting from the same temperature and for the same amount of heat input, aluminum would wind up with a higher temperature than water because water has a higher heat capacity (it takes more energy to raise its temperature) than aluminum.

What is the specific gravity of aluminum in pounds?
Specific gravity is not measured in pounds. It is a dimensionless quantity, which results by dividing (in this case) the density of aliminium, by the density of a reference substance, usually water. The result of the division will be the same, whether you use international units (SI, i.e. metric), or obsolete units.
Is aluminum sulfide soluble in water?
Aluminum sulfide is insoluble in water, as it does not dissociate or dissolve when mixed with water.
Which of the following statements about water is false. Liquid water has a low specific heat which makes it a poor coolant 2 Solid water ice is less dense than liquid water or what?
The false statement is that liquid water has a low specific heat, which makes it a poor coolant. In fact, liquid water has a high specific heat capacity, which means it can absorb and release a large amount of heat with only a small change in its own temperature. This property makes water an effective coolant in various applications.
Which would take more energy to increase temperature by 5 degrees water or Aluminum?
It would take more energy to increase the temperature of water by 5 degrees than aluminum. This is because water has a higher specific heat capacity, meaning it requires more energy to raise its temperature compared to aluminum.
Aluminum has a density of 171 lb ft3 What would be its specific gravity?
The specific gravity of a substance is the ratio of its density to that of water. Since water has a density of 62.4 lb/ft3, the specific gravity of aluminum can be calculated as 171 lb/ft3 / 62.4 lb/ft3 ≈ 2.74.
If the specific heat of aluminum is 0.902 and the specific heat of copper is 0.268 what makes copper a better choice to use for hot water lines in your house?
This means that copper will not absorb the heat from the water as much as the aluminum. Aluminum will "steal" more heat from the water- which you do not want. You need the heat to stay with the water until it serves its purpose.
Which of the following would be the best material to use for making tea kettles A copper specific heat 380 B iron specific heat 450 C graphite specific heat 710 D aluminum specific heat 920?
D. Aluminum would be the best material to use for making tea kettles because it has a higher specific heat capacity compared to the other materials listed. This means that it can absorb and retain heat more effectively, allowing water to boil faster and more efficiently.

Does aluminum dissolve in water?
Under normal circumstances, aluminum does not react with water.
