What happens when aluminium sulphate reacts with water?
When aluminum sulfate reacts with water, it forms aluminum hydroxide and sulfuric acid. This reaction is exothermic, meaning it releases heat.
What occurs when a 35-gram aluminum cube at 100C is placed in 90 grams of water at 25C in an insulated cup?
The aluminum cube will lose heat as it cools down to the final temperature of the system. This heat will be transferred to the water causing it to increase in temperature. The final equilibrium temperature will be somewhere between the initial temperatures of the aluminum and water.
Can you boil water in an aluminum foil pan?
Yes, you can boil water in an aluminum foil pan. Aluminum foil is heat-resistant and can withstand high temperatures, making it suitable for boiling water.
What happens when aluminum is mixed with nitric acid?
When aluminum is mixed with nitric acid, a chemical reaction occurs where the aluminum reacts with the nitric acid to produce aluminum nitrate, hydrogen gas, and water. The reaction is exothermic, meaning it releases heat energy. This reaction is commonly used to etch aluminum surfaces or to clean the metal.
What happens when baking soda and aluminum react together?
When baking soda and aluminum react together, they produce hydrogen gas and aluminum oxide. This reaction is exothermic, meaning it releases heat energy.

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.
Can you boil water in an aluminum foil pan?
Yes, you can boil water in an aluminum foil pan. Aluminum foil is heat-resistant and can withstand high temperatures, making it suitable for boiling water.
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 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.
What boils water faster stainless steel or aluminum pans?
aluminum conducts heat better than stainless steel.
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.
What happens when baking soda and aluminum react together?
When baking soda and aluminum react together, they produce hydrogen gas and aluminum oxide. This reaction is exothermic, meaning it releases heat energy.
What happens when you add Al to cold HCL?
the aluminum will dissolve. Generating lots of heat during the reaction
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.
