THE ANSWER IS 62.8 DEGREES.....
if 2.5kg of hot water at 100c is added to 10kg of cold water at 28c and stirred well. what is the final temperature of mixture? (neglect the heat absorbed by container and the heat lost by the surroundings.)
THE ANSWER IS 62.8 DEGREES.....
The final temperature of the mixture will be between 5 and 20 degrees Celsius, closer to 5 degrees since a larger mass of water is at that temperature. To find the exact final temperature, you can use the principle of conservation of energy (Q lost = Q gained).

To determine the temperature change when 40g of ice is added to 100g of water at room temperature, you must consider the heat transfer involved in melting the ice and warming the resulting water. The heat absorbed by the ice to melt (latent heat of fusion) and then raise its temperature to the final equilibrium temperature will lead to a decrease in the temperature of the warm water. The final temperature will depend on the initial temperature of the water and the specific heat capacity of both water and ice, which typically results in a lower equilibrium temperature than the initial temperature of the water.

I'll assume here that by "70 temperature" you mean "70 degrees Celsius". Basically, you have to calculate the average temperature of all of the water in the mixture, which will be the final temperature once it's well stirred. The 200 grams of water at 10 degrees represent 2/3 of the total amount of water (300 grams), so thus, multiply 10 by 2/3 to determine their contribution to the final temperature. You will get 20/3. The 100 grams of water at 70 degrees represent 1/3 of the total amount of water, so multiply 70 by 1/3 to determine their contribution to the final temperature. You will get 70/3. When you add together the two temperatures you get 90/3, which is equal to 30. Therefore, the final temperature is 30 degrees Celsius.
The final temperature of a mixture of hot and cold water depends on the initial temperatures of the two water sources and the amounts of hot and cold water being mixed together.

To find the final temperature of the mixture, we can use the principle of conservation of energy, assuming no heat is lost to the surroundings. The heat gained by the cooler water (50 mL at 20°C) will equal the heat lost by the warmer water (200 mL at 70°C). The final temperature will be closer to the initial temperature of the warmer water due to its larger volume, likely resulting in a final temperature around 64-66°C.
To find the final temperature, you can use the equation: q = mcΔT, where q is the heat added, m is the mass, c is the specific heat capacity of aluminum, and ΔT is the change in temperature. Rearrange the equation to solve for final temperature, T. Substitute the values and solve for T.

Well, honey, you stir mixtures before using them to ensure that all the ingredients are evenly distributed. Nobody wants to bite into a clump of salt or a pocket of flour, right? So give that mixture a good stir and save yourself from any unpleasant surprises when you're cooking or baking.
The formula for finding the final temperature in specific heat calculations is given by: [ T_f = T_i + \frac{Q}{m \cdot c} ] where (T_f) is the final temperature, (T_i) is the initial temperature, (Q) is the heat added or removed, (m) is the mass of the substance, and (c) is the specific heat capacity. This equation assumes no phase change occurs during the process.
When hot metal is added into the water then the metal looses its energy into the water and this heat is gained by the water, so the temperature gets increases when hot metal added into it i.e final temperature is greater than initial temperature of water.
