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.)

Once the mixture of root pulp is diluted, shaken, strained, then re-diluted many times to reach the desired degree of potency, the final mixture is added to lactose (a type of sugar) tablets or pellets.
dude im not gonna do your homework for you.

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.
Atmospheric pressure and saline content of the water.

The metal with the lowest thermal capacity.
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.

980000/ (6200*4.180)+18`c or 291K final answer should be 56`c or 329K.
If they're both the same substance, then the mixture will settle at 55° C. If they're different substances, then the final temp can be anything between 50° C and 60° C, depending on the substances.
As an object is heated, the rate of increase in temperature is proportional to the rate of heat added. The proportionality is called the heat capacity. Because the heat capacity is actually a function of temperature in real materials, the total amount of energy added will be equal to the integral of the heat capacity function over the interval from the initial temperature to the final temperature. If you just assume an average heat capacity over the temperature range, then the rise in temperature will be exactly proportional to the amount of heat added.
