Question

calculate and give the right answer: 1lt of water at 30°c is added to 1lt of waterat 50°c.​

Answer 1

Answer:

the temperature will slightly less than 40°C. Explanation: Because water expands when heated, 1 litre of water at 50°C will have less mass than 1 litre of water at 30°C. As a result, the 30°C litre has slightly more than the 50°C litre, and thus the average will end up slightly less than 40°C.

Answer 2

Answer:

The temperature of the water is somewhere between 30 degrees Celsius and 50 degrees Celsius. (There is no way to calculate this. We must just take an educated guess)
