Mix Liquids of Different Temperatures

Calculate the temperature of a mix of liquids with different temperatures. For water and other liquids. If two different liquids shall be mixed, for each the heat capacity must be given (water has about 4.2 Kj/(kg*K)). The two liquids must not chemically react with each other. As amount, the weight is needed.
Please enter two amounts and two temperatures, or all three temperatures and click Calculate.

Example: if you pour one kilogram of a liquid that has a temperature of 60 degrees Celsius together with two kilograms of another liquid that has a temperature of 30 degrees Celsius and they do not react chemically with each other, then you will naturally have three kilograms of a liquid that has a temperature of 40 degrees, assuming that both starting liquids are also liquid at this temperature.

The two liquids do not mix homogeneously straight away. The calculated temperature of the mixture is therefore the average value; the mixture has different temperatures at different points at the beginning. By stirring, you can create a more homogeneous mixture, but this adds more energy to the system, which is converted into heat, among other things, so you should not stir too quickly. Finally, there are liquids that are very difficult to mix or not at all, such as water and oil. The oil will float to the top, at least with most oils. In this case, it will of course take a long time for the temperature to be evenly distributed and will adjust to the ambient temperature again during this time.
In any case, the temperature is always only a snapshot that is subject to constant changes.
