Question

If I liter of water at 40 Degree Celsius is mixed with water at 80 Degree Celsius what will be the temperature of the water solution?

Answer 1

Answer:

It will be slightly lower than—or possibly much lower than—40 degrees..

Explanation:

You have to average the temperatures, but the average is weighted by mass, rather than by volume. Because water expands when heated, one liter of water at 50 degrees will have less mass than one liter of water at 30 degrees. As a result, the 30 degree liter has slightly more mass than the 50 degree liter, and thus the average will end up slightly less than 40 degrees. In addition, the heat capacity of water also changes with temperature, in a manner that is not closely related to the change in the density of water with temperature.

Since I don’t know which temperature scale you’re using, I can’t give you a more exact answer. Indeed, if these temperatures are in Fahrenheit, and the 30 degree sample is frozen, a significant part of the thermal energy of the warmer sample will go to melting the frozen sample, instead of raising its temperature, and that means that the resulting temperature will actually be significantly below 40 degrees.

i hope it will help you

Answer 2

Answer:

Hey

The temperature of the water would be lower then before

hope this helps

pls mark my answer as brainliest plzzzzzzz

thank you
