What is a phase change?

Hi,

Thanks for that. Is this correct:

((Va * Ta) + (Vb * Tb)) / (Va+Vb) = Tf

Va = volume in tank A whose temperature is Ta

Vb = volume in tank B whose temperature is Tb

Tf = the temperature of the water after mixing.

PS. How do i make the formula into an image like others have done?

Jeo

What is the specific heat capacity of water? Is that a constant?

Im not at school, and im not a scienctist...!

I have 2 jars of water, and just wondered if it was possible.

OK, now you have really lost me. What has thermal content and mass got to do with it? I want to mix water as a liquid form, i.e. milli-litres not grams.

And i dont know temperature change because thats what im trying to find out!!

Can someone give me a worked example?

Hi.

Is there a formula that can calculate the resultant temperature of water when two different amounts with different temperatures are mixed?

e.g.

100ml @ 20°C added to 50ml @ 60°C = 150ml @ ??? °C
