Hi people, I am just having a little play with some physics because basically I went to drink my tea this morning and its always too hot. Then I wait and its always too cold. So therefore I fancy to try and workout how long should I leave it until it is cool. I found a study that says 60 deg c is 'perfect'. Therefore for my size of mug I want to know how long I should leave it in the morning.
My tea' consists of the ceramic mug, water, and milk. Obviously the tea bag will absorb some heat but I can't be bothered with that.
I assume that heat will be lost through conduction with the air at the sides of mug, convection from the top and also radiation (can I assume black body?).
What would be a good way of going about this? I assume Newtons law of cooling is the way forward but I haven't done it for a long time.I fancy going reasonably accurately with this so just need to check my line of thinking

No attempt, I don't wish to have an answer just some ideas that I can look into so I can go away and work some stuff out. [/B]
