What is the final temperature of coffee and mug

Reference no: EM13488423

To start a great night of doing physics homework, you sit down to pour yourself a good cup of coffee. Your coffee mug has a mass 137 g and a specific heat of 1089 J/kg K. The mug starts out at room temperature (23.8 o C). Your coffee has an initial temperature of 79.8 oC and has the same specific heat as water (4186 J/kg K).

What is the final temperature of coffee and mug once they come to thermal equilibrium?

Tfinal = ____________ degrees c

Now lets assume that instead of the 137 g of coffee, you pour in 225 g of coffee. What is the final temperature of the coffee and mug? (Again, assume that you loose no heat to the outside.)

Tfinal = ____________ degrees c
