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 122 g and a specific heat of 1089 J/kg K. The mug starts out at room temperature (23.6 o C). Your coffee has an initial temperature of 81.7 oC and has the same specific heat as water (4186 J/kg K). 1.) What is the final temperature of coffee and mug once they come to thermal equilibrium? Tfinal= Celsius
2.) Now lets assume that instead of the 122 g of coffee, you pour in 230 g of coffee. What is the final temperature of the coffee and mug? (Again, assume that you loose no heat to the outside.) Tfinal= Celsius
3.) Now lets say that along with the 230 g of coffee, you pour in 11.7 g of cream in your mug. The cream has an initial temperature of 5.6 oC and also has the same specific heat as water. What is the final temperature of the coffee, cream and mug? (Again, assume that you loose no heat to the outside.) Tfinal= Celsius
