You pour 150.0 g of hot coffee at 95.0 degrees Celcius into a 210.0- g glass cup at 28.0 degrees Celcius. If they come to thermal equilibrium quickly, what is the final temperature (in degrees Celcius)? Assume no heat is lost to the surroundings.

Step 1

Heat lost by the hot coffee must be the heat gained by the glass.

Heat energy transfer from coffee to glass can be expressed as,

Step 2

The specific heat capacity of coffee can be approximated to that of specific heat capacity of water.

Substituting the values,

Step 3

Rewrite the expression for T...
