Homework Statement
Rather than retyping the problem, I've uploaded a screenshot here >> http://imgur.com/EB5MrtP
Homework Equations
[itex]Q_1 + Q_2 + Q_3 ... = 0[/itex]
[itex] mc \Delta T = Q[/itex]
The Attempt at a Solution
a. [itex] Q_{tea} + Q_{met} + Q_{cr} = 0 [/itex]
I converted the temperatures to K, so [itex]T_{cr}[/itex] and [itex]T_{met}[/itex] = 293.15K, while [itex]T_{tea}[/itex] = 373.15K
Constructing the equation, I got:
[itex] 0 = (m_{met} * c_{met}* (T_{equil}-293.15)) + (m_{cr} * c_{cr} * (T_{equil}-293.15)) + (m_{tea} * c_{tea} * (T_{equil} - 373.15)) [/itex]
I'm stuck here now, because the problem doesn't give any of the masses, it only relates them to each other. The specific heats I can find because the specific heat of water is a known value, but I'm stuck on the masses. What am I missing?
