Ned is emptying the dishwasher. He removes a 0.20 kg glass that has an initial temperature of 30C (c = 840 J/kgC). Into it he pours 0.10 kg of diet soda (c = 4200 J/kgC) which comes out of the fridge at 5C. Assuming no external heat loss, what is the final equilibrium temperature of the glass of diet soda?

Heterogeneous mixture with larger particles that never settle is

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg·k, and 20 w/m·k.
