Question

what is the equilibrium temperature when pouring 200 grams at 80 degrees Celsius while at room temperature into a 50 gram brass flask?

science physics

Answer 1

Answer #1

specific heat of brass is 380 J/Kg-K

specific heat of water is 4186J/Kg-K

Room temperature is 20^oC

Heat gained by brass flask = Heat lost by water

M_BC_B(T-T_B)=M_wC_w(T_w-T)

0.05*380*(T-20)=0.2*4186*(80-T)

856.2T=67356

T=78.67^oC

A glass flask has a volume of 500 ml at a temperature of 20 degrees celsius. The flask contains 492 ml of mercury at an equilibrium temperature of 20 degrees celsius. The temperature is raised until the mercury reaches the 500 ml reference mark. The coefficients of volume expansion of mercury and glass are 18*10^-5 K^-1 and 2.0*10^-5 K^-1, respectively. The temperature at which this occurs, in degrees celsius is closest to:
