Hey guys, having some trouble on some thermodynamics this time.
1) A glass flask whose volume is V_o at 0.0 degrees C is completely filled with mercury at this temperature. When flask and mercury are warmed to a temperature of T, a volume V of mercury overflow.
If the coefficient of volume expansion of mercury is B_merc, compute the coefficient of volume expansion of the glass.
I tried relating the two expansions with the formulas:
deltaV=B*V_o*deltaT and V=V_o(1+B*deltaT)
I tried to assume they both had the same V_o and tried subing an expression i got from the mercury expansion into my expression for glass expansion but i keep having V cancel out and its required int he final answer. Anyone know where I am going wrong or have any ideas?
