400 cm3 of mercury at 0 degrees Celcius will expand to what volume at 50 degrees Celcius?

Question

anonymous · Answer

oh. this one..

anonymous · Answer

what is the thermal expansion constant for mercury though?

anonymous · Answer

$$\Delta V=V_0(1+\gamma\Delta T)$$
where 
delta V = change in volume in time delta T
V0 = initial volume
gamma = vometric thermal expantion constant for mercury

hey i actually figured this one out. can you help me with a different one please?

anonymous · Answer

go right ahead.

20.00 cm of total space available.  How long of a piece of brass at 20 degrees Celsius can be put there and still fit at 200 degrees Celsius?

anonymous · Answer

Brass has a linear expansion coefficient of 19X10^-6

anonymous · Answer

ok..
same formula. $\Delta L=20$
if all units are: cm, and celcius, then
$$\Delta L=L_0(1+\alpha \Delta T)\
20=L\times[1+19\times10^{-6}\times(200-20)]
$$

anonymous · Answer

I can't understand that formula. lol
