**1. A mercury thermometer has a bulb of volume .100 cm^3 at 10degreesC. The capillary tube (initially empty) above the bulb has a cross-sectional area of .00012 cm^2. How much will the mercury rise when the temperature rises by 30degreesC? Ignore the thermal expansion of the glass bulb and tube. (beta of mercury = 1.8 x 10^-4 degreeC^-1)**

## Homework Equations

Q = mcdT

H = kAdT/L

## The Attempt at a Solution

I tried plugging in numbers for H = kAdT/L and I'm not sure what the "beta of mercury" is. I'm pretty bad at thermo.
