Athermometer containing 8.3g of mercury has broken. if mercury ha a density of 13.6g/ml. what volume is spilled?

The volume of mercury spilled is 0.61 ml.

Explanation:

Density is defined as the mass contained per unit volume.

Given : Mass of mercury= 8.3 grams

Density of mercury=

Putting in the values we get:

Thus the volume of mercury spilled is 0.61 ml.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
