If a 430 mL ordinary glass beaker is filled to the brim with ethyl alcohol at a temperature of 6.00°C, how much (in mL) will overflow when their temperature reaches 22.0°C?

Answer : The volume of ethyl alcohol overflow will be, 7.49 mL

Explanation :

To calculate the volume of ethyl alcohol overflow we are using formula:

where,

= volume expand = ?

= volumetric expansion coefficient =

= initial volume = 430 mL

= final temperature =

= initial temperature =

Now put all the given values in the above formula, we get:

Thus, the volume of ethyl alcohol overflow will be, 7.49 mL

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
