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

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
