Were non-waxed taper wicks invented in colonial time?
A glass beaker is completely filled with 456 c.c. of a liquid when both the glass beaker and the liquid are at a temperature of 33.3oC. If the glass beaker and the liquid are cooled to 5oC. what additional volume of liquid (in c.c.) can be put into the beaker?Volumetric coefficient of expansion of liquid is 0.000109K-1 and the coefficient of linear expansion for glass is 3.2X10-6K-1
What is the beaker scale range?
the beaker can hold a different amount of liquid according to the size and mass of the beaker.
When measuring the mass of liquid in a beaker subtract the?
You must obtain and subtract the mass of the beaker.
What would be an actual property of Bromine?
It's a liquid at room temperature, it is a nonmetal.
What would you use to measure the amount of juice in a cup?
You could pour the liquid into a measuring beaker or graduated jug.You could pour the liquid into a measuring beaker or graduated jug.
Which of these properties of an unknown liquid can be found using a beaker a hot plate and a temperature probe?
You think probable to the boiling point.
Lisa had an unknown clear liquid in a beaker. After heating on a hot plate the liquid evaporated but a white solid was left inside the beaker. Based on Lisa's investigation the original clear liquid?
The liquid was a solution.
Why is it not allowed to let the bulb of the temperature touch the bottom nor sides of the beaker that contains your liquid measuring the temperature?
The bottom and sides of the beaker will be hotter than the liquid inside.
Why is it important to have the bulb of a thermometer submerged in liquid without touching the sides or bottom of the beaker?
The sides or bottom of the beaker will likely be at a significantly different temperature than the liquid.
Where should a thermometer be placed in a beaker?
Hold it by the top or use a clamp. But make sure before you take the temperature you stir the liquid around in the beaker first and that you do not let it touch the bottom of the beaker as the glass will be hotter than your liquid.
When a white powder is added to a liquid in a beaker at room temperature the beaker becomes too hot to touch What kind of reaction is this an example of?
Exothermic?
Is being liquid at room temperature a chemical property?
No, it is a (physical) state of matter, and 'liquid' is not a property
Is liquid metal a chemical property?
The fact that a metal (mercury) is a liquid at room temperature is a characteristic property of the metal, mercury. The temperature at which a metal melts to become liquid would be a chemical property of the metal.

Why is it important to stir the beaker while the water is heated?
So that the temperature of the liquid is at a constant measurement
Is the fact that mercury is liquid at room temperature a chemical property?
No. It is a physical property.
If a liquid is added to a beaker the pressure exerted by the liquid on the bottom of the beaker?
Decreases!
