Why do beaker need to cool before weighing?
A hot beaker warms the air around it, which causes it to rise. For very sensitive balances, the updraft produced can reduce the measured weight.
How do you calculate mass of water in the beaker by difference?
To calculate the mass of water in a beaker by difference, first weigh the empty beaker and record its mass. Next, fill the beaker with water and weigh it again to obtain the combined mass of the beaker and water. Subtract the mass of the empty beaker from the total mass to find the mass of the water alone. This method allows for an accurate measurement by accounting for the container's weight.
What is the thing you put a hot beaker on?
You typically place a hot beaker on a heat-resistant surface, such as a lab mat or a hot plate. Additionally, a ceramic or metal beaker stand can be used to safely hold the beaker while allowing for airflow to dissipate heat. Always ensure that the surface can withstand high temperatures to prevent damage or hazards.
Why did the students need to weigh the glass beaker before they could calculate the weight of the water inside it?
The students needed to weigh the glass beaker first to determine its mass, which is essential for calculating the total weight of the water when combined with the beaker. By knowing the beaker's weight, they could subtract it from the total weight after adding water, allowing them to accurately measure just the weight of the water itself. This method ensures precise calculations and helps avoid errors in determining the water's mass.
Would condensation form on the outside of a beaker full of hot water why or why not?
Yes, condensation could form on the outside of a beaker full of hot water if the surrounding air is cool enough to cause the water vapor in the air to condense on the cooler surface of the beaker. This is similar to how condensation forms on a cold glass of water on a warm day.

A hot beaker warms the air around it, which causes it to rise. For very sensitive balances, the updraft produced can reduce the measured weight.
What is a beaker tong?
A beaker Tong is a tool to hold you beaker. You use them when the beaker is too hot to touch. You use it to transport it, often used with Bunson burners. They are best used to hold a hot Beaker.
If you were holding a beaker in which an exothermic reaction just took place would the beaker feel hot or cold?
the beaker would feel hot

How much does a beaker weigh with 40ml of water?
The weight of the beaker with 40mL of water will depend on the density of the water and the material of the beaker. Water has a density of 1g/mL, so the weight can be calculated by multiplying the density by the volume. The weight of the beaker itself will need to be accounted for as well.
Why does the beaker become misty?
Beaker is cold and when it meets the hot air it becomes foggy
What is used to pick up a hot beaker?
Beaker tongs or a hot mitt. See the Related Questions to the left for more information about tongs.

When you pour too hot or too cool water or ice in a beaker why the beaker will break?
Due to surface tension the beaker will break.
What of these items should be used to remove a hot beaker from a flame?
Tongs or heat-resistant gloves should be used to remove a hot beaker from a flame to prevent burns. Never use your hands directly to handle hot items in a laboratory setting.
Name 2 pieces of equipment you can use to boil a beaker of water in the lab?
a hot plate and a beaker
