In a laboratory there are several methods to heat liquids in beals or other glassware depending on the temperatures you wish to attain and the control you wish to have over the temperature,
- For rapid heating a stand supporting the beaker over a Bunsen burner or Maker burner
- for controlled temperature a water or glycol bath
- immersion heaters
- microwave heaters
- electric coils under the beaker
What else can I help you with?
What is the usage of beaker?
The purpose is to measure liquids and to boil it on your burner because of the big flat bottom and so you can pour the liquid a little more accurately when trying to do like a small drop of something.
What happens when an object is dropped into a beaker containing a liquid and then the object drops to the bottom of the beaker?
The density of the object is at least equal to, and possibly greater than, the density of the liquid in the beaker.
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?
Why is a beaker called beaker?
It measures the amoun of liquid you have.
What are the little lines on the beaker?
measurements so that if you fill it with liquid, you can tell how much
What is used to heat large amounts of liquid in science?
A Beaker
How do you heat a liquid to 90 degrees?
if your in a lab, put water in a beaker, place the beaker on a tripod and heat with Bunsen burner, (use thermometer to measure
What happens to acetone molecules when you add heat to a breaker of liquid acetone?
When heat is added to a beaker of liquid acetone, the acetone molecules gain energy and begin to evaporate into the air as a gas. The increased temperature causes the molecules to move faster and escape the liquid phase.
Can a beaker that contain more liquid but same amount of heat cool first?
Yes, a beaker containing more liquid can cool down first if it has a larger surface area or if the heat loss mechanisms, such as evaporation or convection, are more efficient in that beaker. Additionally, the specific heat capacity of the liquid and the environmental conditions can also influence the cooling rate. Generally, a larger volume of liquid may retain heat longer due to its greater thermal mass, but specific circumstances can lead to it cooling more quickly.
Why do the beaker most likely feel warm?
The beaker most likely feels warm because it has been in contact with a warm or hot substance, such as a heated liquid or a hot plate. Heat transfer has caused the beaker to absorb some of the heat energy, resulting in the sensation of warmth.
What changes occur as you slowly heat a beaker of ice?
As you heat a beaker of ice, the ice will begin to melt and turn into liquid water. The temperature will slowly rise until it reaches a point where all the ice has melted. After that, the temperature will continue to rise as the liquid water heats up.
What is the usage of beaker?
The purpose is to measure liquids and to boil it on your burner because of the big flat bottom and so you can pour the liquid a little more accurately when trying to do like a small drop of something.
If a liquid is added to a beaker the pressure exerted by the liquid on the bottom of the beaker?
increases due to the increased weight of the liquid. This is because the liquid's weight creates a force that is spread out over the bottom of the beaker, leading to an increase in pressure.
When measuring the mass of liquid in a beaker subtract the?
You must obtain and subtract the mass of the beaker.
What is the Control variable when you blow into a beaker with a straw with liquid in it?
The control variable in this scenario would be a beaker with liquid in it that is not being blown into with a straw. This serves as a baseline for comparison to see the effect of blowing into the beaker with a straw on the liquid.
A beaker has a mass of 200 grams what is the mass of a liquid if the beaker plus the liquid have a mass of 286 gram?
86 g
How does the heat reach the thermometer in the heated beaker?
Heat reaches the thermometer in the heated beaker primarily through conduction and convection. As the beaker is heated, the water molecules gain energy and transfer that energy to the thermometer through direct contact. Additionally, as the warmer water rises and cooler water descends, convection currents help distribute heat throughout the liquid, ensuring that the thermometer accurately reflects the water's temperature. This process allows the thermometer to register the temperature of the liquid efficiently.
