If beaker a had 250ml of water beaker b had 500ml water are warmed from 10 celsius to 20 celsius what one requires more heat?
Because there is a greater volume of water in beaker B, the beaker would have to be heated for a longer period of time to reach the same temperature as beaker A. If your desire is to have both beakers warmed to the same temperature at the same time, beaker B would require the addition of more heat (because there is more water inside it).
How do you heat liquid in a beaker?
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 burnerfor controlled temperature a water or glycol bathimmersion heatersmicrowave heaterselectric coils under the beaker
Why do hot beakers crack in cold wale?
im assuming you meant to type water... this happens because heat makes things expand, whilst cold makes things contract. by putting a hot beaker in cold water, you put too much strain on the beaker because it is changing size so fast
Some students were watching an ice cube in a beaker as it slowly melted They were wondering why it melts When they inspected the beaker the next lesson the water was gone?
ICE REQUIRES A TEMPERATURE OF 0 DEGREES TO REMAIN IN THE SOLID STATE. IF THE ATMOSPHERIC TEMP. IS GREATER, IT ABSORBS THE SURROUNDING HEAT AND IS CONVERTED TO WATER. LATER, EVAPORATION CAUSES IT TO STEAM AND IT DISAPPEARS.
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.
Beaker A contains water at a temperature of 15 degrees C beaker B contains water at a temperature of 37 degrees C Which beaker contains water molecules that have greater kinetic energy and why?
Beaker A: 15 C Beaker B: 37 C Beaker B contains water molecules that have the greater kinetic energy (on average). Since beaker B is at a higher temperature than beaker A, the water molecules must be moving faster in beaker B than in beaker A (on average). If heat is being applied to the beakers, then the increased amount of heat applied to beaker B is greater, and the heat will cause the water molecules in beaker B to move faster than the water molecules in beaker A (on average). Kinetic energy = (1/2) (mass) (velocity)^2 Since the velocity of the a water molecule in beaker B is on average greater than the velocity of an average water molecule in beaker A, the water in beaker B has a higher kinetic energy.
In a beaker sugar is dissolved in water and then the water is heated and evaporates The sugar is recovered and heat is again applied Vapor is released and the material in the beaker changes from?
In a beaker, sugar is dissolved in water, and then the water is heated and evaporates. The sugar is recovered, and heat is again applied. Vapor is released, and the material in the beaker changes from white to black. What must you know to determine if a chemical change occurred? CO2 (carbon dioxide) CuO (oxidized copper) H2O (distilled water) H2O2 (hydrogen peroxide) NaCl (sodium chloride)
How do you heat a beaker of water?
With a heat source, slowly so as to not shatter the 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 happends when methane burns?
The production of water and carbon dioxide and the release of heat energy.

What is the best way to heat a beaker of water on a Bunsen burner?
The best way to heat a beaker of water on a Bunsen burner is to adjust the air hole to get a blue flame, place the beaker on a wire gauze to distribute heat evenly, and continuously stir the water with a glass rod to ensure uniform heating. Additionally, you should monitor the temperature with a thermometer to prevent overheating.
How much heat (calories) must be applied to a 10ml beaker filled with boiling water in order to vaporrize the water?
I guess none. Why? The given is that the water is boiling -- it is turning into vapor.
What factors affect the rate at which Bunsen burner heats water in a beaker?
The rate at which a Bunsen burner heats water in a beaker is affected by factors such as the size of the flame, proximity of the flame to the beaker, the material of the beaker, and the starting temperature of the water. Additionally, the efficiency of the heat transfer process can be influenced by the presence of a lid or stirrer in the beaker.
How is heat being transfered when you place your finger in the cold beaker why?
If the beaker has a cold water, or something else cold, in it than the heat that is in our finger will run out of you finger into the cold water. This leaves your finger 'empty' of heat, giving you the sensation of being cold. You need to remember that only heat moves. When you are cold you wear a jumper that keeps the heat in your body, not keep the cool out.
Which item decreases as heat is applied?
Volume is increased so density is decreased.
What happends when you heat an acid?
you get a chemical reaction.
