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.

What will a thermometer show if placed next to a beaker containing an exothermic reaction?

The exothermic reaction within the beaker releases heat energy, resulting in an increase in temperature of the materials inside the beaker.Now about the dispersion of the heat energy.Conduction: The beaker molecules and air molecules in touch with the heated material inside the beaker heat up by conduction and will continue spreading this heat in all directions.Via Convection: The heated air above the reacting materials rises, thus dispersing the heat via convection.Radiation: Any and all heated materials disperse heat via radiation. This type of heat transfer requires no medium.How far and how much energy is transferred depends on different variable, including the amount of energy given off by the exothermic reaction as well as the materials in the beaker, and air density.As to the dispersed heat affecting a thermometer placed next to the beaker---There are so many variables not given in the question.Is the thermometer bulb measuring air temperature? if so, is the heat given off by the exothermic reaction enough to raise the air temperature surrounding the thermometer bulb? If so, then the answer is that the thermometer will report a higher temperature reading.


Why will the mercury in the thermometer rise after 3 minutes?

The mercury in the thermometer will rise after 3 minutes because it expands when exposed to heat. As the thermometer absorbs the heat of the environment, the mercury inside it will expand and move up the tube, indicating a higher temperature.


What thermometer measures -specific heat of a substance -absolute temperature of substance -heat intensity?

specific heat thermometer


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)


What do you use to heat a beaker on a tripod?

A Bunsen burner is commonly used to heat a beaker on a tripod in a laboratory setting. It provides a controlled flame for even heating.

How do you heat a beaker of water?

With a heat source, slowly so as to not shatter the beaker.

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 does heat reach water in a saucepan that is on a heated stove?

by boiling


What equipment is needed to heat water with a Bunsen burner?

To heat water with a Bunsen burner, you would need a Bunsen burner, a heat-resistant container to hold the water such as a beaker or flask, a tripod or wire gauze to support the container over the flame, and a source of water to be heated. Optional equipment could include a thermometer to monitor the temperature of the water.


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 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.


Why should a thermometer not touch the sides of the test tube and should be placed in the middle?

If you place the thermometer so it touches the sides of the test tube, you are measuring the temperature of the test tube, not the substance in the test tube. So, in order to get an accurate reading of the substance, do not touch the sides of the test tube with the thermometer.


What is the difference between a heat thermometer and a regular thermometer?

There is no difference between a heat thermometer and a regular thermometer. A thermometer measures the average kinetic energy of something, also known as heat. A thermometer's purpose is to measure heat, so a regular thermometer is the exact same thing as a regular thermometer, just with different names.

The mercury in the thermometer will rise after 3 minutes because it expands when exposed to heat. As the thermometer absorbs the heat of the environment, the mercury inside it will expand and move up the tube, indicating a higher temperature.


Why did the temperature recorded by lower thermometer continue to rise dramatically after the heating ceased?

The lower thermometer continued to rise dramatically after the heating ceased due to a phenomenon called thermal lag or hysteresis. This occurs because the lower thermometer takes time to adjust to the changes in temperature in its environment. Additionally, heat may still be transferring from the heated area to the lower thermometer even after the heat source is removed.
