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.
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)
Where should a beaker be placed with respect to the flame for the most efficient heating on Bunsen burner?
The most efficient, and safe, place for a beaker to be heated is above the flame. Have the beaker held up by the proper metal stand and have it held so that the flame is grazing the bottom of the beaker. Be careful though, the flame should only graze the bottom of the beaker so that the chemical doesn't heat up too quickly.
What thermometer measures -specific heat of a substance -absolute temperature of substance -heat intensity?
specific heat thermometer
How can people tell the chemical reaction in a beaker?
Mostly by means of colour change and heat dissipated from 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
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
Why is it that an ice that is wrap in wire gauze does not melt when heated in a beaker of water?
Since the wire gauze is a good conductor of heat, all the heat is sttracted to the wire gauze
How do you heat a beaker of water?
With a heat source, slowly so as to not shatter the beaker.

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.
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.

Why do you have to use wire gauze in heating beaker?
the base of an evaporating dish is rounded and will not be stable when placed on a gauze, hence a triangle (tripod) to hold its base better . Also, when you heat the beaker, you put the wire gauze above the triangle(tripod) and the triangle(tripod) above the Bunsen burner.
