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 shouldn't the thermometer touch the walls of the distillation head?
because the sides of the beaker will be slightly at high temperature
What materials is beaker made of?
an example is! a small cylinder with a small opening
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.
When ammonium chloride dissolves in a beaker of water the beaker becomes cold to the touch explain this phenomenon?
When the ammonium chloride dissolves in the water, it is an endothermic reaction. The energy for the reaction comes from the water. Since the water is losing energy, the temperature of the solution decreases, which in turn decreases the temperature of the beaker because of heat transfer.
When sodium metal is dropped into a beaker of water a chemical reaction occurs that increases the temperature of the water This is an example of what?
You think probable to an exothermic reaction.
If the temperature after a reaction is higher is the reaction endothermic or exothermic?
If the temperature rises, the reaction is EXOTHERMIC where the system (reaction) is giving off heat to the surroundings (water, beaker, test tube, etc.).
What is the temperature of the beaker holding the reacting substance decrease is it endothermic or exothermic?
The way I remember it: endo (think in). Heat is flowing in to the reaction from the surroundings. Heat flows from hot to cold, so the measured temperature decreases. The actual beaker will decrease temperature as well, since it is next to something that has decreased in temperature.
Uses of a watch glass?
For example to contain a sample to be weighed; or to make a chemical reaction at small scale; or to cover a beaker.
A reaction is taking place in a beaker and the outside of the beaker goes very cold What kind of reaction is taking place?
Endergonic/endothermic
Why does the beaker become misty?
Beaker is cold and when it meets the hot air it becomes foggy
If you pour germinating peas in a beaker and boiled peas in another in which beaker will the temperature rise?
beaker x
What is the principle of water bath?
The water bath is used in the lab to allow a chemical reaction to occur at a specific temperature. The bath is heated to a precise temperature and the beaker or other container is placed in the bath.
Is it a exothermic reaction when a beaker of water in the sunlight turns warm?
Warming is not a reaction.
What is the chemical reaction when you burn a candle inside a glass beaker?
It is an oxydation reaction.
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
