What else can I help you with?
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).
What materials is beaker made of?
an example is! a small cylinder with a small opening
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 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 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.
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.
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.).
A reaction is taking place in a beaker and the outside of the beaker goes very cold What kind of reaction is taking place?
The reaction is likely an endothermic reaction. In an endothermic reaction, heat is absorbed from the surroundings, causing a decrease in temperature.
How does is the temperature of beaker measure in water?
The temperature of a beaker is typically measured using a thermometer that is placed in the water inside the beaker. The thermometer will provide a reading of the water temperature, which indirectly reflects the temperature of the beaker as well.
How can people tell the chemical reaction in a beaker?
People can tell a chemical reaction is occurring in a beaker by observing changes such as color, gas production, temperature change, formation of a precipitate, or the release of light or sound. These visual clues can indicate that new substances are being formed due to the chemical reaction taking place.
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.
What happens when a beaker containing reactants is cooled?
When a beaker containing reactants is cooled, the reaction rate typically decreases because lowering the temperature reduces the kinetic energy of the reactant molecules, slowing down their movement and collision frequency. This can result in a slower reaction rate and potentially a longer reaction time to reach completion. The equilibrium position of the reaction may also shift depending on the specific reaction conditions.
Why does the beaker become misty?
Beaker is cold and when it meets the hot air it becomes foggy
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
How does condensation appear on the outside of a beaker?
Condensation appears on the outside of a beaker when the temperature of the surrounding air is lower than the temperature of the contents inside the beaker. This temperature difference causes the moisture in the air to condense on the colder surface of the beaker, forming water droplets.
