Why do beaker need to cool before weighing?
A hot beaker warms the air around it, which causes it to rise. For very sensitive balances, the updraft produced can reduce the measured weight.
When did Cool Spot happen?
Cool Spot happened in 1993.
What is the best way to make supersaturated solution?
Use really clean equipment. Heat some water in a beaker so that it will dissolve more solute. Dissolve all that it will hold, to make sure add excess. Decant the liquid into another beaker allow no crystals to be transferred to the new beaker. Allow to cool slowly. Do not agitate. The cool solution will be supersaturated.
What happens when a beaker containing reactants is cooled?
The room temperature water in the hot beaker turns into hot water (not boiling) if the beaker is hot enough.
Is evaporation an exothermic or endothermic process explain?
It will be an endothermic process because the beaker becomes cool after evaporation.
How can the rate of evaporation of water from an open beaker be decreased?
Place a lid over the beaker, and store in a cool place.
When you pour too hot or too cool water or ice in a beaker why the beaker will break?
Due to surface tension the beaker will break.
What will happen to beaker temperature of 75 degrees celsius in a room temperature of 36 degrees celsius?
The beaker will eventually cool down, while the room will warm up. The room, having a much larger mass, will only warm up slightly.
How is water droplets formed in the inner most surface of the beaker?
when the hot water in the beaker touches the cool surface of the beaker,the water condenses into water droplets.
What is the volume of a beaker?
I have seen beakers with filled capacities from 25 mL to 5 liters.
What would you expect to happen if you moved a marble statue from a hot wet climate to cool dry climate?
the rate of chemical weathering would slow down
