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.
If you place iodine in a beaker of H2O will it float?
no..
Is steam water vaouper?
Yes, it is. As steam is given of, if you get a plastic bag and place it over the top, you catch water vapour and you will see water droplets inside it.
Why is it important to place the developing solvent in a clean dry beaker?
So it doesn't get contaminated with dirt.
How do you measure the volume of an irregular object?
Place it in a graduated cylinder (or any other metered container), completely submerge the object, and record the amount of water displaced. ---------------------------------------------------------------------------------------- Place an empty beaker onto a second larger catch pan. Be sure that your catch pan will hold water without leaking, and make sure it is large enough to catch ALL of the water that will spill out of the beaker. Fill a beaker until you can see the meniscus above the rim of the container. CAREFULLY lower your irregular object into the beaker with water allowing the beaker to over flow into the catch pan. Once you have your object submerged in the beaker, remove the beaker from the catch pan. Let the little bit of water adhered to the exterior of the beaker drip into the catch pan for a few seconds to make your measurement as accurate as possible. Using a graduated cylinder, measure the volume of water that has over flowed into your catch pan. The volume of this water will be very close to the volume of your irregular object.
What collects on the outside of the beaker if you place a 5 ml water and few ice cubes in the beaker?
when ice cubes place in the beaker, outside of the beaker have a formation of water drops. by. JD
