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.
Cool Spot happened in 1993.
A beaker is placed in an ice bath to cool its contents rapidly by transferring heat from the beaker to the colder surroundings. This technique is commonly used in chemistry to control the temperature of a reaction or to promote the formation of crystals.
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.
Yes, condensation could form on the outside of a beaker full of hot water if the surrounding air is cool enough to cause the water vapor in the air to condense on the cooler surface of the beaker. This is similar to how condensation forms on a cold glass of water on a warm day.
Due to surface tension the beaker will break.
The beaker will eventually cool down, while the room will warm up. The room, having a much larger mass, will only warm up slightly.
I have seen beakers with filled capacities from 25 mL to 5 liters.
the rate of chemical weathering would slow down

Cool Cool Jam happened in 2000.
Cool Cool Toon happened in 2000.
The rate of evaporation of water from an open beaker can be decreased by placing a lid or cover over the beaker to reduce the surface area exposed to the air and prevent airflow. Additionally, lowering the temperature of the surroundings can help slow down the evaporation process. Adding solutes like salt to the water can also decrease the rate of evaporation.
Water droplets form on the inner surface of a beaker when the water vapor in the air comes into contact with a cold surface, causing it to condense into liquid water. This occurs due to the temperature difference between the cold surface of the beaker and the surrounding air.
Cool Riders happened in 1995.
Cool Boarders happened in 1996.
