nves Title of the Project: Frozen Hot Ice Cream Rationale: We have encountered a phenomenon that states that the hotter liquid freezes faster than cold liquid. This phenomenon has been known for a long time‚ but was rediscovered by a Tanzanian high school student‚ Erasto Mpemba‚ in the 1960s. He and his classmates were making ice cream‚ using a recipe that included boiled milk. The students were supposed to wait for the mixture to cool before putting it in the freezer. The remaining

not be insulated‚ but they would freeze solid along with the pond from the bottom up. Ice-skating is another thing that would be impossible for this very same reason. An interesting phenomena that has much to do with the expansion of water when it freezes are "ice spikes". These are small structures of ice that grow out of pure water when frozen at a temperature just below 0° C. What these structures resemble are upside down icicles. As the water freezes‚ it freezes from top to bottom‚ and outside

EXECUTIVE SUMMARY In the current scenario‚ the major bottlenecks in the system are the drying units for wet berries and the berry separation lines. While the drying units’ capacity can be increased by purchasing additional units‚ the throughput of the system will still be limited by the limitation of the separation lines. If the average rate of inflow of berries is 1500bbl/hr‚ then with the effective separation capacity of 1200bbl/hr‚ the plant will incur a backlog of 300bbl/hr. If the shift start

It is most effective in cold or upland areas of the world where temperatures move above and below freezing point (0°C)‚ creating a frost cycle. Freeze-thaw is most effective on rocks that have joints‚ fractures and pore spaces.Water fills the spaces in the rock during the day‚ when temperatures are warmer. The water freezes if the night-time temperatures drop below

DEFINITION OF HANDWASHING: A fundamental part of standard precaution procedures and disease control for dental personnel; helps reduce or prevent infection and transmittal of microbes among people and objects; for regular dental procedures‚ liquid soap and water is sufficient but for surgical procedures‚ antimicrobial cleansers should be used.

Purpose Sentence The purpose of this speech is to inform my listeners on how to do laundry. Introduction Forty-five percent of children don’t learn how to do laundry until leaving for college. Most children feel that it’s not a necessary tool they need to know until they are on their own. Having freshly cleaned pants and blouses each day in your closet seems normal to many kids‚ but before you know it‚ those wonderful days will in fact be over. After today‚ most of you

STROKE(cerebrovascular accident/Disambiguation) A stroke‚ or cerebrovascular accident (CVA)‚ is the rapid loss of brain function(s) due to disturbance in the blood supply to the brain. This can be due to ischemia (lack of blood flow) caused by blockage (thrombosis‚ arterial embolism)‚ or a hemorrhage. As a result‚ the affected area of the brain cannot function‚ which might result: In an inability to move one or more limbs on one side of the body. Inability to understand or formulate
