A student decides it is possible to estimate the capacity of a test tube by treating it as a rectangle and neglecting its roundness. On this basis, the student finds the capacity of the test tube to be 100.5 ml. In fact, the real capacity of the test tube is 100.0 ml. What percent error has resulted from the studentās assumption?

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60Ā°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280Ā°f and a minimum temperature of 240Ā°. once the temperature hits 280Ā°, it takes 20 minutes before it is 280Ā° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270Ā°. he puts the cake into the oven when it is at 260Ā° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)
