Kernels of popcorn were weighed and then heated to pop. Water escaped in the process of popping.   DATA DESCRIPTION TRIAL 1 TRIAL 2 Mass of Empty Evaporating Dish 35.6450g 35.6452g Mass of Evaporating Dish + Kernels Before Heating 42.3512 g 44.9572 g Mass of Evaporating Dish + Kernels After Heating 41.2540 g 42.6571 g   What is the average percentage of water in the kernels?     65.180%     28.719%     21.208%     3.8913%

When dry ammonia gas (NH3)is bubbled into a msp;125mLsample of water, the volume of the sample (initially, at least) decreases slightly. Suggest a reason for this.

In terms of their bulk properties, how do liquids and solids differ? How are they similar?

Consider a sealed container half-filled with water. Which statement best describes what occurs in the container? a. Water evaporates until the air is saturated with water vapor; at this point, no more water evaporates. b. Water evaporates until the air is overly saturated (super-por: at this point, no more water evaporates. Water evaporates until the air is overly saturated (supersaturated) with water, and most of this water recondenses; this cycle continues until a certain amount of water vapor is present, and then the cycle ceases. c. Water does not evaporate because the container is sealed. d. Water evaporates. and then water evaporates and recondenses simultaneously and continuously. e. Water evaporates until it is eventually all in vapor form. Explain each choice. Justify your choice, and for choices you did not pick. explain what is wrong with them.
