A student wants to design coasters that can prevent hot drinks from damaging a table due to transferring heat to the table. The student makes a circular coaster by cutting out a piece of cardboard 1 mm thick and placing a glass with hot water on top of it. After a while, the student observes that the table surface just below the coaster becomes warm. The image shows the setup for testing the coaster.

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.
