Students design an experiment to find out how changing the volume of water in a cup affects the force needed to drag it across a rough surface. The diagram shows the students' experiment. Drag the variable(s) and constant(s) to the appropriate places in the table.

As shown in fig. p3.64, a closed, rigid tank fitted with a fine-wire electric resistor is filled with refrigerant 22, initially at 2108c, a quality of 80%, and a volume of 0.01 m3. a 12-volt battery provides a 5-amp current to the resistor for 5 minutes. if the final temperature of the refrigerant is 408c, determine the heat transfer, in kj, from the refrigerant.
