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.

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?

What is the measure of how much matter is in an object and that can be measured using a balance? a. height b. volume c. weight d. mass
