Maybe useful information: GENERAL ELECTRIC CO. LOUISVILLE, KY. 40225 HOUSEHOLD MICROWAVE OVEN 0: LISTED MODEL NO. SERIAL NO MANUFACTURED October 1999 JE1360WB 001 TV 919297K KW: 1.53 VALİZ : 12060 FCC ID BEJSI24X0 MADE IN KOREA DHHS CODE NO GC 1 YEAR LIMITED CARRY-IN PAO . THIS PRODUCT COMPLIES WITH DHHS RULES 21 CFR SUBCHAPTER J. . This is a picture of the microwave information plate often found on the inner wall of your microwave Approximately 1 cup of water = 250 mL 0.250 kg water . 1 kJ -1000 J and 1kW 1000 W . The definition of power in physics is the rate by which energy is transferred. The units of Power are Watts = Joule / second. Specifically Where P is power, Q is heat, and t is time in seconds. The Big Question: How much does approximately a cup of water increase in temperature when heated in a microwave for 45 seconds? We'll answer this Big Question in steps: a) Use the microwave information plate to determine how much energy the microwave uses when turned on for 45 seconds. Hint: use the microwave information plate to get the power rating of the microwave. Then use the algebraic representation of power above to determine Q. b) Assuming all the energy of the microwave goes into the water, create a model that predicts the change in temperature of the water. c) Carryout the necessary calculations to get an answer to the Big Question.
