If, for example, your electric water kettle provided 75J of thermal energy to heat the water for every 100J of electrical energy consumed from the outlet, calculate the efficiency of your electric water kettle in heating the water (as a decimal).
Homework Answers
Efficiency is defined as the required output to the input provided .Here output is 75 joules of thermal energy and input is 100 joules of electrical energy
Therefore efficiency is 75/100=0.75 or 75 percent

A kettle of water has just boiled. At that moment the water inside contains roughly 775 kJ of thermal energy. a) After three hours resting on the counter, the water in the kettle has cooled to room temperature, losing about 170 kJ of thermal energy in the process. Where did that thermal energy go, and by what process(es)? b) Has the quality of the water’s thermal energy increased or decreased? Explain. You have just invented a new light bulb which...

A small electric immersion heater is used to heat 57 g of water for a cup of instant coffee. The heater is labeled "140 watts" (it converts electrical energy to thermal energy at this rate). Calculate the time required to bring all this water from 22°C to 100°C, ignoring any heat losses. (The specific heat of water is 4186 J/kg-K.) Number Units the tolerance is +/-2%

You want to make yourself some green tea, but the indicator on your (electric) kettle that lets you know the water has boiled does not work. You would like to put the kettle on and come back when the water has boiled. You know your kettlesupplies energy at a rate of 1025 W (1025 J/s). Assume water boils at 100°C. a. How long will it take, in seconds, to heat 0.8 kg of water from 15°C to the boiling point?...

(b) An ocean thermal gradient electric generating system (OTEC) is proposed for siting in Oman. This system would operate a heat engine driven by heat flow from warm ocean water (cooled from 27°C to 25 °C in the heating heat exchanger of the system), and cooled by heat flow to cold ocean water (which is heated from 3 °C to 5 C in the cooling heat exchanger of the system).
