current of 1.98 A when connected to the 220 V mains supply. If all the energy produced in 2.19 minutes is used to heat 2.08 kg of water, determine the rise in temperature of
An electric heating device consumes
the device.
(Specific heat capacity of water = 4200 J kg1 K-1)
Note:
- Express your answer in 2 decimal places.
- No need to include the unit in the answer field.
- Final answer should be in °C
An electric heater works by passing a current of 100 A
though a coiled metal wire, making it red hot. If the
resistance of the wire is 1.1 ohms, what voltage must be
applied to it?
A heater is placed in 5 liters of ethanol, which has a specific heat capacity of 2.44 joules per gram kelvin and a specific gravity of 0.7893.
Assume the initial temperature of the ethanol is 70 degrees Fahrenheit, the heater is powered by a voltage of 240 volts at a current of 500 milliamperes, and the transfer of energy to the ethanol as heat has an efficiency of 45%.
How long must the heater operate to raise the temperature of the ethanol to 95 degrees Fahrenheit? Express your answer in units of minutes.
