(a) How much heat transfer (in kcal) is required to raise the temperature of a 0.650 kg aluminum pot containing 2.00 kg of water from 50.0°C to the boiling point and then boil away 0.800 kg of water? kcal (b) How long (in s) does this take if the rate of heat transfer is 550 W (1 watt = 1 joule/second (1 W = 1 J/s))?
Here,
for the total heat needed
a) total heat input
total heat input = 0.650 * 900 * (100 - 50) + 2 * 4186 * (100 - 50) + 0.80 * 2260 *10^3
total heat input = 2255850 J
the total heat input is 2255850 J = 538.9 Kcal
the total heat input is 538.9 Kcal
b) let the time taken is t
Power * t = total heat input
550 * t = 2255850
t = 4101 s
the time taken is 4101 s
