How much heat transfer is required to raise the temperature of a 0.750-kg aluminum pot containing 2.50 kg of water from 30.0ºc to the boiling point and then boil away 0.750 kg of water? (b) how long does this take if the rate of heat transfer is 500 w

Part a)

Part b)

t = 4950.3 s

Explanation:

As we know that heat required to raise the temperature of container and water in it is given as

here we know that

now we have

now heat require to boil the water

here

m = 0.750 kg

now we have

Now total heat required is given as

Part b)

Time taken to heat the water is given as

here we know that

power = 500 W

now we have

helium

oxygen

neon

sodium
