(a) 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 1 watt = 1 joule/second (1 w = 1 j/s)?

Heat required to raise the temperature is given by formula

here

now here first temperature of water and aluminium container raised to 100 degree C then water is boiled away.

heat is calculated by formula

PART b)

If power supplied is 500 W

then time taken to give such amount of heat is

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
