An iron boiler of mass 230 kg contains 830 kg of water at 18c.
a heater supplies energy at the rate of 52,000 kj/h. how longdoes
it take for the water a) to reach the boiling point, and b) toall
have changed to steam?

The total time is 41.38 hours.

Explanation:

Given that,

Mass 230 kg

Mass of water = 830 kg

Temperature = 18 C

Rate of energy supplied = 52000 Kj/h

Let the boiling temperature of the water be 100°C

(a). We need to calculate the energy

So from the principle of calorimeter

Put the value into the formula

We need to calculate the time

Using formula of energy

Put the value into the formula

(b). There is no change in temperature.

So the additional heat required to change the water into steam is

We need to calculate the energy

Using formula of energy

We need to calculate the additional time

Using formula of additional time

Put the value into the formula

We need to calculate the total time

Using formula of time

Put the value into the formula

Hence, The total time is 41.38 hours.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
