Acombination of 0.250 kg of water at 20.0°c, 0.400 kg of aluminum at 26.0°c, and 0.100 kg of copper at 100°c is mixed in an insulated container and allowed to come to thermal equilibrium. ignore any energy transfer to or from the container and determine the final temperature of the mixture.

23.63 °C

Explanation:

= mass of water = 0.250 kg

= initial temperature of water = 20.0 °C

= Specific heat of water = 4186 J/(kg °C)

= mass of aluminum = 0.400 kg

= initial temperature of aluminum = 26.0 °C

= Specific heat of aluminum = 900 J/(kg °C)

= mass of copper = 0.100 kg

= initial temperature of copper = 100 °C

= Specific heat of copper = 386 J/(kg °C)

= Final temperature of mixture

Using conservation of heat

( - ) + ( - ) + ( - ) = 0

(0.250) (4186) ( - 20) + (0.400) (900) ( - 26) + (0.100) (386) ( - 100) = 0

= 23.63 °C

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
