. For quick preparation of a cup of hot chocolate in a cafeteria, cocoa powder and sugar

are added in a cup of water and the solution is heated by direct steam injection. If the

initial temperature of all the ingredients is 15 ℃, the final temperature is 95℃, the mass

of the solution is 150g initially, and the heat capacity of the solution is 3.8 kJ/kg ℃,

calculate how much saturated steam at 110 ℃ will be used. State your assumptions.

role play the problem solving scenario below, a dialogue between two characters. 

( scenario) two friend decided to work on a project group but one friend does not work. 

-Identify and analyse the problem ?

-Identify possible solutions ?

-using the scenario below and use 1st 2nd and 3rd person positions skills.

- uses appropriate self-disclosure.

- use high level of interaction management skills appropriate to the interaction including an appropriate balance of contributions from both parties.

Explain possible communication strategies and presentation methods that could be used to inform the stakeholders of the recommended solution
