Enthalpy is defined as the measure of energy in a thermodynamic system. The value of enthalpy is considered to be equal to the internal energy of the system and the product of pressure and volume. Calorimeter is usually used to obtain the value of enthalpy of a system. 
A coffee cup calorimeter is an effective way of measuring the enthalpy of a system because it is a constant pressure calorimeter. This means that, the heat that is measured in a coffee cup calorimeter is equivalent to the change in enthalpy; also its use result in little or no volume change to the system involved.

Based on my own opinion, i will say that From the "Boeing" mini-case in the Hill & Hult textbook, I do  think that Boeing's most recent decision to rethink its outsourcing strategy is correct.

<h3>Why did Boeing restructure and outsource the project operations?</h3>

The reason for the outsource is so that they can lower the  costs and and the time spent on development.

Note that  Boeing was known to have created about 787 through the use of a system that is said to be an unconventional three-tier supply chain.

Note that The implementation of this was said to have led to a substantial increase  in outsourcing.

Hence,  Based on my own opinion, i will say that From the "Boeing" mini-case in the Hill & Hult textbook, I do  think that Boeing's most recent decision to rethink its outsourcing strategy is correct.

4. Your city council gives All Talk Communication Services exclusive rights to build high speed internet infrastructure in your town.Government licencing

5. DeJeers Jewelers owns 80% of the world's diamond mines. Control over Resources

Explanation:

A monopoly is when there's only one firm operating in an industry.

Economies of scale is cost reduction that accures to a firm as a result of its large scale production. For example, a supplier might give a producer a discount for buying in bulk.

A patent is when the government or an agency of the government gives the right to produce an invention or a good for a set period, others are usually excluded making, using or selling the invention.

Copyright gives the owner of an intellectual property the exclusive right to make copies of a creative work, usually for a limited time.

If a firm has exclusive access to resocurces, it is possible for the firm to prevent other firms from entering into the industry and thus retain monopoly power.

I hope my answer helps you
