In spiral model the main emphasis is on the management to evaluate and resolve risks in the software project. There is no maintenance phase in spiral model because instead risk is evaluated .
engineering phase
Not all models of software engineering are risky. The spiral model takes care of risk in every phase.
In the third or maintenance phase, the patient is relatively stable and can be kept indefinitely on antipsychotic medications. Even in the maintenance phase, however, relapses are not unusual
Modified waterfall model verified and validate the user requirements for every phase. Meanwhile, waterfall did not, it only verify and validate user requirement at the end of the phase.
In waterfall model, once we come out of the phase, there is no chance of modifying it again. This is one of the major drawback for waterfall model.
engineering phase
1.spiral model can be accommodate in prototyping and waterfall model. it is a model of iterative process as prototyping and also a systematic approach to solve a problem as in waterfall model. 2. spiral model take problem as a series of step to solve a problem as in waterfall, and take the contribution of users or customers in each phase as in prototyping model.

There are generally six stages, requirement analysis, design, implementation, testing, deployment and maintenance. Analysis is where the requirements are laid out so that the design phase can figure out how to best implement them. Implementation is where most of the work happens, leading to black and white box testing. After the testing phase, the product is rolled out to customers, and the maintenance phase is ongoing from that point on.
Conditioning Phase
Only during the maintenance phase
Not sure
phase of emulsion is two or more immiscible liquids.it contain two phases,dispersal phase and dispersal medium
itr ttrhh
yes
The testing phase consumes the maximum effort in waterfall model.
