Based on the temperature data in the table which chemical reaction should the students use for their food carrier design
Sladkaya [172]

Answer:

Reaction 1

Explanation:

Reaction 1 would be the most suitable in this case. This is so because in reference to the question you are wanting to keep the food warm over long periods. So in reference to the data in the chart reaction 1 continues to heat up over long periods of time. However, with the other reactions (2, 3, 4) temperatures vary and some even decrease constantly. Therefore showing that the other reactions are invalid to help reach your goal referencing back to the question.

De acuerdo a lo visto en clases, de los siguientes elementos señale 3 que no pueden estar ausentes en una célula.
Rama09 [41]

Answer:

The nucleus, cell membrane and cytoplasm.

Explanation:

The nucleus, cell membrane and cytoplasm are three elements that cannot be absent in a cell because they are necessary for the survival of the cell. The nucleus controls and regulates the activities happening inside the cell e.g. growth and metabolism etc. Cell membrane acts as a wall to protect the inner part of the cell from the external environment as well as allows nutrients and gases inside and outside the cell. Cytoplasm serves as a medium for the conduction of nutrients and waste from on place to another and also for the medium for organelles in which they floats.

Why is the back-work ratio much higher in the brayton cycle than in the rankine cycle?
Ivanshal [37]

The back-work ratio much higher in the brayton cycle than in the rankine cycle because a gas cycle is the Brayton cycle, while a steam cycle is the Rankine cycle. Particularly, the creation of water droplets will be a constraint on the steam turbine's efficiency. Since gas has a bigger specific volume than steam, the compressor will have to work harder while using gas.

Recall the steady flow device's shaft work expression.

W =-∫ V dP +...

As it is in the pump (liquid) compared to turbine (superheated vapor) in the Rankine cycle, the specific volume in the compressor is not significantly less than the specific volume in the turbine in the Brayton cycle.

A thermodynamic cycle that transforms heat into mechanical energy is the Rankine cycle, often known as the Rankine vapor cycle.

The operation of various heat engines that use air or another gas as their working fluid is described by the Brayton cycle, a thermodynamic cycle.
