But the more computing power that goes into the model and the care with which the scientists construct the model can increase the chances that a model will be accurate.  Having read the above passage, choose the right answer to the following question (choices are increase or decrease ):   Mona is developing a computerized model to detect changes in weather patterns for her farming business. If she removes computing power from the computer she is using to develop the model, what happens to the chances that model will be correct increase or decrease?
decrease

The more branching there is in isomers, the lower the boiling and melting points are.  Having read the above passage, choose the right answer to the following question (choices are decrease them or increase them ):   If Jim is trying to lower the melting point of an isomer, what should he do to the number of branching points of the isomer decrease them or increase them?
increase them

Q: Alkanes with more carbon atoms have higher boiling and melting points, so some of them are solids at room temperature.  Having read the above passage, choose the right answer to the following question (choices are alkane with fewer carbon atoms or alkane with more carbon atoms? ):   Kathy did some experiments on two different alkanes and one of the alkanes had twice as many carbon atoms than the other. She would notice that which alkane would require a lower temperature to melt alkane with fewer carbon atoms or alkane with more carbon atoms??
A: alkane with fewer carbon atoms

Question: At higher concentrations, particles of reactants are crowded closer together, so they are more likely to collide and react.  Having read the above passage, choose the right answer to the following question (choices are increase or decrease ):   As we fill a balloon with air the number of reactions in the balloon increase or decrease?
Answer: increase
