Which best describes why scientists need to be creative?

a. they need to be sure that the evidence backs up the conclusion.
b. they need to notice all of the evidence carefully.
c. they need to be constantly asking questions.
d. they need to think of ways to solve problems.

The answer is: c.They need to be constantly asking questions.

The scientific method is a process for experimentation that is used to explore observations.

Steps of the scientific method:

1) ask a question about something that is observed.

2) do background research.

3) construct a hypothesis, an attempt to answer questions with an explanation that can be tested.

4) test of hypothesis.

5) analyze collected data and draw a conclusion.

For example, Rutherford asked question about model of an atom.

Rutherford theorized that atoms have their charge concentrated in a very small nucleus.

This was famous Rutherford's Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles (helium atom particles, consist of two protons and two neutrons).  

Rutherford observed the deflection of alpha particles on the photographic film and notice that most of alpha particles passed straight through foil.

The correct answer is d.

Explanation:

Science is not a mechanical, routine activity. It is not subject to a rigid method. A scientific thought is all the more creative the more it moves away from the usual and routine practices in the scientific discipline in question. Scientists need to use their creativity to solve problems, since it is not always easy to come up with logical or structured answers. This allows the scientist to get out of his habitual thought to be able to understand the problem from different perspectives.

Have a nice day!

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
