what is the purpose of making observations in the scientific method
to gather data and information
to prove the hypothesis
to develop a conclusion
to form a bias
The purpose of making observations in the scientific method is to gather data and information about a particular phenomenon or topic. These observations help researchers to collect objective and measurable information, which can then be used to analyze and interpret the results of an experiment or study. The observations made during the scientific method are used to support or reject a hypothesis, develop a conclusion, and form unbiased and objective conclusions. So, the purpose is primarily to gather data and information, rather than to prove the hypothesis or just form a bias.
which of the following is a limitation of scientific models
there are too simple to represent a complex phenomenon
they are always 100% accurate in their predictions
they cannot be modified or improved on
they are only used in theoretical research
The limitation of scientific models is that they are too simple to represent a complex phenomenon. Scientific models are simplified representations of real-world systems or processes, and they necessarily omit certain details in order to make them easier to study and understand. Therefore, they may not capture the full complexity of the phenomenon they are attempting to represent. It is incorrect to say that scientific models are always 100% accurate in their predictions or that they cannot be modified or improved upon; both of these options are inaccurate. Additionally, scientific models are not limited to theoretical research; they are used in a wide range of scientific fields and applications, including practical experiments and simulations.
two solid blocks are heated to the temperature shown the blocks are placed so they touch Which diagram shows the direction heat will flow
Box A shows two boxes stuck together on the left being 160 C on the right being 141 C, the heat flow is traveling to the left
Box B shows two boxes stuck together on the left being 160 C on the right being 141 C, the heat flow is traveling to the right
Box C shows two boxes stuck together on the left being 160 C on the right being 141 C, there is not heat flow
Box A
Box B
Box C
The correct answer would be Box A. When two solid blocks are in contact and at different temperatures, heat will flow from the hotter block to the colder block. In this case, since the block on the left is at 160°C and the block on the right is at 141°C, heat will flow from the left block to the right block. Therefore, the heat flow is traveling to the left, as shown in Box A.
which of the following is an example of a mixture
water
salt
oxygen
gas air
A mixture refers to a combination of two or more substances, each of which retains its own chemical properties. Among the options you provided, the example of a mixture is gas air. Gas air is a combination of different gases, such as oxygen, nitrogen, carbon dioxide, and others. This mixture has varying proportions of these gases and can be separated into its individual components. Water, salt, and oxygen are not examples of mixtures as they are pure substances; water is a compound, salt is an ionic compound, and oxygen is an element.
just answer with what i gave you
Water.
