Scientific Method

The scientific method is the basis of scientific investigation. A scientist will pose a question and formulate a hypothesis as a potential explanation or answer to the question. The hypothesis will be tested through a series of experiments. The results of the experiments will either prove or disprove the hypothesis. This category should contain questions and answers regarding the scientific method.

Asked by Wiki User

The state of matter that has particles that slide by one another is called a liquid. In liquids, the particles are close together but can still move past each other, giving liquids their ability to flow and take the shape of their container.

Why does dust comes out from a carpet when beaten with a stick?

User Avatar

Asked by Wiki User

When you beat a carpet with a stick, the impact dislodges dirt, dust, and debris trapped in the fibers. The force causes these particles to become airborne and visible. Regularly beating a carpet helps remove accumulated dirt and maintain its cleanliness.

What variables do you need to control in your experiment if i wanted to find the effect of light on tamatoes?

User Avatar

Asked by Wiki User

To find the effect of light on tomatoes, you would need to control variables such as the type and intensity of light, the duration of light exposure, the temperature of the environment, the type of soil and nutrients used, and the watering schedule. By controlling these variables, you can ensure that any changes observed in the tomatoes can be attributed to the presence or absence of light.

What is an isochore map?

User Avatar

Asked by Wiki User

An isochore map is a visualization tool that displays areas with similar thicknesses of sediment or rock layers in a specific region. These maps are commonly used in geology and petroleum exploration to identify areas with potential for oil and gas reservoirs based on the variations in rock thickness.

How does water molecules move through the water cycle?

User Avatar

Asked by Wiki User

Water molecules move through the water cycle by evaporating from bodies of water into the atmosphere, condensing into clouds, falling back to Earth as precipitation, and then either infiltrating into the ground to become groundwater or running off into bodies of water such as rivers and oceans. This continuous process of evaporation, condensation, and precipitation is what drives the water cycle.

Will the temperature of a beaker of water increase or decrease when it is mixed with sodium chloride?

User Avatar

Asked by Wiki User

The temperature of the water will decrease when mixed with sodium chloride because it is an endothermic process. Sodium chloride dissolves in water, breaking bonds and absorbing energy from the surroundings, leading to a decrease in temperature.

What is the scientific formula of air?

User Avatar

Asked by Wiki User

Air is a mixture of gases, primarily nitrogen (N2) at 78% and oxygen (O2) at 21%. It also contains small amounts of other gases like carbon dioxide (CO2), argon (Ar), and trace amounts of water vapor. The precise composition of air can vary depending on location and altitude.

What are the different substances and mixtures in scientific method?

User Avatar

Asked by Wiki User

In the scientific method, substances refer to pure, homogeneous materials like elements or compounds, while mixtures are combinations of different substances that can be separated by physical means. Substances are typically used in experiments to observe their properties and behavior, while mixtures may be investigated to understand their composition and interactions. Both substances and mixtures play key roles in scientific research and experimentation.

How do you make a conclusion about the reaction between hydrochloric acid and magnesium?

User Avatar

Asked by Wiki User

To make a conclusion about the reaction between hydrochloric acid and magnesium, you can observe the bubbling or fizzing that occurs as hydrogen gas is produced. You can also collect the gas in a test tube and test it with a lit match to confirm that it is hydrogen gas. Additionally, you can measure the temperature change of the reaction as an indication of energy being released.

What is the structure of a controlled experiment?

User Avatar

Asked by Wiki User

A controlled experiment involves manipulating one variable (independent variable) while keeping all other variables constant, to observe the effect on another variable (dependent variable). This is typically done by having an experimental group that receives the treatment and a control group that does not, allowing for comparison between the two groups. Random assignment and replication are key components to ensure the validity and reliability of the results.

What are the limitation of using false position method?

User Avatar

Asked by Wiki User

Some limitations of the false position method include its slow convergence rate when the bracket interval is wide, the method may fail if the function is not well-behaved (e.g., has sharp turns, multiple roots), and it may require a large number of iterations to reach the desired accuracy in some cases.

How does the temperature of a substance change as it gains or loses heat?

User Avatar

Asked by Wiki User

When a substance gains heat, its temperature increases as the heat energy is added to the internal energy of the particles, causing them to move faster. When a substance loses heat, its temperature decreases as the heat energy is released from the internal energy of the particles, causing them to slow down.
