Science

The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.

What acid react with KOH to produce the salt KCl?

User Avatar

Asked by Wiki User

Hydrochloric Acid (HCl), because HCl in aqueous solution form ions H^(+) & Cl^(-)

It is the Cl(-) anion that combines with then potassium cation to form that salt potassium chloride (KCl).

Here is the balanced reaction eq'n

HCl(aq) + KOH(aq) = KCl(aq) + H2O(l)

When did humans discover most of the scientific knowledge that Asimov describes in Science and the Sense of Wonder?

User Avatar

Asked by Wiki User

Humans have been gradually accumulating scientific knowledge over centuries through observation, experimentation, and collaboration. Much of the knowledge described by Asimov in "Science and the Sense of Wonder" was discovered through the work of scientists and scholars over the past few hundred years.

What are characteristics of boiling point?

User Avatar

Asked by Wiki User

The boiling point of a substance is a fundamental physical property characterized by several key features:

Temperature Specificity: The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid, causing the liquid to transition into a gas (vapor) throughout the substance, not just at the surface. This temperature remains constant for a pure substance under a constant pressure.

Pressure Dependence: Boiling points can change with variations in external pressure. At higher altitudes, where atmospheric pressure is lower, liquids boil at lower temperatures. Conversely, increased pressure can raise a liquid’s boiling point.

Purity Influence: The presence of impurities or solutes in a liquid can modify its boiling point. For instance, adding salt to water increases its boiling point, a phenomenon known as boiling point elevation.

Substance-Specific: Different substances have unique boiling points due to variations in molecular structure and intermolecular forces. Substances with strong intermolecular bonds, like ionic compounds, typically have higher boiling points.

Phase Change Indicator: The boiling point marks the temperature at which the liquid phase changes to the gas phase. During boiling, heat energy is absorbed to overcome the liquid's intermolecular forces, making it a phase change that occurs at a specific temperature, known as the latent heat of vaporization.

Latent Heat: At the boiling point, all heat energy supplied to a substance is used to convert it from liquid to gas without raising its temperature. This absorbed energy is called latent heat and varies for different substances.

Constant Temperature: When a liquid is boiling, the temperature remains constant until all the liquid has turned into a gas, assuming constant pressure and a single component system.

Identification Property: Boiling points help in identifying and characterizing substances and can be a crucial parameter in purification processes like distillation.

Understanding these characteristics of boiling points is vital for many practical applications, including chemical synthesis, cooking, distillation processes, and in the design of cooling and heating systems.

What does the auteur theory mean?

User Avatar

Asked by Wiki User

The auteur theory asserts that the director of a film is its primary author, influencing and shaping the film with their personal artistic vision and style. This theory suggests that a director's body of work can exhibit a consistent thematic and stylistic approach, making their films reflect their unique creative voice.

What material can change its shape easily?

User Avatar

Asked by Wiki User

Shape memory alloys, such as nitinol, are materials that can easily change their shape when exposed to heat or stress. These alloys have the ability to return to their original shape after deformation, making them useful in applications like orthodontic braces and stents.

How did the contribution of Rachel Carson made a difference in the science community?

User Avatar

Asked by Wiki User

Rachel Carson's contribution to the science community was significant in raising awareness about the harmful effects of pesticides, particularly DDT, on the environment and wildlife. Her book, "Silent Spring," played a key role in sparking the environmental movement and ultimately leading to the ban on DDT and the creation of the Environmental Protection Agency. Her work emphasized the importance of understanding the interconnectedness of ecosystems and the need for environmental conservation.

In what direction does heat travel through the soup?

User Avatar

Asked by Wiki User

Heat always travels from areas of higher temperature to areas of lower temperature. the surface and sides of a container of soup are generally at a lower temperature than the interior of the soup. Of course you may still get some additional heat transfer via convection if the surface is cooler than the soup deeper in the container.
