When you change the shape you are also changing the density of the object, like for instance if you take a paper boat and put it into water it will float, but if you shape something into a ball it becomes compact and will sink. that is because its weight is more than what the displaced water weighs.

In its simplest definition Dialectic means instructional (for aseverely more complex definition see wikipedia) . A Dialectic Responce journal then would be a journal that a student keeps to respond to his instruction.

eg. Socrates drank Hemlock to day - then talked and talked and talked. I finally got bored with him and started hoping that he expire. He raised some interesting points though...

The strongest thing in Earth's atmosphere is the force of gravity. Gravity is responsible for holding everything on Earth's surface and keeping the atmosphere from drifting away into space. It also plays a crucial role in shaping weather patterns and air movements.

Masks are used in a science lab to ensure safety and protect against potential hazards. They help prevent the inhalation of harmful chemicals, dust, or particles that may be present in the lab environment. Masks also help minimize the risk of contamination and spreading of microorganisms.

Some common characteristics of old age streams include decreased flow rates, reduced water volume, increased sedimentation, and a shift in dominant plant and animal species. Additionally, old age streams may exhibit wider and shallower channels, more frequent meandering, and a decrease in overall geomorphic activity.

Early settlers made jewelry using natural materials that were readily available to them, such as shells, bones, stones, and animal teeth. They would shape and carve these materials into beads, pendants, and other decorative pieces, and then string them together using plant fibers or animal sinew. Some settlers also melted and molded metals like gold and silver to create jewelry, but this was less common due to limited resources and tools.

A substance is considered highly combustible if it has a low ignition temperature and can rapidly release a large amount of heat and energy when exposed to a flame or spark. Highly combustible substances often have a high fuel-to-air ratio, meaning they can burn easily even in the presence of limited oxygen. Additionally, these substances may have volatile components that evaporate quickly and create a flammable vapor or gas.

The property of a salt that enables it to absorb water from the atmosphere is known as hygroscopicity.

The observable change for burning a log is the production of heat, light, and smoke.

Gasoline, a similar compound to petrol is made up of hydrogen of carbon. Called hydrocarbon. It comes from crude oil. So, yes it is a chemical compound, but isn't everything ? Water= H and O Steel = Fe and C .

The national symbols of Australia include the Australian flag, the national coat of arms, the kangaroo, the emu, and the golden wattle (Acacia pycnantha) flower. These symbols represent various aspects of Australian identity, such as the country's history, wildlife, and flora.

A mass spectrometer is maintained in high vacuum to prevent interference from air molecules. Air molecules can disrupt the ionization process and affect the accuracy and sensitivity of mass measurements. Maintaining high vacuum ensures that only the ionized particles of interest are present, improving the performance and reliability of the mass spectrometer.

Matter cannot be created or destroyed in chemical and physical changes, as stated by the Law of Conservation of Mass. This means that the total mass of the reactants must be equal to the total mass of the products in any given chemical reaction or physical change. While matter can undergo changes in form or composition, its total mass remains constant.

Changes of state refer to the physical transformations that occur when matter transitions from one state to another, such as from a solid to a liquid, a liquid to a gas, or vice versa. These changes are caused by variations in temperature and/or pressure, and involve the breaking or formation of bonds between particles. Examples of changes of state include melting, boiling, and condensation.

Breaking a mirror does not cause a change in the chemical properties of the mirror itself. The act of breaking the mirror may result in physical changes, such as the mirror's fragments having sharp edges, but the chemical composition of the mirror remains the same. Mirrors are typically made of a layer of reflective material, like silver or aluminum, which is deposited on the glass surface, and breaking the mirror does not alter this composition.

Both string puppets and our bones and muscles rely on a system of interconnected structures to achieve movement. In both cases, a series of interconnected parts work together to create motion. String puppets use strings that are attached to various parts of the puppet, much like our bones are connected by muscles and tendons to create movement in our bodies.

The age of puberty can vary among individuals and populations, but it typically occurs between the ages of 9 and 15 in most countries. Factors such as genetics, nutrition, overall health, and environmental factors can influence the timing of puberty. However, there is no definitive data on the precise age of puberty in different countries as it can vary within regions and populations.

An atom is the basic unit of matter, consisting of a nucleus composed of protons and neutrons, surrounded by electrons in orbitals. It is the smallest particle of an element that retains the chemical properties of that element. Atoms combine to form molecules and compounds and are the building blocks of everything in the universe.

True. Pharmaceutics is the branch of pharmacy that focuses on the science and technology of preparing and dispensing drugs prescribed by doctors. It involves various processes such as drug formulation, drug delivery systems, and dosage forms.

Unhealthy elements in the air you breathe can include pollutants such as particulate matter, volatile organic compounds (VOCs), carbon monoxide, sulfur dioxide, nitrogen oxides, and ozone. These pollutants can contribute to respiratory issues, heart problems, and other health conditions when inhaled in high concentrations over long periods of time. It is important to minimize exposure to these unhealthy elements by staying indoors during peak pollution times, using air purifiers, and taking measures to reduce pollution sources.

Early scientists were not able to test their theories using advanced technology or conduct controlled experiments. They also lacked the mathematical and computational tools needed to fully analyze and validate their ideas. Additionally, they often lacked knowledge of underlying fundamental principles and had limited access to data and observations.

When butter is heated, it melts and undergoes a process known as clarification, where the milk solids separate from the fat. As it continues to heat, the milk solids may brown and give the butter a nutty flavor. However, if heated for too long, the milk solids can burn and give the butter a burnt or bitter taste.
