Science Experiments

Silver nitrate is composed of one silver atom, one nitrogen atom, and three oxygen atoms.

If the body is approaching towards the center of earth,then the K.E and Gravitational (G) energy imposed on body due to earth are parallel and in the same direction,hence they can be combined.

If the body is moving on earth's surface,then its K.E is perpendicular to the (G), and if body is moving away from earth its experiences -ve gravity !!

In a fair test, only one variable should change while all other variables are kept constant. This helps to isolate the effect of the variable being tested and ensure that any observed changes are a result of that specific variable.

The distance between an object and a convex lens affects the position, size, and orientation of the image formed. When the object is placed beyond the focal point of the lens, it forms a real and inverted image. When the object is placed between the focal point and the lens, it forms a virtual and upright image.

No, mango seeds do not all germinate at the same time. Germination can vary based on factors like the variety of mango, environmental conditions, and seed quality. Some seeds may germinate quickly, while others may take longer or not germinate at all.

pipette out 8.5 ml perchloric acid in to 500 ml acetic acid and add 21 ml of acetic anhydride make up to volume to 1000 ml with acetic acid*.

* Let this solution stand for one day and check the water content

Stirring an experiment helps to ensure that all components are evenly mixed and distributed, reducing the likelihood of inconsistent results due to unequal distribution or settling of particles. This can lead to more accurate and reliable data by maintaining consistency throughout the experiment.

if you take a look inside a bamboo stick there is a membrane layer; there isn't a cell wall.

Soap is a surfactant, which means it can break down and remove oils and fats from surfaces. When you use soap to wash off fat, the soap molecules surround the fat molecules and allow them to be rinsed away with water, effectively removing the fat from your skin or dishes.

Approximately 140 people died in the Oshima eruptions of 1741 and 1745.

When a solution is saturated that indicates that solution is at a maximum concentration. The solvent is unable to dissolve more of the solute. If more of the solute it placed in the solution, it will not dissolve, yet rather sit at the bottom as a crystallised form. The temperature can also affect the capacity of the solvent's abilities to dissolve the solute eg. it is easier to dissolve sugar into a drink if it is hot than when it is cold. Sometimes if the drink cools down, the crystals settle at the bottom.

No, a dependent variable is the factor that is being measured or observed in an experiment in response to changes in the independent variable. It is the outcome or result that is affected by the independent variable.

The oil drop experiment was conducted by Robert Millikan in 1909 to determine the charge of an electron. The hypothesis was that the charge of individual oil droplets could be determined by observing them falling in an electric field and measuring the forces acting on them. This experiment provided an accurate determination of the charge of an electron.

A plant needs carbon dioxide to live, and air is combined of CO2(carbon dioxide), H20(water) and Oxygen (, O, 8).When people exhale they breathe out CO2, which a plant absorbs. CO2 is a nutrient, essential to a plant.

Yes, observations made during an experiment are referred to as data. Data can include measurements, descriptions, and other information collected during the experiment to support analysis and conclusions.

The strongest human memory tends to be highly emotional or traumatic events, such as a life-threatening situation, major life milestones, or events that evoke intense feelings. These memories can be deeply ingrained in our minds and may be recalled vividly even years later.

It's homogeneous because you can't see or take apart the different ingredients..

In a heterogenous mixture you can see and take apart the different (basic) ingredients, an example would be, cereal and milk in a bowl...

The variable in an experiment that is being measured or tested is usually referred to as the independent variable. In the case of testing the effect of water temperature, the independent variable would be the water temperature itself.

It depends on whether the heart beat is being changed (dependent variable) or if the heart beat is changing something else (independent variable) P.S. The independent variable is the thing that was changed, while the dependent variable is the data collected through observations and measurements ( aka how the independent changed the dependent).

When you mix fresh water with salt water you get what is called brackish water. An estuary is a body of water where fresh water and salt water mix. You'll find all the brackish water you need in estuaries where rivers meet the sea.

Having a high density means that more atoms are packed into a smaller space. The most dense element in the Periodic table is Lead.

Density can be calculated by dividing an object's mass by it's volume, as expressed by p = m/v.

The variable that is affected by the independent variable is called the dependent variable. It is the outcome or response that is being measured or observed in an experiment. The dependent variable is expected to change in response to changes in the independent variable.

An experiment is designed to have only one independent variable at a time in order to clearly identify and understand its effect on the dependent variable. This helps to avoid confusion and ensures that any observed changes in the outcome can be attributed to the single independent variable being tested.

Changing only one variable in an experiment allows researchers to identify the specific impact of that variable on the outcome being measured. It helps to isolate the effect of the variable being studied and avoid confusion from the influence of other factors. This method provides more accurate and reliable results in scientific investigations.
