Science Experiments

The colored candles because they are darker which attracts heat causing it to melt faster.

Yes, milk can clean a penny because it contains lactic acid, which can help break down and remove the dirt and grime on the surface of the penny. Simply soaking the penny in milk for a few hours and then gently rubbing it with a cloth should help to reveal its shine.

Depends on what kind of Acid,But Anyhow Polypropylene Dropper Bottles and any Super Hydrophobic - Containers cant be burnt

Pseudo critical pressure and temperature are values used to determine the compressibility factor of a gas. They are calculated based on the critical properties (critical temperature and critical pressure) of a gas and are used in the generalized compressibility chart to determine the compressibility factor. This factor helps in predicting the behavior of a gas under different conditions.

No, a hollow steel ball will not crush under water due to the buoyant force acting on it. The pressure from the water will be evenly distributed on the surface of the ball, therefore it will not collapse.

Density of a liquid increases with increasing depth because it is being compressed between the weight of matter above it's self and whatever is retaining it. Mass per unit volume (density) increases through only two ways condensing or abating heat.

When lime water reacts with carbon dioxide (CO2), it forms calcium carbonate (CaCO3), which is insoluble and gives lime water a milky appearance. This reaction is used as a test for the presence of carbon dioxide gas.

The mass of an object is a measure of the amount of matter it contains. It is a fundamental property of an object and is usually measured in kilograms or grams. Mass is different from weight, as weight takes into account the gravitational force acting on an object.

Johannes Kepler(1571-1630) was a German astronomy and natrual philosophere who was known for his ability in formulating and verifying the three laws of planetary motion, which are now known as Keplers's Laws.

The measurable part of an experiment is the aspect that can be quantitatively observed, recorded, and analyzed. This typically involves collecting data, taking measurements, or recording specific outcomes based on the variables being studied in the experiment. These measurable results are crucial for drawing conclusions and making inferences based on the experiment's findings.

Good question! The wavelength of some waves is longer than the diameter of the tube, and other wavelengths easily fit the tube dimensions. This means they will use different propagation methods along the tube, depending on frequency. [the experts call this a 'frequency dispersive medium'] . The ping is a descending note , so the higher frequencies ( = shorter wavelengths) are reflected first.

You may observe a similar effect with an echo from a corrugated iron fence.

Yes, salt increases the density of water by adding more solute particles, which increases the mass per unit volume. This phenomenon is known as salinity and it causes water to become denser and heavier, affecting factors like buoyancy and circulation patterns in the ocean.

1. Testing the acidity of household substances using pH indicators.
2. Investigating the reaction rates of different types of vinegar and baking soda mixtures.
3. Studying the effects of different types of salts on the freezing point of water.

boiling is caused by impurities in the water. . pure water wont boil until it comes in contact with an impurity like what is found in regular tap water. it can also boil explosively on contact of such an impurity

Yes, ships can use alternative sources of energy such as wind power, solar power, and hybrid systems that combine traditional fuels with cleaner alternatives like liquefied natural gas (LNG) or hydrogen. These alternative sources help reduce emissions and promote sustainability in the maritime industry.

Tornado strength is measured using the Enhanced Fujita (EF) scale, which ranges from EF0 (weakest) to EF5 (strongest) based on the estimated wind speed and damage caused. The EF scale takes into account the type and extent of damage to structures, vegetation, and other objects.

To create a volcano for a science fair, you will typically need baking soda, vinegar, dish soap, food coloring, water, a container (such as a plastic bottle), and cardboard or paper mache for shaping the volcano structure. Mix the baking soda, vinegar, dish soap, and food coloring in the container, then add water to create the eruption. Cover the container with the cardboard or paper mache to form the volcano shape.

coconut water which is nothing but the nucellus of its embryo is the rich source of growth hormone's, nutrients ,etc. so it is the very good source of all the requirements which a tissue culture needs.

when a tsunami wave hits shallow waters it increases in height....

With normal waves as a wave reaches shallow water the distance between the bottom and surface decreases forces the fast travelling wave to slow down but increase in height once the height of the wave above the waterline is greater than that of the distance between the bottom and surface the wave breaks

Aspartic acid is an amino acid with an acidic side chain, making it capable of donating a proton and acting as an acid.

We will have this type of experiment this coming Thursday. Maybe after the experiment, I can identify the Variables or when the experiment is going on. I keep on searching this question, but only this came out. Well, thanks! But, thank me, too as I will answer this question, soon.

A Pixel is a picture element. (pix + el...) It may be of any dimension suited to the use. The CRT screen in front of me is only a few million pixels, but is adequate for the purpose.

A nanometre is 10-9 of a metre.

To calculate the volume of water displaced by an anchor on the ocean floor, you can use Archimedes' principle. The volume of water displaced will be equal to the volume of the anchor that is submerged underwater. By knowing the density of water and the weight of the anchor, you can calculate the volume of water displaced.

The scientific name for bread mold is Rhizopus stolonifer.

The chemical formula for epoxy resin is C15H16O2.
