Does temperature cause CO2 to rise?
Does temperature cause CO2 to rise? Figure 1 (Woods Hole Research Center, 2009) shows 400,000 years of carbon dioxide concentrations and temperature change taken from ice core data. Upon close examination of this record, it appears that temperature warmed first and was then followed by increases in CO2. Why does not eating meat help the […]
What kind of reaction is esterification?
What kind of reaction is esterification? Esters and water are formed when alcohols react with carboxylic acids. This reaction is called esterification, which is a reversible reaction. This type of reaction is called a condensation reaction, which means that water molecules are eliminated during the reaction. Is esterification a reversible reaction? Since the esterification reaction […]
What is the best method of teaching science?
What is the best method of teaching science? Real-life scenarios, peer-to-peer teaching, hands-on activities, science projects and field research journals are effective teaching techniques in the science curricula. Instruction in science often can foster greater interpersonal skills and independent thought. What is the basis of remedial teaching? Diverse methods and materials are used in remedial […]
How a chemical reaction takes place?
How a chemical reaction takes place? Let’s start with the idea of a chemical reaction. Reactions occur when two or more molecules interact and the molecules change. Bonds between atoms are broken and created to form new molecules. That’s it. What does it mean to classify a chemical reaction? Chemical reactions may be classified as […]
Why does internal reflection occur in raindrops?
Why does internal reflection occur in raindrops? As light enters the raindrop, it is refracted (the path of the light is bent to a different angle), and some of the light is reflected by the internal, curved, mirror-like surface of the raindrop, and finally isrefracted back out the raindrop toward the observer. How do you […]
How do you tell if a distribution is normal or skewed?
How do you tell if a distribution is normal or skewed? In a normal distribution, the mean and the median are the same number while the mean and median in a skewed distribution become different numbers: A left-skewed, negative distribution will have the mean to the left of the median. A right-skewed distribution will have […]
What are the three methods of magnetization?
What are the three methods of magnetization? Methods of magnetisation Stroking method. A bar of steel can be magnetised by stroking it with a bar magnet. Hammering. Electrical method. Can any material be magnetized? Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or […]
What are the causes of downwelling?
What are the causes of downwelling? What causes downwelling? Downwelling occurs when the water on the surface of the sea becomes denser than the water beneath it and so it sinks. Seawater gets denser when it gets colder or saltier. How does downwelling affect climate? Coastal upwelling and downwelling also influence weather and climate. Along […]
