What happens when a hot body and cold body are kept in contact with each other? Thermal energy is moved from hot spots to cold spots by convection. Convection happens when hotter territories of a fluid or gas ascend to cooler regions in the fluid or gas. Cooler fluid or gas at that point replaces […]
Is electronegativity affected by effective nuclear charge?
Is electronegativity affected by effective nuclear charge? Electronegativity is how much an atom pulls in electrons. If there are a lot of shielding electrons, outer electrons won’t be drawn towards the nucleus due to the low effective nuclear charge, and so electronegativity will be low. Effective nuclear charge is directly proportional to electronegativity. Does Zeff […]
Is our food system sustainable?
Is our food system sustainable? In terms of environmental sustainability, our current global food system accounts roughly for 12.8 percent of our total global greenhouse gas emissions, and its contribution as a sector to climate change is quite significant. What are some examples of sustainable food systems? For example: Polycultural Permaculture systems that are desalinating […]
Why do guys name their cars girl names?
Why do guys name their cars girl names? One theory is that the habit carried over from men’s habit of calling ships “she” and naming ships after women, most often goddesses in ancient times. Similarly, when men became dependant on motor vehicles, they were an ornament of pride and cared for with great attention by […]

Why is a triple beam balance called that?
Why is a triple beam balance called that? Its name refers to its three beams, where the middle beam is the largest, the far beam of medium size, and the front beam the smallest. The difference in size of the beams indicates the difference in weights and reading scale that each beam measures. How many […]
What makes evidence accurate?
What makes evidence accurate? A reliable source is one that provides a thorough, well-reasoned theory, argument, discussion, etc. based on strong evidence. Scholarly, peer-reviewed articles or books -written by researchers for students and researchers. Original research, extensive bibliography. What is the most unreliable form of evidence? Although witnesses can often be very confident that their […]
How many electrons must be transferred to generate a charge of 1 C?
How many electrons must be transferred to generate a charge of 1 C? We know that the charge on an electron is negative, and it is -1.6⨯10-19 coulomb. We need to calculate the number of electrons constituting one coulomb of charge. Total charge required for 1Coulomb. So 1 Columb of charge contains 6 × 1018 […]

What is action spectrum and absorption?
What is action spectrum and absorption? The absorption spectrum indicates the wavelengths of light absorbed by each pigment (e.g. chlorophyll) The action spectrum indicates the overall rate of photosynthesis at each wavelength of light. It is a graphical representation of the amount of light of different wavelengths absorbed by a pigment. Which pigments are most […]
