Which heat transfer happens through fluids? convection What material does not conduct thermal energy well? Metals are very good thermal conductors. Materials that are poor conductors of thermal energy are called thermal insulators. Gases such as air and materials such as plastic and wood are thermal insulators. Where is the most heat trapped on road? […]
Is h2so3 a strong electrolyte?
Is h2so3 a strong electrolyte? It is a weak one. It is not a strong electrolyte because it has one less oxygen than H2SO4, by comparison. Is water a weak electrolyte? Water is also considered to be a weak electrolyte. That is, only a small fraction of the H2O molecules in water dissociate to form […]
What is the smallest distance two points can be separated and still resolved using light microscopy?
What is the smallest distance two points can be separated and still resolved using light microscopy? The resolution of a microscope or lens is the smallest distance by which two points can be separated and still be distinguished as separate objects. Why are viruses not resolved by a light compound microscope? Unlike other unicellular organisms […]

Is acetic acid a Nonelectrolyte?
Is acetic acid a Nonelectrolyte? Solutions can be divided into electrolyte and nonelectrolyte solutions. Electrolyte solutions conduct electricity. Acetic acid (the acid in vinegar), citric acid (the acid in citrus fruits), and other organic acids are weak electrolytes. What types of compounds are Nonelectrolytes? A nonelectrolyte is a compound that does not conduct an electric […]
How is incomplete dominance expressed?
How is incomplete dominance expressed? Incomplete dominance occurs when neither of two alleles is fully dominant nor recessive towards each other. The alleles are both expressed and the phenotype, or physical trait, is a mixture of the two alleles. In less technical terms, this means that the two possible traits are blended together. What is […]
Can a real machine be 100% efficient?
Can a real machine be 100% efficient? No machine is free from the effects of gravity, and even with wonderful lubrication, friction always exists. The energy a machine produces is always less than the energy put into it (energy input). That is why 100% efficiency in machines shall not be possible. What are 6 simple […]
Why we need to protect our soil?
Why we need to protect our soil? Soils filter surface water of dust, chemicals and other contaminants. This is why underground water is some of the cleanest sources of water. Healthy soils help protect the planet from climate change. How can we protect soil biodiversity? It is preferable to avoid degradation in the first place, […]
What is measured in tonnes?
What is measured in tonnes? Ton, unit of weight in the avoirdupois system equal to 2,000 pounds (907.18 kg) in the United States (the short ton) and 2,240 pounds (1,016.05 kg) in Britain (the long ton). The metric ton used in most other countries is 1,000 kg, equivalent to 2,204.6 pounds avoirdupois. What is meant […]
Do atoms share electrons equally?
Do atoms share electrons equally? Because they have the same electronegativity, they will share their valence electrons equally with each other. This type of a covalent bond where electrons are shared equally between two atoms is called a non-polar covalent bond. Can two atoms share a single electron? There is another mechanism for obtaining a […]
