Why we should not ban smoking?
Why we should not ban smoking? Scientists agree that smoking is dangerous. Tobacco smoke can cause cancer, strokes and heart disease.

What does it mean if a circuit is in steady state?
What does it mean if a circuit is in steady state? In electronics, steady state is an equilibrium condition of a circuit or network that occurs as the effects of transients are no longer important. Steady state is reached (attained) after transient (initial, oscillating or turbulent) state has subsided. Why does a capacitor act as […]

How does covalent bonding affect melting point?
How does covalent bonding affect melting point? Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds. What type of bonding has the lowest melting point? Covalent Molecules Which bond is strongest […]

Ground-level ozone, the topic of this website, is “bad” because it can trigger a variety of health problems, particularly for children, the elderly, and people of all ages who have lung diseases such as […]
Is earthquake epicenter randomly distributed on Earth?
Is earthquake epicenter randomly distributed on Earth? Earthquake epicentres are not randomly distributed on earth. They occur wherever two tectonic plates meet. The collision of these plates leads to the occurrence of earthquakes and volcanoes. About 75% of world’s largest volcanoes and 90% of earthquakes occur along the Pacific Ring of Fire. How do you […]
