What is the boiling point of water?
The boiling point of water is 100°C or 212° F. Generally, the boiling point of a liquid is the temperature at which the vapor pressure is equal to 760 mm (the standard sea-level atmospheric pressure). When boiling a liquid at any temperature,
What is the difference between Magnetism and Gravity?
The only similarity between magnetism and gravity is that both are forces. Aside from this little similarity, there is a big difference between the two. In a simple term, gravity is usually explained to be a universal force exercised by two bodies on
Who coined the equation E=mc^2 and what does it mean?
The correct answer to this question is Albert Einstein. He is a physicist, who coined the term. This is a formula, which correlates energy to mass. When he originally wrote the question, he wrote it as m=L/c2. The L represented Lagrangian, which is a
