Pure liquids have molecules further apart from each other. Although molecules move about within the liquid, they are slow to pass heat to other regions compared to the free electrons in metals. This is because there are large inter-molecular distances ...

Bulb – Carries the liquid in the thermometer. It has a thin glass wall for effective heat transmission between the liquid and body whose temperature is taken. Capillary bore – Liquid expands and contracts along the capillary tube. It isnarrow for high ...

Sir Isaac Newton first presented his three laws of motion in the “Principia Mathematica Philosophiae Naturalis” in 1686. His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A ...

Sir Isaac Newton first presented his three laws of motion in the “Principia Mathematica Philosophiae Naturalis” in 1686. His second law defines a force to be equal to the change in momentum with a change in time. Momentum is defined to be the mass m of an object ...

For a particle with no charge and nearly no mass, the neutrino gets a lot of scientific press—and it’s no wonder it’s captured the attention of physicists (though non-physicists might, for the most part, be unaware that scientists have built ...
