Where is most water found on Earth?

Where is most water found on Earth? The ocean What does evaporation look like? Evaporation happens when a liquid turns into a gas. It can be easily visualized when rain puddles “disappear” on a hot day or when wet clothes dry in the sun. In these examples, the liquid water is not actually vanishing—it is […]

Are magnets bad for your ears?

Are magnets bad for your ears? There are no studies to suggest that the magnets and the relatively small magnetic fields in headphones have any negative effects on your brain, ears, and/or body. However, the sound levels produced as a result of these magnets may cause hearing damage if driven too high. Do magnets mess […]

What causes hydrogen bonding in water?

What causes hydrogen bonding in water? Hydrogen bonds are attractions of electrostatic force caused by the difference in charge between slightly positive hydrogen ions and other, slightly negative ions. The attraction between individual water molecules creates a bond known as a hydrogen bond. Is CH3F capable of hydrogen bonding? It is known that CH3F forms […]

Is stress a restoring force?

Is stress a restoring force? Ans: Stress is the measure of restoring force per unit area. Where is Hooke’s Law valid? Hooke’s law states that within the elastic limit, stress developed is directly proportional to the strain produced in a body. Hooke’s law is valid only in the linear part of stress-strain curve….The Hooke’s law […]

Why is the temperature changing?

Why is the temperature changing? But the global temperature mainly depends on how much energy the planet receives from the Sun and how much it radiates back into space—quantities that change very little. A one-degree global change is significant because it takes a vast amount of heat to warm all the oceans, atmosphere, and land […]

Como se mide la densidad de solidos y liquidos?

¿Cómo se mide la densidad de solidos y liquidos? Los instrumentos más comunes para medir la densidad son: El densímetro, que permite la medida directa de la densidad de un líquido. El picnómetro, que permite la medida precisa de la densidad de sólidos, líquidos y gases (picnómetro de gas). La balanza hidrostática, que permite calcular […]
