What is heating curve? A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. The plateaus on the curve mark the phase changes. The temperature remains constant during these phase transitions. Which phase is the easiest to heat? Solid Why does the entropy increase dramatically at the […]

What part of Earth absorbs the most sunlight? the equator What absorbs the sunlight? Chlorophyll is what absorbs the sun’s energy and turns it into chemical energy. Not all the light energy from the sun is absorbed. Sunlight has many different colors in it. Chlorophyll usually absorbs red and blue light from the sun and […]

What are 2 differences between the 3 types of bonds? Explanation: Covalent bonds are where two atoms share electrons. The orbitals that electrons sit in overlap between one atom and the next, which satisfies both of them and makes them stable. Ionic bonds are more like blood donations. A metal atom gives electrons to a […]

Is it better to breathe through your nose or mouth when exercising? The nose also adds moisture and warmth to inhaled air for smoother entry to the lungs. Nasal breathing, as opposed to mouth breathing, has another important advantage, especially for effective and efficient exercise: It can allow for more oxygen to get to active […]

What does a new moon indicate? As a new moon represents the start of a new lunar cycle, it symbolises new beginnings. People use the energy of a new moon to achieve their goals or start on a new project. They also reflect on their old goals and set themselves new ones. What should I […]

Is magnesium chloride harmful? Magnesium chloride supplements are considered safe if used as directed. Common side effects include stomach upset, nausea, diarrhea, and vomiting. Many of these side effects can be alleviated by taking the supplement with food. Nearly all forms of magnesium supplements have a laxative effect. What are the benefits of magnesium chloride? […]

¿Qué es el análisis dimensional? ANÁLISIS DIMENSIONAL El análisis dimensional es una rama auxiliar de la física que estudia la forma como se relacionan las magnitudes derivadas con las fundamentales. ¿Qué magnitud se obtiene al dividir las ecuaciones dimensionales de la energía y el peso? Respuesta certificada por un experto La magnitud que se obtiene […]

Do atoms lose energy when they collide? To loose energy in any other way, say by collision with another atom, then that atom has to carry away the difference in energy just as the photon did. Note that a collision can also add energy by the same reasoning, as can absorbing a photon so the […]

What are the two types of reflection? The reflection of light can be roughly categorized into two types of reflection. Specular reflection is defined as light reflected from a smooth surface at a definite angle, whereas diffuse reflection is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure […]

Are enzymes used up in a reaction? Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a […]
