Why does heat excite electrons? Electrons can also be excited by electrical excitation, where the original electron absorbs the energy of another, energetic electron. The simplest method is to heat the sample to a high temperature. The thermal energy produces collisions between the sample atoms causing the atom’s electrons to be excited. What does it […]
Which is the coldest thing in the universe?
Which is the coldest thing in the universe? It is also known as the Bow Tie Nebula and catalogued as LEDA3074547. The nebula’s temperature is measured at 1 K (−272.15 °C; −457.87 °F) making it the coldest natural place currently known in the Universe. The Boomerang Nebula is believed to be a star system evolving […]
What type of bond has the most potential energy?
What type of bond has the most potential energy? Strong bonds have low potential energy and weak bonds have high potential energy. Lot’s of heat and/or light energy is released when very strong bonds form, because much of the potential energy is converted to heat and/or light energy. The reverse is true for breaking chemical […]
What are two different ways a plant could control turgor pressure?
What are two different ways a plant could control turgor pressure? Plants could control their turgor pressure either by actively transporting proteins to inside or outside of the cells in order to import ions or other solutes to increase or decrease, respectively, solute concentration inside of the cell, or through leaves’ evaporation changing water concentration […]
What are the main points of cell theory of life?
What are the main points of cell theory of life? The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. Who […]
How do reflections work?
How do reflections work? Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection. Light reflects from a smooth surface at the same angle as it […]
What are examples of hydrosphere?
What are examples of hydrosphere? Hydrosphere Lake. Seawater. Earth. Ocean current. Sea ice. Wave. Water. Ocean. What is the difference between hydrosphere and geosphere? The geosphere is all of the rock, land and minerals on Earth, and you can remember this because ‘geo’ means ‘ground. ‘ The hydrosphere is all of the water on Earth, […]
What are the examples of stimuli?
What are the examples of stimuli? Stimuli include: Irritants. Sights. Smells. Sounds. Temperature changes. What are examples of physical stimuli? Doing intense physical activity (like playing a sport), feeling pain, going to the bathroom, eating, and having sex are the five strongest physical feelings I can think of. What type of stimuli do humans detect? […]
