Is baking a loaf of bread endothermic or exothermic? Baking bread is an endothermic process. An endothermic reaction is one that must absorb energy, in this case heat, in order to make the reaction… Is burning sugar endothermic or exothermic? What are some examples of exothermic and endothermic processes? Exothermic processes Endothermic processes rusting iron […]
What if we lived in a star cluster?
What if we lived in a star cluster? Inside a globular cluster, there might not be enough building materials for a rocky planet like Earth to be formed. Even our Sun might have had trouble forming in those conditions. Binary star systems aren’t unusual in the Universe, but they are less likely to host habitable […]
Does a rhombus have four 90 degree angles?
Does the crankshaft drive the transmission?
Does the crankshaft drive the transmission? The crankshaft only connects to the transmission when the car is in gear and the clutch is engaged. If you press down on the clutch the crankshaft disconnects from the transmission. The transmission is connected to the output shaft, which is connected to the axles, which are connected to […]
When two phases are in equilibrium which is true?
When two phases are in equilibrium which is true? The basis for the rule (Atkins and de Paula, justification 6.1) is that equilibrium between phases places a constraint on the intensive variables. More rigorously, since the phases are in thermodynamic equilibrium with each other, the chemical potentials of the phases must be equal. What is […]
What is maximum spring potential energy?
What is maximum spring potential energy? When the kinetic energy is maximum, the potential energy is zero. This occurs when the velocity is maximum and the mass is at the equilibrium position. The potential energy is maximum when the speed is zero. Where is maximum potential energy? You can see how the total energy is […]
What is horizontal motion formula?
Can we stop tectonic plates from moving?
Can we stop tectonic plates from moving? For tectonic plates to stop moving, the Earth’s mantle will have to be too cold for convection to occur. If that were to happen, then it means the Earth’s outer core has likely solidified. On one hand, if heat can’t reach the mantle or Earth’s crust, then the […]
Why do waves transfer energy but not matter?
Why do waves transfer energy but not matter? Waves transfer energy but not mass The particles ‘take part’ in the wave by bumping into one another and transferring energy. This is why energy can be transferred, even though the average position of the particles doesn’t change. Does all energy travel in waves? Do all waves […]
What is the main idea of the rock cycle?
What is the main idea of the rock cycle? The Rock Cycle Diagram The main idea is that rocks are continually changing from one type to another and back again, as forces inside the earth bring them closer to the surface (where they are weathered, eroded, and compacted) and forces on the earth sink them […]
