Explain how to convert {eq}4.62 \times 10^6 {/eq} kilojoules to kilocalories. Energy: The concept of energy in chemistry can refer to several things. Examples include the heat energy transferred to a substance sample to increase its temperature, or the electrical energy generated by a s...
Across the stable density stratification of the abyssal ocean, deep dense water is slowly propelled upward by sustained, though irregular, turbulent mixing. The resulting mean upwelling determines large-scale oceanic circulation properties like heat and
(a) The frequencies of infrared waves are lower than the visible light vibrate not only the electrons but entire atoms or molecular of a body. This vibration increases the internal energy and temperature of the structure. That is why infrared waves are o
The branch of chemistry that deals with the changes of energy and heat of a system is referred to as thermodynamics. It tells about the conversion of thermal energy into various types of energy and how it can be affected.Answer and Explanation: Enthalpy Enthalpy is a thermodynamic term which...
An easy-to-understand explanation of how flywheels can be used for energy storage, as regenerative brakes, and for smoothing the power to a machine.
Please explain this equation in text: "energy transferred = coulomb x voltage". According to the first law of thermodynamics, if the internal energy is equal to the change in heat added to the system and the work done by...
all samples were centrifuged for 15 min at 12000 rpm and 4 °C. After centrifugation, 300 μL of the supernatant was transferred into a fresh 1.5 mL tube. Then, 70 μL portions of the mixture from each sample were mixed to form the QC sample. The supernatants were dried ...
When the paper moves near the upper belt, its strong charge attracts the charged toner particles away from the belt. The image is rapidly transferred from the belt onto the paper. The inked paper passes through two hot rollers (the fuser unit). The heat and pressure from the rollers fuse ...
How is energy transferred during convection? Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. What type of substance does conducti...
(Specific heat capacity of water = 4.184 J/g degrees C) How to calculate the approximate amount of heat necessary to raise the temperature of 50 grams of liquid water from 10.0 degrees C to 30.0 degrees C? Calculate the amount of heat energy transferred when the t...
