What is the formula for mass and volume? Between 5 degrees Celcius and 10 degrees Celcius, which solute shows the greatest change in the amount that can be dissolved in 100 grams of water? The volume of a piece of metal is 10mL and mass is 15g, what will it's density be?
In a static electric field, the work required to move per unit of charge between two points is known as voltage. Mathematically, the voltage can be expressed as, Where work done is in joules and charge is in coulombs. We can define voltage as the amount of potential energy between two ...
Watt-hours can be used to determine the energy usage of various electrical devices, such as standard light bulbs, over time. Knowing the potential electrical power use of a device also provides insight into when it might need to be replaced. This information is also useful for determining if ...
Calorimetry is defined as the process in which the measurement of the transfer of heat during a physical or chemical process. The device which is used to measure the transfer of heat during a physical or chemical process is known as the calorimeter. An ideal or perfect calorim...
Hello, I was quoted a 16 seer 2.5 ton system and when installed the label says 14.5 seer. The hvac guy says its because the 16 seer rating is achieved by adding the 14.5 of the condenser and the coil with a txv is 1.5 seer for a total system rating of 16. Is this on the level...
For instance, an aluminum wall has a very high conductivity and so it will spread heat quickly. This is one of the reasons aluminum alloys are a good option for pots or pans to cook with. These three factors result in the conductive heat flux. In the following formula, (Mills, 1999),...
The wavelength required to break a chemical bond depends on the bond's dissociation energy. The energy of a photon needed to break a bond can be calculated using the formula \(E = \frac{hc}{\lambda}\), where \(E\) is the bond dissociation energy, \(h\) is Planck's co...
