That’s what air conditioning does. There’s no way to “make cold air.” What we call “cold” is just the absence of heat. If you want to cool the air around you, the only way to do it is to remove heat. And the time-tested best way of doing it is through evaporation. How...
Emissions control is central to the biodiesel argument, especially in legislation matters. There are a few components of emissions that are especially harmful and cause concern among scientists, lawmakers, and consumers. Sulfur and its related compounds contribute to the formation of acid rain; carbon...
Depending on the definition used, 1 BTU is equal to between 1,054.35 and 1,059.67 joules. Energy, and in particular, heat, is also sometimes measured in calories, with 1 calorie being the amount of heat required to raise the temperature of 0.035 ounces (1 gram) of water by 1.8°F (1...
Heat is the energy transferred in a process due to a difference in temperature. Heat is usually expressed using specific units like Joules or calories. These units of measurement can be interconverted using specific conversion factors.Answer and Explanation: ...
This is a measure ofequipment energy efficiency over the cooling season.It represents the total cooling of a central air conditioner or heat pump (in Btu) during the normal cooling season as compared to the total electric energy input (in watt-hours) consumed during the same period. SEER is...
A thousand joules is equal to a British thermal unit. 1,000 joules = 1 Btu So, it would take 2 million joules to make a pot of coffee. The term "joule" is named after an English scientistJames Prescott Joulewho lived from 1818 to 1889. He discovered that heat is a type of energy...
One BTU is equal to approximately 1,055 joules. One joule is equal to: 1× 107 erg (exactly) 6.24150974 × 1018 eV 0.2390 cal (gram calories) 2.390 × 10-4 kcal (food calories) 9.4782 × 10-4 BTU Units defined exactly in terms of the joule include: 1 thermochemicalcalorie = ...
Using the energy method, try to derive the equation of motion for system shown in the figure. What is the difference between primary and secondary bonding in the structure of materials? Determine the theoretical cleavage strength for ? Si 3 N 4 if its surface energy is equal to 30 J/m 2...
This scale uses the same increments as the Celsius scale; for example, a temperature change of 1 C is equal to 1 K. However, the Kelvin scale starts at absolute zero, the temperature at which there is a total absence of heat energy, and all molecular motion stops. A temperature of 0 ...
The SI unit of energy is Joule which is named after James Prescott Joule and the unit is same as the unit of power. The CGS unit of energy is erg. Visit BYJU'S to learn more.
