Is R410A going to be phased out? All new home AC units in North America uses R410a, also known as Puron. But this refrigerant will consequently be phased out. This is due to a continued focus on reducing compounds known to have an effect on the environment. But it’s not so much the air conditioning […]
Does speed affect torque?
Does speed affect torque? Torque is the rotational equivalence of linear force. Speed measures the distance covered in unit time. The relation between torque and speed are inversely proportional to each other. The torque of a rotating object can be mathematically written as the ratio of power and angular velocity. Does more torque mean more […]

What benefit did the invention of the compass by the Chinese bring society?
What benefit did the invention of the compass by the Chinese bring society? Also, the magnetic compass allowed people to map out the world as they knew it, since they now knew what direction each country was in. Therefore, the magnetic compass effectively allowed Europeans to navigate across oceans and expand their empire, colonizing and […]
What bad has happened in 2020 so far?
What bad has happened in 2020 so far? The worldwide death toll from COVID-19 exceeds 700,000. Harvey Weinstein was convicted of rape and sexual assault in New York. The 2020 Summer Olympics, which were supposed to take place in Tokyo, are postponed until 2021. A Ukrainian flight crashes in Tehran, Iran, killing all 176 passengers […]
What is the process of fractional distillation?
What is the process of fractional distillation? Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate. What is the process of cracking? Cracking, in […]
What does the compressor do in the vapor compression refrigeration system?
What does the compressor do in the vapor compression refrigeration system? The compressor does the work to raise the pressure, and the expansion valve assures that adequate pressure is retained in the condenser for heat transfer. The vapor compression cycle can be used to cool air, liquid, or cold plates. In what condition does the […]
What is a power supply of a computer?
What is a power supply of a computer? A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage. […]
Which sorting algorithm is best for sorted array?
Which sorting algorithm is best for sorted array? When the array is almost sorted, insertion sort can be preferred. When order of input is not known, merge sort is preferred as it has worst case time complexity of nlogn and it is stable as well. When the array is sorted, insertion and bubble sort gives […]
Why does steel become brittle at low temperatures?
Why does steel become brittle at low temperatures? Cooling just about anything to liquid nitrogen temperatures makes it more brittle than at higher temperatures. At higher temperatures, defects in the crystal lattice of a material are more mobile. At lower temperatures, the nearby atoms in the crystal lattice do not move and long cracks can […]
