QuestionWhat is the temperature at which Fahrenheit and Celsius thermometer readings are equal? Asked by: Hamid A. Khan AnswerThe temperature at which Fahrenheit and Celsius thermometer readings are equal is: - 40 degrees.Well if you look at the conversion formulas for Celsius to Fahrenheit, or that of Fahrenheit to Celsius, you can manipulate it mathematically to answer this question. The conversion formula reads: T(F) = T(C) x 9/5 + 32
this means that the temperature of Fahrenheit equals the temperature of Celsius multiplied by nine / fifths, plus 32 degrees. If the temperatures are the same then the two 'T's' in the formula should represent the same temperature. So, t = t x 9/5 + 32
minus the nine fifths of t from each side to move it to the left of the equation. this leaves: t - 9t/5 = 32 ------> this leaves: - 4t/5 = 32 so then you multiply each side by - 5/4 to solve for t, and you get t = - 40 degrees!
(by the way, 't' times,(x), nine/fifths equals 9t/5) Answered by: Dominic Jones, D.B., High School Student |

10 Ways to Keep Your Kids Interested In Science

Young children are natural scientists: they ask questions, pick up sticks and bugs outside, and are curious about the world around them. But as they get a bit older, many kids gradually lose their interest in science. They might see it as just another task at school, something that doesn't apply to their lives. Of course nothing could be further from the truth, so here are ten ways you can remind your kids that science is everywhere. Most of these are fun for adults, too! Continue reading ...
