Waec Model Questions Vol1 2020 Physics Question 48
Practice objective / multiple choice question 48 from the 2020 Waec Model Questions Vol1 Physics examination.
A metal rod of length 2 m is heated from one end. If the temperature at the heated end reaches 100 °C and the temperature at the other end is 20 °C, calculate the rate of heat transfer through the rod if its thermal conductivity is 200 W/m·K. Then, if the length of the rod is doubled while keeping the temperature difference the same, what will be the new rate of heat transfer?
