A perfectly insulated aluminium rod has length 50 cm and cross-sectional area 3.0 cm? At the steady steady state, the temperature at 0 cm and 50 cm ends are 150 ° C and 50° C. Thermal conductivity of aluminium is 210 Wm' K'. Calculate the rate of heat flow.

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!

Can you match these to the correct definition
