A system gains 227 J of heat, at the same time the environment does 234 J of work on the system. Find the change of the system. The unit of the internal energy is Joule, but no need to write the unit in the answer box. Be careful, the negative, in that case, one needs to write the answer along with the negative sign. During the winter freeze of last February 2021, damage occurred to a plant at temperatures of 16 F. What is this temperature Kelvin scale? No need to write the unit. Please write the answer in one decimal place. (e.g. 1.234 should be written as 1.2). The ends of a cylindrical steel rod are maintained at two different temperatures. The rod conducts heat from one end to the of 7 cal/s. At what rate would a steel rod 4 times as long and with twice the diameter of the previous rod conduct heat betw two temperatures
